when will the sun blow up and humanity will fade away?

Question

I know like in a billion years but i think they will have enough tecnolagy to move to an other planet!

Answer 1

Wow. Where to start? First, the sun will never 'blow up' as in explode in a supernova. It's too small. It'll turn into a red giant though, near the end of its life. In another 3 billion years or so!
As to humanity fading away, that's also problematic. We may evolve sooner than you suspect. Or we might become extinct within just a few million years, like most normal life forms. OR we might move out into space and only end when the last suns in the universe die out. We simply don't know.

Answer 2

The Sun will expand to a red giant in about 5 billion years. Long before that, humans will be extinct. Life has been on this planet for about 3.5billion years and more than 99,9% of all life forms that have lived are extinct. All species that were alive 100 million years ago are now extinct. There are one or two surviving genera, a few families and more orders.

It is possible that our descendents will still be alive but I doubt it. More probably other intelligent life forms will evolve after we are gone and perhaps they too will go and another will appear. This could happen many times before the Sun burns the Earth to a crisp.

Answer 3

I think the sun is forecast to die in about 5 billion years (give or take a few). The sun is not forecast to blow up, because it is not massive enough to undergo such a violent end. It will expand into a red giant (which I think would engulf the Earth), and then collapse into a white dwarf. Other demises of life on Earth:

1) Asteroid impact - an asteroid has been spotted which is projected to swing very close to earth sometime this century

2) Tidal lock - the moon will eventually slow the rotation of the earth so that an earth day will no longer be 24 hours, but will take an entire month

3) Loss of air - the atmosphere is slowly leaking; given enough time, we will lose all of our atmosphere (like mars!)

4) Nuclear - iran bombs israel, which bombs iran which convinces russia to bomb europe which convinces us to bomb russia which convince china to bomb japan.....

I'm sure there are other imaginitive endings for Earth.

Hope this helps.

Answer 4

The sun will blow up in about 4 billion years, but that's only the 7th possible cause for the extinction of humans. We're more likely to be killed off by (starting from the sixth to first) by technology taking over, super volcanoes, asteroid collision, nuclear war, pandemics, or global warming.

Answer 5

I can't believe no one got this right.

It'll happen in about 5.3 billion years. The responder that said 10 billion was sorta right, but that's 10 billion years from when it was born, not from right now.

We will start terraforming Mars within the next hundred years, in my estimation, so you're right. It's not something to worry about.

Also, it won't 'blow up'. It will just expand vastly, to the point where it very nearly contains our entire orbit.

Answer 6

Our sun will not 'explode.' It would require at least 1.5 tiimes more mass than it has. Instead in about 4.5- to 5-billion years it will expand into a red giant star, consuming Mercury, Venus, and possibly even Earth. All life will end on Earth at this time.

Answer 7

my guess...four score and 7 rounds of 77 years [roughly 539 years]...plus a healthy set of random integers to the power of 79...minus the age of your cat...and finally divided by the number of tv dinners i consumed today because of mere laziness [we'll say 4 for times sake]

...that should make the Ides o' March the day o' blowage [in an appropriate sense]...

Answer 8

Not in time enough for us to worry about it. In fact, given our rate of evolution, I think "humanity" will become as extinct as the dinosuars and replaced by something else long before the sun burns out.

Answer 9

It's supposed to happen in about 10 billion years according to scientists.

Answer 10

You don't have to worry about the sun blowing up. We will get smacked by an asteroid long before that happens.
