when and why will the earth explode?

Question

why will it explode?

Answer 1

brilliant jirstan2!

The Sun does not have enough mass to explode as a supernova. Instead, in 4-5 billion years, it will enter a red giant phase, its outer layers expanding as the hydrogen fuel in the core is consumed and the core contracts and heats up. Helium fusion will begin when the core temperature reaches around 100 MK, and will produce carbon and oxygen. 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. However, Earth's water will be boiled away and most of its atmosphere will escape into space.

Following the red giant phase, intense thermal pulsations will cause the Sun to throw off its outer layers, forming a planetary nebula. The only object that will remain after the outer layers are ejected is the extremely hot stellar core, which will slowly cool and fade as a white dwarf over many billions of years. This stellar evolution scenario is typical of low- to medium-mass stars.

Answer 2

The Earth has not exploded in 4.5 billion years, what idiot has put it in your mind that it will any time soon.

When we talk about destroying the earth, we really mean the biospher in which we live. That is a skin on the earth, relatively thinner than the skin on an apple. Take the skin off an apple and you still have a good apple to eat.

The solid Earth is over a million times the mass of the biosphere.

The solid earth is 20 TRILLION times the mass of all the people living on it.

The solid Earth will survive anything but the end of the sun, which will not happen for billions of years.

Answer 3

Why would you think the earth is going to explode?I don't think it is going to explode, maybe a meteorite will hit in 2012 and cause a lot of damage but explode? Maybe ??

Answer 4

The earth will never explode,unless it is impacted by a giant meteor,other wise it will eventually be vaporized by the expanding sun.

Answer 5

Jan. 24th, 4033 !! Sorry, if Jan. 24th is your
birthday. But you will not be alive anymore anyway.

The earth's core will simply combust !

P.S. -

everyone will have their theory, but there is no correct answer, only theories. And the religious speculations given from the people who share belief in a god, the god-concept which is fear
driven, those opinions are definately far from
being correct.

Answer 6

when bin laden gives the order
nah just kidding the earths temperature is rising due to the pollution & nuclear wastes so it's temp will keep rising wich causes plauges and deah of many creatures and is belived to explode in the end so in a couple of thoused years or so

Answer 7

well it's so far irrelavent when the earth will explode, but all we knwo is it will happen. but hwen is the question, if it explodes tomorrow well it did, but the reason why it happens is purely because the earths core will expand and eventually cause it to rupture, ( think of how the earth was created) the beginning is the end

Answer 8

wont explode, will be wiped out by us in the next 12 years, then crustacians will have reign for a few hundred thousand years, finally a solar flare will take out the remainder of life, all but microbes .

Answer 9

About 5 billion years from now when the sun goes super-nova.

Answer 10

in 5 to 5.5 billion years. the sun will begin to cool down and in the process swell up and burn everything on the planet before it eventually absorbs it.
