So there is talk that after billions of years, the sun will die and it will grow so large it will grow into the Earth.

So let's say humans live that long, and they build subterranean tunnels. Would that event of the Sun destroy Earth? If it doesn't destroy Earth, could humans survive such an event by living in subterranean tunnels?

No. The planet, itself, will be consumed by the Sun. There will be nothing left to inhabit.

@PhoenixPhail nmh. That's what im thinking. But if it does "die" down, does that mean less heat, ergo ... making it " liveable " for us humans ? I don't even know if thats possible.

@Umile The Earth will be reduced to a burned out cinder. There will be no means to support [i]any[/i] life. Not even cockroaches.

I'm not even sure we'll survive the current century, let alone billions of years lol

Which part of the sun enveloping the earth are you having a problem understanding?

Umile · 41-45, F

@Convivial care to expand on that? I mean, i get it. But. Explain it please.

Convivial · 26-30, F

@Umile the thinking is, and I'm no expert so this is probably off in some respects, as the sun runs down on energy, the gravitational force weakens allowing it to expand into what's known as a red giant.
Some believe it will expand out so it's surface will cover the earth..i don't care how deep your tunnels are at that point... You're screwed 😜

@Convivial lmao. nmh. Interesting.

No.
The sun's mass will grow as it enters it's dying stage.
It will gravitate toward the earth because we're already in it's orbit.
The seas will boil; all life will die as temperatures hit the hundreds or thousands of degrees and it's gravitational force will probably rip the earth to pieces before the heat vaporises anything left turning it to dust

@Picklebobble2 Best answer.....The earth will be ripped to pieces.....so no tunnels needed.

No because the sun affects our gravitational pull. We would need another planet.

Nihiless

Or maybe AI will destroy human kind long before the sun dies. 🙂
