last theory i heard was that in 250 million yrs. the earth will be swallowed by the sun..my question is?

Question

i wonder how long before it is actually swallowed by the sun will life on earth cease to exist?

Answer 1

The people who said it is closer to 4.5 to 5 *billion* years, are correct.

The sun is a class G star, which has a lifespan of about 10 billion years (the main part of it's lifespan ... after 10 billion years, it expands and goes through a second, larger but shorter-lived phase). The sun is about 4.5 to 5 billion years old, which means that it's about halfway through its main lifespan. So it will be here a little bit more than it has been here already ... which is a *very* long time.

If the earth hasn't been physically destroyed by an asteroid, or some man-made catastrophe we cannot imagine yet, I am quite sure that life will still be going strong on the earth at that time .. but that humans will be long gone. Either we will have left after making the planet uninhabitable for ourselves, or we will have killed each other off, or we will go extinct through natural causes (like an asteroid that doesn't destroy the planet, but does wipe out most life). But in all cases, some life forms will survive, and will do quite fine without us.

Even if we blew each other to pieces with nuclear weapons, and wiped out almost all life on the planet due to radiation, some life would survive the radiation (e.g. in the deep oceans) and life would eventually bounce back ... and would begin the process of evolution all over again. That's what life does.

Answer 2

I'm not saying to know an exact date, nobody is entirely sure as to when the Sun will "swallow the Earth", but it is much closer to 4.5 billion years, not 250 million (I'm assuming that they've estimated the amount of hydrogen and helium that's in the Sun and then applied a formula for decay). When one wonders about something, it's not really a question...but...I would assume that life won't cease to exist on Earth until the Sun does run out of fuel. It won't create a supernova, our star is not large enough, but it is predicted to "swallow" Mars as well as the other three rocky planets, the gaseous ones being much too far away for the sun to ever touch. I'm not saying that we, as humans, will be alive, we will most likely be long gone before the Sun even thinks of dieing, but the "lower" (more highly evolved organisms such as cockroaches) will most likely be there...but then again, who knows for sure?

Answer 3

About 5 billion years from now the sun will swell to a red giant. It will get so big that it will swallow the earth. Basically everything on earth is going to get vaporized.

So yes to the last part of your question, and no to the first part. It will take 5 or so billion years, not 250 million years.

Answer 4

Let me translate what your asking:

"I have been told that in 2.5 billion years, the Sun will grow so large, that the Earth (and the other planets) will burn up and no life will cease to exist. Is this true?"

Yes, it is 100% true. Scientists are still trying to figure out if the Sun increasing it's size has anything to do with global warming. Interesting, huh?

Answer 5

In 2.5 billion years the sun will grow into a giant star and
swallow the inner planets

Answer 6

the most the fossil list shows us is even as any geological era ended. It says not some thing about it is beginning or how lengthy it existed. The fossil list really isn't some thing yet a series of snapshots (20 or 30) masking about 4 billion years. some thing between those snapshots is inferred in accordance with really some assumptions and many different issues could only as honestly be inferred with a diverse set of assumptions. utilizing a similar data you do enable me make some inferences. The fossil list files the actual actuality the earth replaced into created, destroyed and reformed many cases. After each and each and every reformation those creatures that were valuable were restored to boot as new creatures and issues we left to run for a lengthy time period to ascertain what occurs. After billions of years and 20 or 30 reformations each and each and every of the plausible variables and configurations were performed out and utilizing that suggestion God did one extra reformation that represents the perfect plausible configuration for his applications. that's even plausible that God used evolution as a mechanism in previous epochs to run issues through his eventualities. After operating his eventualities and determining the perfect plausible project God grew to develop into evolution off. (that would clarify why in spite of better than one hundred and fifty years of searching there is not one case of without delay ahead descent being observed in nature or shown experimentally) i'm not putting forward that is what honestly occurred, even though it is really as potential in mild of the data as your eventualities - that's likewise not in any respect incompatible with the Bible which extremely states in Genesis 2:2 that the earth has had better than one era. the point is once you're making arguments about the historic previous of the earth depending on the fossil list you're literally not arguing utilizing data, you're arguing inference in accordance with unproven and constructive unprovable assumptions.. if truth be told are are arguing imaginary activities and calling them data -- that respectfully, is somewhat delusional!

Answer 7

The scitist said that in one hundred billion years the sun will expand that could the part of bible when it said that it will fall fire from the sky but nobopdy knows when will be the end of the world. well good luck with what ever it is that u wana know

Answer 8

i think another 3 billion years, you will die before the sun destroys the earth. the sun goes through a process called supernova, (get superhuge) blow up and swallow the earth in.

Answer 9

umm you heard wrong, not in 250 million years.

you are off by an order of magnitude
maybe 2.5 billion years

and who can say what will happen by then

will we colonize other planets, other stars? will we have evolved
into other beings by then? any answer is just a guess

Answer 10

Yeah I agree with the first answerer. We are way too stupid to avoid killing ourselves off long before it happens. So, why worry?
