Will there still be people alive when the sun is gone?

Question

Answer please...

Answer 1

Not on Earth, but if you figure people have only been in anything resembling the current form for the last 200,000 years, and we have about 5 billion years before the red giant sun gets too hot for life on earth, it may be possible for our descendants to figure out a way to relocate.

I'll bet that those descendants won't be very recognizable to us, though.

Here's hoping we don't blow ourselves up, first.

Answer 2

No. First of all the sun is going to swell to the size of a red giant before it burns out which will disintegrate all life on Earth. And if we do live by some miracle, when the sun burns out there would be no light, and because our atmosphere is going to be gone. Temperatures will approach absolute 0.

Answer 3

During and after the sun goes through its red giant phase, I can't imagine any way life could survive on this planet.  I know it would be 4 or 5 billion years from now and perhaps whatever intelligent beings who live on this planet will have incredible technology. But the hostility of this planet's environment would make life here impossible, even with the most advanced technology, IMO.

It would be better for small groups of humans to go out into space, looking for other worlds or living in colonies floating in the outer solar system.  How they would survive is beyond our technology now. In those times, staying on earth just doesn't seem to be a feasible option.  This is quite different from what we should do in the relatively near future if we mess up our environment.

The sun won't be "gone." After the red giant phase, it will become a white dwarf and cool slowly over an immense period of time.  The earth will cool back down, but it will have no atmosphere or water.  It will be like the moon or Mercury.

Answer 4

Not here on Earth!!! One way or another, the Sun is the source of all energy and vegatable and animal life on this planet. If the sun is "gone" by burning out, life here will disappear. If it "goes" by being destroyed by a giant, invading celestial body, the Earth could be sent away on a journey through space to be captured or tethered to another body that probably could not sustain human life, even if anyone survived the harrowing trip. And, our other sister planets (e.g., Mercury, Venus, Mars, etc.) would also be footnotes in the astronomic history of the universe, if anybody somewhere else is taking stock.

Answer 5

After another 4 billion years of evolution I don't think you'd recognize them as "people".  And if they haven't learned how to move to another star by then, they don't deserve to survive.

Answer 6

No.  The Sun is the center of all life and existence on Earth (not to mention God if you're religious), and without it, the Solar System would not exist.

The Sun is approximately 5 billion years old.  Its life expectancy is 10 billion years.  Therefore, it has about 5 billion years until death.  When it dies, it will expand, becoming less and less dense.  It will grow much larger than the outer reaches of the Solar System, engulfing all the planets, and even Pluto.

Then it will explode.  It will not create a supernova, like large stars produce.  The Sun is only a medium-sized star.  Scientists believe that it will explode, then draw matter and energy back in to create a new star.

Anyhow, I don't think humans (or any life) will exist on Earth in 5 billion years.

I hope I answered your question.

Answer 7

What do you mean - when the sun is gone

It won;t just go away...

Anyway - as it dies it will become a red giant twice.

First time it will scorch the earth and the second time it will swallow it.

After that it will shrink to a white dwarf and slowly cool over billions of years.

I think we can safely say that there won;t be anything living on earth by then...

Answer 8

No.  That would be in about 5 billion years.  The entirety of all mulit-cellular evolution is only about 600 million years old.  The genus Homo is only 4 million years old.

There will be no people around at all.

Answer 9

No, cause its gonna blow up
