Hypothetical scenario: The Sun vanishes - Page 4

Would could always just evolve into some sort of mole people too. Force Evolution for the win!!!!! Then we could renew our continual war with the Crab People.

If we had 10 years of planning I can see genetics totally getting fucked with to breed super-men.

How long until the Earth is uninhabitable? I give it a week without sunlight before planet-wide riots break out. A month before most animals die of depression. And massive storms in the meantime will probably cover most of the land in snow, killing most of the vegetable life. Maybe the storms will continue until the heat of the seas is distributed evenly through the atmosphere, where it'll very quickly seep into space. I guess it's a question of how you define uninhabitable. I am however sure it'll spiral out of all control way too fast to organize anything like geothermal energy on a large scale. Which I haven't looked into but I wonder how long it'll last if we seriously try to keep the planet heated from the inside.

Don't underestimate the sun. :O

Heating the Earth's core ourselves, hm, perhaps our vast stockpiles of nuclear weapons will be our salvation after all!

Tell you what; I'll work on my geology when you learn some tact.

Only a minor portion of the Earth's geothermal energy comes from surface heating by the Sun,

And that geothermal energy is the particularly accessible stuff. Not that the rest is inaccessible, just not nearly as much.

Most of the heat, I'm given to understand, results from radioactive decay.

The idea of turning Jiupiter into another sun could probably be doable. They almost did it in the late90's/early 2000 when they crash landed the Galileo probe into it. The plutonium core erupted under the pressure and there was a huge freaking fireball that covered several thousand miles of Jupiter's surface. People on earth could see the ginormous red spot via telescopes and the reaction sustained itself for several days as it detonated the hydrogen and helium mixture that makes up it's atmosphere..

And that wasn't even USING a device that was meant to blow up, imagine launching a few nukes at it. The main problem with that is after you detonate it, will it be able to sustain it's own reaction? Is it's gravity strong enough to do what the sun has been doing? I'm going to say probably not, otherwise it would have already turned into a star. I think we'd get a REALLY big boom and then it would burn for awhile, maybe even a few years, but eventually it'll be gone.

Now if we could get Saturn to crash into Jupiter, then we might be walking the brown dwarf territory...

You know, provided with ten years notice we could get the second most massive planet in the solar system to smash into the most massive, and then relocate a couple tens of thousands of human beings there.

Yup.

Yeah, when you cut it out of context like that and completely remove the rest of the details you can make it look like I was stupidly saying pressure is the sole source.

But, you see...

...

Also there are major contributions from the decay of radioactive materials and the inside of the planet trying to rip itself apart against the force of gravity holding it together (which really ties in with the pressure and the spinning and such, but I said simple)

The sun is 1AU (astralogical unit(s)) away from the earth, which is roughly 7-8 light minutes, so obviously it would take us 7-8mins for us to even realize a change light-wise.

If the sun disappeared? We would all die.

You know, rather than trying to launch nukes at Jupiter to light it on fire, why not, y'know, use them to trash the barrier around the sun? It's not gone or burned out, just hidden. Even if the aliens come back, we've got enough stockpiled to follow them home and make their planet go the way of Krypton.

Violence is your first resort? How typical. That barrier has feelings too, Blues.
