i think this is a kinda morb thing but it sounds pretty interesting...
sorry if there's another thread excactly like this one but there are so many.....lol

earth would get VERY hot. ice caps would melt, and land would become sandy wasteland, so basicaly it would be like the game 'wild arms'.

We'd have 5 mins to live.
I believe earth is inside the radius of the projected size of the sun in supernova form (in other words, we'll become a part of it.

i'm thinking the four closest planet to the sun will get incinerated (sp?)

If I remember correctly, if the sun grows into a red giant (which it's supposed to eventually), the 4 inner planets will get swallowed up. (10000 degrees F...toasty :D) If the sun goes supernova (which it isn't supposed to), I think Earth will get blasted to bits a few minutes after we detect the supernova (i.e., REALLY bright light in the sky)

wouldn't that make Uranus inhabitable (heatwise)?

Probably. *very much into outer space* Well let's see. This is sort of a no brainer, actually. Several things could happen:
1) Earth will be swallowed up by the sun.
2) We'll explode right along with the sun.
3) The sun won't go supernova on us and will turn into a red giant. If this, then:
a) We'll be swallowed by the sun and melt into it.
b) The sun will stop just short of Earth, swallowing Mercury and Venus, but because the sun will be so close everything on Earth will die and it'll become inhabitable.
It's like Tanonev said: the Sun is supposed to become a red giant and not explode. This is because only the really large stars explode at death, medium size stars like our sun will just expand and expand, then shed its outer layers and become a dwarf, twirling and swirling, taking billions of years to completely cool down.

Ok, first, the sun will NEVER EVER supernova, it would have to be roughly 8 times bigger. Secondly, the Earth would only be swallowed IF the sun went red-giant(where a star starts fusing helium into carbon, instead of hydrogen into helium) Thirdly, the blast would be so immesureably huge, that once the blast hit us, it would be instant plasma-fication of earth, but our orbit would decay before that happened, causing all sorts of phenomenons. I implore you, save the astronomy to someone who knows what they're talking about.

its certain that the sun will turn into a red-giant eventually... since its the natural life cycle of every star

I suppose I worded that bit wrong... Yes, the sun will go red giant in about 5 billion years. By then, Earth will be a little more than twice as old as it is now, and humans will most likely have gone extinct. Actually, the nuclear fusion in stars is quite marvelous, hydrogen nuclei colide to form helium nuclei(eventually) and the denser helium goes to the core. Eventually, the sun will start fusing those helium nuclei into carbon ones. That fusing of elements into heavier ones continues until the chain reaches iron, after that, no star can create fusion. The sun, a medium sized star, won't go very far in that chain before it stops. The result of stopping fusion: the internal pressure drops, and the star collapses into a white dwarf, neutron star, or black hole, according to its mass. White dwarfs are a result of electron degeneracy pressure, and neutron stars a a result of neutron degeneracy pressure. A balck hole is the result of the star being so massive, it colapses into a point of infinite density. Supernovae are the by product of white dwarf and neutron star formation. Any questions?

Space is quite unpredictable though. We know nothing for sure. :mellow:

The closest planets would be engulfed by the enlarging of the sun (I don't think it would explode. Are you talking about it turning into a red giant?). Sadly, our planet would be incinerated.

If the sun goes supernova (which it isn't supposed to), I think Earth will get blasted to bits a few minutes after we detect the supernova (i.e., REALLY bright light in the sky)

No, we probably won't see a "REALLY bright light...". We'll be dead by then, most probably. XD After all, it takes 8 minutes and a half for the sun's light to reach us.

as my bro wud say "F'ed"

well, actually, the matter from the star would take alot longer to reach us than the light from it, the infared would cook us though...

Wow...this just so happened to be my homework, to find out what would happen...XD Thanks guys! And yeah, wouldn't the Earth be swallowed up by the Sun too?

Eeeh .. how come the sun won't turn into a supernova ? (i forgot everything from my gr9 sci/astronomy course :heh:)

& .. the sun will expand in a few billion years anyways , right ? Eventually everything within a certain range is going to melt , including us .. that is , if we don't all die from global warming/climate change in the next 100 years . :heh:

Simply: the sun won't supernova because it doesn't have enough mass. Instead, in around 5 billion years, it will run out of hydrogen fuel, and start using the helium it made from the hydrogen. when this happens, the sun will cool and expand and fry us. You live in toronto, right? that means you and I took the same stuff in Grade 9, and i don't believe that was covered...

It was covered at my school -- I just have really bad memory . What you've told me triggered some information at the back of my head . XD Thanks for the information ~

Ahh...my favourite topic from Science.

As the Red Giant expands, it will engulf the inner planets and possibly the outer planets. It will then collaspe on its own gravity and explode. From our star there are gas clouds left over. These clouds contains hydrogen and helium atoms, which is known as nebulae. These clouds will attract more atoms and will increase it temperature which compresses together and form a new star.

Eh, I said enough. If you want to know more.....
http://www.bbc.co.uk/science/space/stars/index.shtml

1. We all die
2. Why should you really care, you'll be long dead and turned into dust by then.

Quite beautiful, isn't it? almost eerily like life. Then again, the very atoms we are made of come from long dead nebulea. Ah... the stars...

Yup, it's really amazing that this is going to happen in the next 5 billions years....

Oh, and also our star is a small one. It will only engulf the inner planets. (I think). After it collapses on its own gravity, it will shrink into a white dwarf and later turn into a black dwarf. Then it will fade away.

If our sun was a huge star or a giant star, it will swell into a Red Supergiant and have the Supernova. Which explodes out and destroy the everything in the Solar System. And that is how our Black Holes come about.

it seams that you are all smart people. kind of off topic but does light really bend around stars?

Hmmm.....I don't know about that......Light travels in a striaght line.

But if light does bend around stars, there must be some kind of medium that makes the light bend around it.

And if it doesn't.....well, who knows?:think:

weeeeeeeeeeeeeeeee just did this topic in physics!!! my fav topic ever!

light bends?!

and the sun supernova-ing? the sun isn't a large enough star so it doesn't supernova but it will as everyone has said engulf the inner planets when the outer layer explodes....... so either way, we're dead....and become a part of the stars!!! yay!!!

Yep. Light does bend if you place a thick glass in front of the light bulb. Not right in front of it though. And you'll see the light ray bend.

You know that thing they say. Refraction is the bending of light.

And umm....dunno if that happens with the stars. :\

actually, light can bend without lenses. Using amazing amounts of gravity bends the light as if it were made of particles instead of waves. Most waves shows properties of particles, and vice versa. This is called "Complementarity".

Gosh... I never learnt that at school. Or did I?:think:

Everything [near the sun] will dissapear from the extream heat. Thats my guess.

Yes, light can bend. Think of it as this way, everything in the universe is made up of little things [atoms, lol]. All atoms are effected by gravity, thus light is effected by gravity.

Light isnt' made of made of particles, it sometimes acts that way, but it's actually electromagnetic radiation, travelling at velocity c

But everything that exists is made up of somthing, true?

that's how Einstein's general relativity was proven, he calculated how much the light of stars (which are located behind the sun) bends and they checked out the result during an eclipse. it's pretty obvious if you know about Einstein. Gravity bends spacetime and light follows the spacetime, thus light bends around stars.

@Radical_Dreamer: true.

PS: you're wrong Ripple_in_Eternity, light consists of photons and since photons are particles... well, go figure. But you're right about the electromagnetic part.. the photons behave like waves.

photons are just theoretical carrier particles, no? the way I see it, matter is just another form of energy, proven by e=mc^2, so in the end, everything is nothing tangible.

well, yes photons are carrier particles (bosons to be precise), but I wouldn't call them that "just theoretically". Also I'm not quite sure about this special case... the equation e=mc^2, because a photon doesn't have a mass that would mean it has infinite potential energie... or no at all... or somewhat in between? And what about the kinetik energie? oO x_x
aww, maybe this is going over the scope of this thread, but it would still be nice to know... n_n;

EDIT: ok, my thoughts on this... the photon as no pot. energy since it has no mass. The energy of light exists due to it's wave motion.

@Ripple_in_Eternity: it's proven that photons exist. And that they don't have a mass is pretty much unavoidable.

Now I wished to do Science again......:(

If we put a photon through e=mc^2, it returns zero energy, thats why I think its more theoretical than proven. I think we should make a physics and science disscusion thread, where those that can't wrap thier brain around certain things can ask us nerds.

You guys are going offtopic.

The whole galaxy get suck into the black hole left behind.

that's the stupidest thing I've ever heard :o please keep those thoughts to yourself... some people might believe what you say.. ._.''

Okay, I correct myself after some readings. The sun is too small to become a black hole and black holes can't suck galaxies. The sun is too small to be supernovered and so it would become a white dwarf and cool down to be a black dwarf.

Pretty much end of story... question=answered

We'd die simply.

Oh! They did this on Doctor Who once!! *Squeals.*
But, it was in the year 5 thousand, so I really don't think that we've anything to worry about...

i heard that it might be possible that we could live in one of Jupiters Moons. Europa or Io i think. Idk. the one with ice. If its neither then :P.
its also said that we could live on mars once the heat from the su burns up mercury of venus. and then we'll have to move every now and then. but that movie i watched was from years ago... so forget what i sid.

Aren't Mars and Venus closer to the sun and having a temerature of way higher than humans can tolerate.

Humans can probably make colonies like really really big spaceships after 100 years or so. We can all live in those iron or steel or whatever they are made of houses. Hmmm...:shifty: ...doesn't that sound smart...ok...no.:P

Ok...just a future guess.

That would be mercury, venus, earth then mars

=.= no not enough time and technology. we'd just all die... what abt food and all...

=.= no not enough time and technology. we'd just all die... what abt food and all...

What the f!ck? This is going to happen in *5 billion years.* That's not enough time to create spaceships/space stations that can support life? You don't have much faith in the human race do you? :heh:

Also, this is kind of a silly thread, as scientists have said what's going to happen a million times, and now everyone here is just repeating them, or making up silly crap. X3

In regards to the human race: if we aren't extinct 5 billion years from now, our technology will be so ridiculous that we'll have colonized the whole damned universe, plus half of the other universes that may or may not be out there, long before any of this happens. So we'd have nothing to worry about. :3

Hell, we wouldn't even have to move. We'd just fix the stupid sun, or move earth with a giant tug-ship. ;D

Hell, we wouldn't even have to move. We'd just fix the stupid sun, or move earth with a giant tug-ship. ;D

Now that's what I'm talkin' about!! The sun works for us!

We'll either be dead or have left by the time the sun began its red-giant phase. I'm betting on the former.

if the sun supernovaed? oh boy...of course yea it would be extremely hot, all vegetation would die. no grass for the cows to eat. they would eventually die. We would have no food or meat. then...we would die. =(

Well...if the sun did in fact supernova on us, we woud probably all die. Some stars convert into black holes after a short period of time after going supernova. We'd probably be pulled into the black hole. If we survived the trip, we'd finally know what's inside a black hole before dying.

I dunno what you guys consider 'probably' when you consider the chances of humans surviving a super nova... if u ask me, it would be approaching 0 (from the right =P).
First. don't confuse supernova with a Red Dwarf, which is ultimately the fate of our sun (by current models of prediction). Red Dwarf will bloat up from all the helium inside of it (after exhausting the hydrogen) and swallow up the earth and maybe Mars (don't remmeber if it did or not =P ).. so instant death is certain there.
Back to SuperNova, some thousand years ago (1006), people were enjoying a nice nightly time, and then a super nova happened some 150 thousand light years away (that means it took the light from the explosion 150 thousand years to reach our eyes after the explosion happened).. and the explosion was the third brightest object in the sky, you could read a book from that light.. im somewhat certain that a supernova is fatal at a distance of hundreds of light years away.. so.. it will destroy everything in its path.. =)

Ok, I really don't think the human race is gonna be around for 5 billion years (that's my religion talking), but if we were, we probably would have figured out how to pull a Zonama Sekot (sorry, Star Wars reference) and pack a massive engine onto Earth to pull it out of harm's way (possibly even to a new solar system with a much younger star).(In the Star Wars Extended Universe (that includes any and all Star Wars books and novels that don't cover the six movies) Zonama Sekot was a planet that exited its system when under threat by activating a massive planetary hyperdrive)

dude...seriously....wtf

LOL.

The sun will not go supernova. It's been proven. But, for the sake of the other side, I present this:

If we lived on another planet with, say, and star 8-9 times the size of the sun, It is possible that one day, the star (which we'll call, Fred) did go supernova, I think it would do one of the following things to the planet (which we'll call, Bob):

1) The infrared and UV light emitted by the explosion would give all of us 1x10^24 degree burns, killing us, and Bob is ingulfed by the explosion matter about 20 minutes later.

2) Nothing, because we will have moved to another planet and have forgotten about Fred and Bob.

3) Nothing we care about, because we're all extinct.

4) The remote possibility that in the seven seconds it takes for light to reach Bob from Fred, Bob is freed from it's gravitational restraints and sent hurling through space away from Fred. However, shortly after, because Bob has no Fred to warm it, we all freeze to death.

If Fred didn't go supernova, then it would swell causing one of the following:

1) Bob is swallowed by Fred.

2) Bob is almost swallowed by Fred.

3) Bob is unscathed by Fred.

4) The remote possibility that in the seven seconds it takes for light to reach Bob from Fred, Bob is freed from it's gravitational restraints and sent hurling through space away from Fred. However, shortly after, because Bob has no Fred to warm it, we all freeze to death.


Ok, I have some issues with the science in that... Firstly, it take 8 MINUTES for light to reach Earth from the Sun. If the light only took 7 seconds, Earth would only be around 1 964 250 km away from the Sun.

Secondly, NOTHING TRAVELS FASTER THAN LIGHT! Not even gravity! If the Sun were to just magically disappear one day, the Earth would still follow its orbit until the gravitational well released it. Amazingly, that would happen at the same time the light stopped reaching us.

Thirdly, Even though the Earth is moving along very quickly around the Sun, if the Sun were to supernova (the biggest explosions around since the Big Bang) there is no way our little planet could outrun the searing waves of plasma that would be our fate.

^exactly.

Secondly, NOTHING TRAVELS FASTER THAN LIGHT! Not even gravity! If the Sun were to just magically disappear one day, the Earth would still follow its orbit until the gravitational well released it. Amazingly, that would happen at the same time the light stopped reaching us.Wait, what? sauce plz Anything I can read up on?

That's the theory of relativity Dark Bring, I suggest you read some Hawkings / Greene book if you want to know more about the subject. Basically, the speed of light is the fasted speed with which information can travel, the earth would still be in the same orbit for 8 minutes even if the sun suddenly disappeared. The newtonian idea that gravity acts instantaneously has been discarded 90 years ago, when Einstein published his general relativity.

Edit: my bad, of course this was already know 1905 when he published his special relativity. The general relativity only adds curved space-time as the manifestation of gravity.

Interesting. It [Earth remaining in the same orbit for 8 minutes] has got nothing to do with inertia/momentum/etc? I'll have to read up on this later.

It's got nothing to do with inertia/momentum, because if that were true, according to Newton's first axiom, the earth would just fly off in the direction it currently has (tangential to the orbit), since no force exerts a pull towards the focus of the orbit. It's a purely relativistic effect. The earth just "does not know yet" that the sun has disappeared, because that would mean that the information that the sun disappeared traveled faster than light, which is impossible.

I couldn't have said it better myself

I think we would be in a bit of a pickle lol

Just to clarify, would inertia/momentum take over after that eight minutes of "doesn't know yet?
Of course, the inertia is there all the time, it's just that gravity exerts a pull on the planet for 8 more minutes after the sun disappears. After those 8 minutes the earth flies of in whatever direction it's currently heading.

the sun would destroy half the solar system.

half...? get real! =)

Quite simple: we would all die.

If life gives you lemons you make lemonade.

If the sun supernovas make s'mores.

It would be like a giant 5th of November party ^_^

Well, I wouldn't be too concerned about our sun going supernova (it won't). It would be more problematic if we were hit by the gamma ray burst of a nearby supernova (it would destroy the ozone layer), but that's rather unlikely to happen. Anyway, the earth would be too hot for life to exist long long before it turns into a red giant and since our Milky Way will collide with the Andromeda Galaxy in two billion years.... things will get rough. ;)

We know too much for our own good. Maybe thats a reason not to shun religion @_@

We know too much for our own good. Maybe thats a reason not to shun religion @_@I'm curious, why do you think this knowledge is bad for us? Also, you don't need religion to be ignorant... :heh: Would prayer cool down the sun or prevent our galaxy from colliding with Andromeda? I doubt it.
In any case, it is through science that we can possibly escape our doom one day (keep in mind that these events lie millions/billions of years in the future, and look at how far science progressed over the last century) :)
I find our knowledge about the cosmos fascinating, especially that we are even capable of figuring out stuff like this is totally awesome.

EDIT: And we get breathtaking pictures on top of that! (Thanks to the Hinode spacecraft)

Meh. I'm not worried.

1. I'll be long dead
2. If humanity hasn't destroyed itself, it'll be advanced enough to move to another planet
3. It'll be one hell of a light show

Also, you don't need religion to be ignorant... :heh:First Quote of The Year Detected. OwO

First Quote of The Year Detected. OwO
lol, hell yeah. And let me add to it:

Also, you don't need religion to be ignorant...but it sure helps. :heh:
Heheheheh.
And I'm not worried about the sun going supernova. That won't be for a bajillion years. Either we'll be extinct, or we'll be god-like. Either way, stupid exploding balls of gas will be no problem for us. ;)

If we were still living... we would all die... :mellow:

silly landstrasse, not if we live on spaceships by then. :think:

silly matt, wouldn't the spaceship melt? :think:

They'd still probably be to far to see it...But they'd probably leave a few probes behind to send images ^.^ [Hubble telescope anyone?]

How the hell can I miss something as funny to see as this.


sad, I missed the funny part. So who about a new suggestion - What if EARTH turned into a black hole? hooray!


If you were about to point out that this is not likely before you read this, Your head is full of void. Or maybe a supernova

what it won't? you just shattered my world-view.

Could you imagine a world without hypothetical question...?

That would be a boring world. And we probably wouldn't learn much, since thinking usually requires a lot of silly, hypothetical questions.

I think we should discuss Kou's scenario though, even if it was sarcastic.
If the Earth turned into a black hole...we'd all die! D:
That's only if it happened soon though. If it happened a hundred years or so from now, we'd probably be safe anyway. By then, we'd all have black hole suits, equipped with counter-gravity measures and ultra flashlights, and we'd all live in black holes happily.
I can't wait to live in a black hole! Thanks for bringing up the possibility, Kou!

And my head is definitely full of void; it's constantly sucking up wisdom and talent (and apparently the intelligence of all those fortunate to be close enough to bask in my light), making me the most awesome person ever. I'm so lucky! I'd hate to have a head full of supernova. I reckon that would cause constant headaches, with all the light and sound and whatnot.

Aie finds a worthy Nemesis for my sarcastic cynical paths!

Naw the hypothetical question itself wasn't stupid. some of the responses were :lol2:

Although if the Earth did turn into a black hole we'd soon find out whether the white hole theory is true or not.

I take pride in my relentless unhappiness and infinitely flowing snide comments.

True, if there's an afterlife we can look at our super-condensed (or super pulled apart?) corpses from. Otherwise we'd just be...dead.

There was once upon a time a discussion on whether hell existed or not.

If it does, by about now it should be crowded as hell


:lol2::lol2::lol2::lol2::lol2:



Super condensed corpse.. liek, condensed enough to force fusion?.. hey we might get a sun from that eventually XD

My question itself was a hypothetical question, I hope you all understood the irony there. -_-
And silly Kou! Souls are friggin' immaterial and so is hell, for heaven's sake (ahahaha....). But the question whether souls burn in a transcendental way... is still a quite intriguing one. But let's just assume souls are not immaterial, but have mass.
That leaves the possibility, that maybe the sun isn't powered by nuclear fusion, but, in fact, is actually hell! So what we observe as solar flares is in fact the eternal suffering of the tortured souls. And maybe... just maybe! we should get rid of stupid metaphysics and stay with what we can actually verify. Like HopelessComposer's awesomeness for example. That only appears to be delusional when you look at it in a superficial way.

That leaves the possibility, that maybe the sun isn't powered by nuclear fusion, but, in fact, is actually hell!
That whole post was hilarious, but that was easily the best line in it. The timing and rhythm of that sentence was awesome. Or maybe I just got lucky and read it in a good way. I don't know. I laughed either way. X3

Kou wins points for his exceptionally bad pun, too. Puns are a weird form of humor, considering the worse they are, the funnier they get.

I think it would hurt, no? lol

Uhm.... Honestly, we'd either burn to death or freeze to death...

Like the Dinosaurs!! :]

Assuming humans are alive in 5 billiion years, most likely we would have advanced on to another hospitable place, e.g. Proxima Cenatauri

I wouldn't be able to sunbake anymore :(

With the depletion of Ozone instead ,of a nice tone, you'd probably end up with cancer or carcinoma, assuming of course you used sunlotion. Eh? Because i know a good few who had that infliction and resulted in a dissection.

You make the assumption there's a habitable planet orbiting said star. In 100 years, I promise, there will be a list of earth-sized planets longer than the list of all exo-planets to date.

With the next generation space telescope (James Webb Telescope) and the new generation of giant ground based telescopes, that are currently being planed and build (such as the Giant Magellan Telescope) and of course the two missions especially designed to look for earth-like planets such as the "Darwin" mission of ESA and the "Terrestrial-Planet-Finder" of NASA, which will be launched within the next 10 years, I'm sure we won't need a hundred years for that. ;) It's more like 15 or 20 years imo.
The future of astronomy is so exiting! >_<

PS: I'm so looking forward to the Hubble upgrade this year! xd

We're a little out of point here, but since its interesting...


With all this "Space age" crap talking going on and the ever so upgrading telescopes and research drones we might find a planet with Earth like conditions, maybe if we're lucky. G of around 10 Newtons, size wouldn't really matter but 70% of the surface being covered with water would be nice with a pleasant Temperate weather and arable soil that switches four times during the planet's orbit cycle so we have seasons and can farm. It'd be even better if the planet rotated slightly on an axis with a "day" that's pretty close to our current 24hr Terran day, and yeah while on that idea why don't we also specify the orbit time to be roughly 365days 6hrs 15minutes and a few loose seconds.

Oh and make sure you don't have too many suns or humans won't be able to adjust to it. We need night. and defintely a moon (which cannot be a rather dim sun, has to be a moon that reflects our said sun's light, or god knows what kind of problems we might suffer) which has a cycle of roughly 30 foresaid days.

Oh bloody hell I forgot that we need like 20~1% of the air to be oxygen and 79~% to be nitrogen (or another inert gas, but should be nitrogen in case we need to be sure whether other life forms we're familiar with can breathe the air and be happy with it) Any excess sulfur, lead and crap like that in the atmosphere would surely kill us, and Hydrogen, being the most common element in the universe, is definitely out. That or its no smoking sign on the entire planet.

So if EVERY AND ALL (plus a few I've missed, but these are probably the most essential) of these conditions are met we have a Medium Terran Planet Sol Mark II That can roughly support six billion homosapiens along with standard native lifeform (which a huge percentage will become extinct after human settlement)

Otherwise its let's live inside dodgy airtight compartment-like building thingys with artificial life support and food production, while on the outside we have drone robots doing terraforming so in a few million year's time our decendants can walk out into the "sun" and breathe some fresh quality "air".

Or we evolve to meet the new environment. But apparently being toolmakers we no longer adjust ourselves. In Human Planet, the planet doesn't adjust you, YOU adjust the planet! [/russian accent]


Seeing as how many stars there are in the universe, surely there's got to be at least one other planet that's close to our Terra. Hey - maybe there are homo sapiens like creatures there that have just ran out of resources themselves too! We could BOTH find a third planet for all of us to live in!


Finding one is likely, but finding one within our reach isn't.

And seeing as how our science is evolving, I doubt we'd go anywhere after this. We've pretty much peaked our science, And any pioneer topics go deep into realms that now collide with our biological limit. Maybe space folding "warp" travel is possible, but is it possible with a biomass onboard? hell no.

Don't get me wrong Kou, I have never meant to imply that exoplanet research is done in order to find a next home for when our planet dies. It's about finding habitable planets, where life could have evolved and see whether it really did. We don't actually need to go there to do that, we just need instruments which are powerful enough to make the observations. I agree that finding a planet that is exactly like our earth is unlikely, especially one that isn't "far away" (in astronomic terms).
The problem I have with your post is that you're projecting our current level of technology onto the far future. It's already impossible to foresee the advances of technology for the next 20 years or so. Just think about it, in a few million years, if our technology really advances far enough to enable real space travel, you won't have problems with "waiting for a planet to be terraformed" and similar things. Who knows what humans will be able to do in a million years?
They'd probably just freeze themselves and unfreeze when the terraforming is done or something. Probably people won't even age at all, but waiting for so long might be boring, thus the freezing.
You're saying that humans don't evolve, because humans are toolmakers and thus colonising planets with slightly different attributes would be impossible. So what? We could just make us evolve. For a species that possesses the ability to travel between the stars, some "simple" genetic engineering wouldn't be a problem.

Maybe space folding "warp" travel is possible, but is it possible with a biomass onboard? hell no.
Folding space in a way that would make faster-than-light travel possible would require far to much energy. So yeah, I agree that it's unlikely ;)

Im very surprised this thread has made more then 100 posts. xD

I was rambling about the practical difficulties for finding another habitable planet since so many people were like "omg let's just find another place to live in"

The point is that by the time we need a new place to live, our technology will be great enough to surpass any "practical difficulties." ;)
But why would we need a new place to live anyway? It's not like the sun is actually going to supernova on us. = \
An intergalactic move would definitely be a nice change of pace, though. :)

We'll still get fried, though, when the sun goes into red-giant mode :3

Yeah, but that's in like five billion years. If the human race is still around then, and doesn't have beyond-godlike-powers, I'll be thoroughly disappointed (and very surprised!).

right :p

Haha, at the rate we're going now, we'll annihilate ourselves along with all other terrestrial lifeforms and possibly the chunk of rock we call Earth itself in a few centuries... I seriously doubt the human race would still be around by the time our sun comes anywhere close to dying.

Happy thoughts.

Lets all move to Jupiter!!
this probably wont happen in this generation anyways
when this happens, lets hope that our ever expanding technology
can overcome this nightmare

Jupiter is a gas giant, composed of bits and pieces of floating rock and ice, we can't really live on there with what we have now.

Mars and Venus are probably our best bets, since they're fairly close. I highly doubt it's possible to transfer the entire human population on another planet though.

I wouldn't call Venus our best bet... considered that it has a surface temperature of 461.85 °C.

Mars is where it's at. Go Mars! *cheers*

That's it? Dude, you couldn't even bake cookies on my ass with that heat.

We're talking about Celsius here, not Fahrenheit or kelvin, keep in mind (ha! I'd laugh if someone assumed it was kelvin first...). Along with the fact that the atmosphere of the other planets are dramatically different from that of Earth's, the surface temperature is only one of many many problems we'll have to overcome.

My statement still stands to be true.

What's the use of staying close to the sun (or go even closer) when it explodes? XD

@Asuka: that's 863 ºF, so yeah, since your arse would be burnt into a pile of ashes it would be hard to fry a cookie on it.

@Illuminuest: You move to jupiter, have fun getting crushed by huge gravitational forces and wotsnot.

Haha, I think if our sun really did explode, we'd need to relocate completely to another solar system. A huge task to embark on, especially considering our limited technology now.

yeah, don't forget the sulphuric acid in the atmosphere ;)

Hmm... all knowledge of the solar system I have came from Magic School Bus and Wikipedia =)

xD magic school bus and wiki?

Why move to a planet closer to the sun when we are trying to move away from it? xD We'll eventually get the technology we need to get to a new solar system or something. or we can move to a rock, that has nearly the same features as earth, close enough to another star?

We will probably have some technology that can stop it by then, just like the Chinese can make it rain...

I don't think stopping a star from exploding and making it rain can really be put into the same class like that. :heh:

Actually, our son won't explode. It's not big enough. However, it will probably eventually become a smaller-scale red giant (after which the earth could be enveloped by the corona of the sun, and even if it wasn't the atmosphere would boil away and earth wouldn't be able to support life) after it burns up the hydrogen in its core, but after that, it won't explode, but rather turn into a white dwarf or neutron star, with the corona of the sun drifting off and creating a planetary nebula.

It is highly unlikely, however, that humans, at least, will last that long anyway; it will take at least 3-4 billion years for our sun to start to wind down (the average life span of a medium-sized star like our sun is approximately 10 billion years, and astrophysicists estimate ours had been around about 5-6 billion years). Somehow I have a feeling we just won't last that long...

The end would have come before that could happen.

Oh woops, I just notice that we already decided that there won't be a supernova...woops.

hahah! well. our sun is a second stage sun. meaning that it has already exploded once, and became a white dwarf, and expanded to what it is now. so deathraider is right, it will become a red giant and the earth will be engulfed by it and we would all die. but i think humans would have already developed interstellar travel already by then =/ or so says Nostradamus. O.O

hahah! well. our sun is a second stage sun. meaning that it has already exploded once

:think:

Actually, it's a third generation star (but we don't want to be nit-picky, do we ;))

Oookay. third generation. but we'll still have to fly far far far far far away. Nostradamus says aliens would come. O.O

All those who believe in my God would be saved first.

yeah, don't forget the sulphuric acid in the atmosphere ;)
Its sulphur by the way, not the acid. the acid is only in liquid form.
Well, we've got a few million years to research that technology. ^^. plenty enough time. myabe an alternate dimension. O.O

I bet we can't even imagine the things we'll come up with by then, just like how couple centuries ago no one would believe it if we said we could have robots the size of a pin.

who knows? XD

Its sulphur by the way, not the acid. the acid is only in liquid form.

Wikipedia: The atmosphere of Venus, the second planet from the Sun, is much denser and hotter than that of Earth. The surface temperature and pressure on Venus are 740 K (467°C) and 93 bar, respectively. The venusian atmosphere supports thick persistent clouds made of sulphuric acid, which make optical observations of the surface impossible.

well. Clouds are technically liquid y'know?:)

... Dust clouds?

Oh yea. well, yea. that. urm. yea. well. x_x

Whoa...not to get too much off the subject but...I haven't been on for what seems like a lifetime xD, but it seems that this thread has become quite popular!
Anywho...my views (not to mention grammar) has changed...so I guess I'll give another opinion ^__^
Apparantly scientists believe that the Sun will eventually go supernova--in another billion or so years--I think...because, as you guys are sure to have already known, the Sun is a star, and eventually all stars die *is reminded by fanfic about pOt*...anyway, getting off the subject yet again *mentally slaps self*.
So...in a billion or so years there may be no life on Earth--or an Earth for that matter either. Then what do you guys think would happen...?

Perhaps there's life on another planet...?

The star would die anyway? It's not like our existence matters in that regard. ._.

That's very likely. :3

hmm, a billion years. Humans would have most probably be able to cross interstellar space by that time and would almost definitely settle on a new planet once the earth is gonna go Ka-put!

but well.. i dont really care since its "a few billion years" from now. :heh:

haha...That reminds me of tv shows and cartoons how people live in space with their awesome awesome space-cars and their awesome awesome space houses and their awesome awesome space-suits!!!
And we might even be able to make friends with some awesome awesome aliens! ^_^... now that's awesome!! :D
LOL! but really, i cant imagine what Earth would be like in a billion years time...
Humans may even die out before the sun or the earth goes KA-PUT!!!

I'm sorry, but that's quite a bit off... Yes, all stars die, but the more common death for stars is to collapse into white dwarfs after going red giant, then fade away. Not many stars (including our sun) are massive enough to die as a super nova. Our sun will most likely expand into a red giant once its hydrogen has all been converted into helium in about 4-5 billion years. Our sun is a very special star, brighter than average, and just small enough to have a long life span. There are, on the other hand, stars like Eta Carinae, which are so massive that they're likely to cause hyper novae, the likes of which are near unheard of.

Aight, Eta Carinae is awesome. As far as I know it's even a binary system of two stars. it's A pitty that the chances to still see Eta Carinae exploding within our lifetime is pretty low (rather in the next few thousand years, which is nothing in comparison to it's age). :/

Are you planning on dying before reaching the ripe old age of two thousand? Don't die on me, Matt!

I'm not planning on dying on you just yet. O: I have high hopes for cell biology to overcome that small obstacle that is death. Just as Woody Allen once said (yes, I love quotes), “I don’t want to achieve immortality through my work, I want to achieve immortality by not dying.”
