Will Mankind end before the Sun expands and swallows us up in what people say 4 and 1/2 billion years.?

Question

or do you think we will be here(not us literally obviously) when that time comes?

Answer 1

The way the Earth is getting overpopulated, we'll be lucky to survive for another decade. We might as well enjoy the time we have!

Answer 2

Well there are both optimistic and pesimistic points of veiw (unless we currently have a device to see into the future) optimistic - given that the Great White Shark has survived for 350 million years and the Dinosuars have lived for about 75 million years and they had the brain the size of a peanut, human beings have yet to survive for one million years, and due to our being able to be civil and not resorting to eating one anouther we may be able to survive the next 4 and 1/2 billion years. pesimistic - with sentients came ideas on new forms of destruction such as the a-bomb and guns, given the fact that war has been a constant threw out human history, humanity may yet face the day where tools of destruction and mass destruction are used and soon face nuclear winter, nuclear poisoning, and death
although personally I believe that human life evolved in a sort of set way, an organized way thus the DNA and life which evolved on our planet may have evolved on another planet in which case man kind may exist on other planets much like atoms have a set state in our universe perhaps DNA, evolution has a similar more elaborat way motion to it thus providing the universe with centient life so even if humans don't survive the next 4.6 billion years perhaps they will elsewhere

Answer 3

The Sun will have made earth pretty much unlivable long before that. Maybe as little as one billion years. The sun itself will die in about 4.5 billion years. No matter. Our species is about 275000 years old and at the rate we are evolving a new species of humans will emerge and replace us in a few more millenia. But they too will be humans. Eventually they too, along with all mammals, will be gone. What will live on earth one billion years from now is impossible to tell. Just look at how completely alien life on earth was one billion years ago.

Answer 4

Based on the history of how long a species lasts, 4 and 1/2 billion years is an extremely long time for any species to last. I think we will be long gone by then. Replaced by some evolutionary change no one anticipated. Or we will completly disappear.

Answer 5

If mankind hasn't killed themselves, we might not be occuping the earth any longer. Everthing would have been moved to deep space or better yet, moved on to other planets in other solar systems. Humans could get into planet building where mankind would survive in mini encased self supporting planets moving through deep space in search of a young star. Several thousand small planets moving in all directions in search of a new home sun.

Answer 6

Who knows, and really why does it matter? Do you have a 4.5 billion year bond you are contemplating purchasing? Tickets for the 4.5 billion year Olympics? How will anything of that time be relevant to you right now, to include ANY human, cat, dog, polar bear, ant, whale, school, or even IDEA? Tell you what, concentrate on ways to extend peoples life spans to 1 million years, and once you are successful, then and ONLY then is that relevant.

Answer 7

I would think so. By the way, I thought it would be in 5.5 billion years? Since it takes 10 billion years for the sun's life cycle and the sun is 4.5 billion years old, it should be 5.5 billion, right?

Answer 8

I'm thinking by that time we will have alternative ways of survival that don't depend on being on earth.

Also, if I'm wrong about that, sun expansion will make the earth too hot to live on by the time the sun swallows mercury, basicly all vegetation and animals will die, and walking outside durring daylight could be fatal.

Answer 9

Probably. At the very least they will evolve into another species, probably artificially by genetic engineering, but possibly naturally too. Humans only appeared on Earth about 0.001 billion years ago. Before that it was dinosaurs or just bacteria.

Answer 10

even if we dont kill ourselves in the next 50 years, we will be a totally different species in the next million years or so, if we make it that long. Today in the news there was something on how human evolution was speeding up. Check it out

Answer 11

Yes.
A billion and a half years earlier than the red giant phase our galaxy is set to collide with the andromeda galaxy... so if a meteor doens't get us or a pole shift... then that will certainly get us.
