will all the planets in our syustem be destroyed?
by frank crona on April 12th, 2006
I'm afraid you're right again.
by Quirkie on April 12th, 2006
Frank, not when the Sun goes red giant. At most it will only grow out to Mars.

but u have to compensate for the increased gravity and the extreme flamability of the outer planets(excluding pluto)
by Christ IS Lord on January 12th, 2007
There will be no increase in gravity because the will be no increase in mass in the Sun. Actually, there is a very slight decrease in mass taking place as the Sun fuses hydrogen to produce energy (E=mc^2), but that is not enough to worry about. Additionally, the outer planets are not particularly flammable. Yes, they are made of flammable substances, but in order for those substances to burn, they also need an oxidizer. This they lack. The internal temperatures of the outer planets is really quite high. So, if they could burn, they would have been ignited a long time ago.

Here here!

Where, where?
by Glenn Blaylock on October 15th, 2007
Figure of speech. Was in agreement.
by Carnivalius on October 15th, 2007
[Rolls eyes and says in an exasperated voice] I know that. ;-)
.
Seriously, I think that the expression is supposed to be "Hear, hear" as in listen to what has been said rather than "Here, here" has in a location. Of course, I could be wrong about that.
by Glenn Blaylock on October 15th, 2007
Nah I think you're right there. It makes little sense the other way round.
by Carnivalius on October 15th, 2007
the human race will not move to another planet or galaxy but yes i do agree with almost everything else you said.:)

Depends if we get a heads up. If we get enough time (maybe 100 years) from when we know for sure that the Sun is entering it's giant phase then I think we might well move to another planet. It's amazing what people can do when they're motivated. Unfortunately probably only the very rich will be able to go or those that are vital to it's success (depends on the capacity really).
by Carnivalius on October 16th, 2007
This will not happen for another 5 billion years. Assuming no divine intervention, I would say that the odds are that humans as we know them now won't exist by then. We will have evolved into something else by then. Along with that, there is no telling what technologies we will develop along the way. Even if we never find a way around the light barrier, I would expect that we will develop some means of traveling between planets, where it be generational ships or suspended animation. Whatever the case, I very much doubt that our descendants will remain confined to this planet.
by Glenn Blaylock on October 16th, 2007
there is a type of transportation between planets its called a spaceship and we can go to other planets but the problem is that there isnt air on the planets and no gravity so what are you suggesting that when the sun swallows the earth whomever goes into space will have to fly around space until they run out of gas.
by Anonymous on October 24th, 2007
I'm afraid you've been misinformed. All the planets have their own gravity, if they didn't there would be nothing holding their own mass together and they would break apart.
Some even have atmospheres (though none are known to be breathable to us currently). So we can infact land on these planets and I'm sure with enough resources we can probably re-process any bases/spaceships atmosphere (and maybe replenish as needed Mars for example has plenty of Iron oxide), it just requires the money to develop such technology (the ISS already does this to some extent and the space shuttle).
by Carnivalius on October 25th, 2007
yea except mars by then would be the closest to the sun and no there isnt air on planets and u would have to find another solar system with a sun!!!
by Anonymous on November 29th, 2007
Actually that wouldn't be bad mars being close to the Sun. Sure we would then be only 0.6 Au away from the Sun, but it's surface temperature is lower so temperatures should be bearable or at least by technology quite habitable (more so than they are now). There is indeed no air on other planets as air is the term we use to describe the exact mix of gases on our earth. There is however air (in small airborne abundances) on many planets, even mars has a 0.2% abundance. But then again mars atmosphere is too thin to breathe anyway. But as I said there's nothing stopping you reprocessing materials or processing existing materials (like iron oxide found in abundance on mars or even the carbon dioxide that makes up the majority of the thin martian atmosphere) to release the oxygen contained. This has and can be done.
I still also disagree on your earlier comment about no gravity and having to fly round till you die.
by Carnivalius on November 30th, 2007
Sorry, there's a mistake. Tt should say "there is however OXYGEN on many planets" not air,
by Carnivalius on November 30th, 2007
I was also assuming the red giant in this analogy only expands to Earth orbit (hence 0.6AU), if it goes further we'll have to set up shop further out.
