Billions of years from now, when everyone thinks the sun will eat the Earth, will the Earth push away from it?

Question

Will conditions perhaps exist by then, that might form an environment that the planet could thrive in ? Can the universe , heal itself ? maybe move things around ? The sun isn't the only thing out there causing "conditions".

"skepsis"...I should have said, what if , because of the conditions going on to create the red giant, forces of gravity were formed somewhere else (?) that would phenomenally pull the Earth to a place where a pocket of oxygen has formed and humans could still possibly survive ?

Answer 1

Assuming that the sun, when it becomes a red giant, will swell to fill the earth's orbit, consider its density. The earth's orbit is 186,000,000 miles across and the sun is 864,000 miles across. The earth's orbit is thus about 220 times as far across as the sun. So if the sun's diameter expands to 220 times its present size, its volume expands by 220^3 times, which is something over 1,000,000. Its density will then be 1/1,000,000 its present density. It's now a little more dense than water (1 gm/cc) so its density when it swallows the earth will be about 1 gm per cubic meter. By comparison the same volume of our atmosphere weighs about 1.2 kg, so the sun, when it expands to swallow us, will be less than 1/10 of 1% as thick as our current atmosphere.

Answer 2

There are a lot of hazards in space that could do us in but the swelling of the sun to a red giant is really the only one we can predict at the moment. I'd tell you of the other possibilities but it would just scare you.

Surprisingly, it would be possible to move the earth further from the sun to avoid being destroyed as the sun becomes larger. Its something humans could actually do with just a little more technology than we have now. An asteroid could be moved to an orbit that would loop out beyond Mars, then back around the earth in a way that would slightly speed the earth up in is orbit around the sun. This would, over millions of years, move the earth substantially away from the sun.

Answer 3

Planets are not living beings. They don't need an "environment" to "thrive" in. Earth will be subject to the forces of gravity and inertia. If those change somehow, from a passing asteroid, a change in solar mass, a collision with something, its orbit will change. The expansion of the Sun could have some effect but the Earth will not consciously "react".

The Earth is properly Earth no matter what its atmosphere, water content, or average temperature. It could be completely inhospitable to humans and it would still be the Earth. Even inside the Sun, until such time as it dissolved into indiscernibility, it would be Earth.

Answer 4

that is probably that the Earth is as previous as scientists have self belief. by way of geology. we are in a position to work out how the Earth switched over over billions of years. yet something profound befell with the advent of guy. Evolutionary data of guy's progression is sparse. on an identical time as we share many gains with the apes, maximum mammals share an identical gains with purely hassle-free variations. even whilst making waiting an entire turkey at Thanksgiving, I ask your self on the similarity it has to a small toddler, with comparable anatomical gains. What environmental forces led to the Apes to evolve into Homo Sapien isn't sparkling. some intervention via some exterior ability seems logical. extra logical than rapidly up evolution.

Answer 5

In theory in about 4-5 billion years sun will enter it's red giant phase.

According to http://en.wikipedia.org/wiki/Sun

"While it is likely that the expansion of the outer layers of the Sun will reach the current position of Earth's orbit, recent research suggests that mass lost from the Sun earlier in its red giant phase will cause the Earth's orbit to move further out, preventing it from being engulfed."

So earth might still exist. But "Earth's water will be boiled away and most of its atmosphere will escape into space."

Answer 6

The Earth will be hit my an asteroid or get sucked into a blackhole before the Sun will eat it. More likely scenario would be the Sun burning up all of its gases and then collapsing in on itself, forming a supernova.

Answer 7

I'm sure the Earth won't be around that long .The chances of a collision with a huge asteroid are more probable as some of them seem to be getting closer to us .

Answer 8

There is no "healing". If the earth gets sucked in, it gets sucked in.

Answer 9

no the earth will not be pushed away. it will get incinerated.
