when will the earth blow up?

Answer 1

First, who told you that it would blow up or did you come up with this yourself?

Second, it will never "blow up". It can be melted by an expanding Sun in a few billion years or smashed by an extremely large UNKNOWN Solar system body that crosses Earth's orbit (as of now, nothing large enough to shatter the Earth does this). That's about it for mega-disasters.

Answer 2

No. There is absolutely no mechanism by which a planet could explode. It wont happen. During the Red Giant expansion of the sun in about 5BY the sun might engulf the earth. The atmosphere of the sun may cause the moons orbit to decay and for the moon to strike the earth. Earths orbit could decay and the earth could spiral into the sun.. If it doesn't get destroyed then, it will happen several billion years later when the sun will eject serious quantities of stuff during its death throes, just before it collapses into a white dwarf. Some people have mentioned gamma ray bursters.
Since they are very short lived phenomena, only one half of the world will be sterilized: the side facing the burster. The other side should survive. Of course with the climatic disruptions that would probably result, they might not want to.

Answer 3

No, the Earth will not blow up.
The end of the Earth could happen in 2 ways.
The sun will eventually become a red giant in roughly 4.5 billion years, move closer to Earth's orbit, earth will become so hot even the oceans will dry and then there will be an end to life.
or
Life on earth could be destroyed by a gamma ray burst from about 100 light years away... all life on earth will be destroyed as the earth receives 100 times a fatal dose of radiation, tsunamis, cyclones occur and the ozone layer disappears

Answer 4

Never

It will either be melted when the sun starts to die and expand into a Red Star or it will be tossed out of its current orbit when the Andromdea Galaxy collides with us. But neither will happen in several billion years so you don't have to worry about it.

The earth is like a basketball only instead of air it is full of molten rock. The crust we know and love is only a few miles thick and we float on top of the molten rock like thin ice on a newly frozen pond. As the earth ages it cools and becomes more stable. At some point it will cool off and solidify entirely, but again not for a very long time. The radioactive elements in our core helps to keep it molten as does the gravitional force on the earth caused by the moon and the sun.

Answer 5

I hear some of the cosmologists saying that the Big Rip theory calls for the Earth to blow up in 20 billion years. I don't believe it, myself. But it depends on whether the acceleration of galaxies due to the expansion of the universe is constant, or whether the acceleration is increasing with time.

If the acceleration is constant, then the standard cosmology is correct, which calls for all galaxies not gravitationally bound in the same system to redshift to flatline, 0 Hz, eventually. Most of the stuff in the universe will, from our point of view, recede behind an event horizon and become invisible because their light won't go fast enough to catch up to us any more.

However, if the Big Rip theory is right, not only is there an event horizon beyond which the distant galaxies will eventually go, furthermore this event horizon itself will start closing in on locality. The volume which we call the "observable universe" will not remain constant, as with the standard cosmology, but will instead get smaller, and smaller, and smaller... until it starts getting so ridiculously small that the inverted event horizon excludes everything from everything else.

That means that matter will be pulled apart in exactly the same manner that happens inside a black hole. The Big Rip theory calls for the Earth to explode about 30 minutes before the atoms are pulled apart, about 20 billion years from now.

The Big Rip theorists might, of course, be wrong.

Answer 6

The earth isn't technically going to blow up. What will happen will happen in about 4.5 billion years. The sun will stop fusing 4 hydrogen atoms into 1 helium atom. The sun will then fuse the helium atom into carbon atoms. Once this happens, the sun will expand in size and eventually consume the earth. Even before the sun reaches the earth, the earth will be scorched by the sun's heat.

Answer 7

It won't. In a few billion years, our sun will expand into a red giant and earth will likely be incinerated.
