how do u think the world will end?

Question

i thik the sun will heat it up to much and will make it explode!

Answer 1

The Sun will not make the Earth explode, but it will definitely boil away the oceans, turn the planet into a Hellish inferno like Venus is today, then drive away it's atmopshere into space and turn the surface into an ocean of lava. At this point the Sun will be a red giant with a diameter at least 100 times greater than it's current size. It's luminosity will be perhaps as much as 5,000 times as it is today, and because it will be so distended the Sun will be losing it's outer layers. If it starts to lose mass rapidly early in the red giant stages of it's life, Earth may avoid spiraling into the Sun because as it's outer layers are lost to space, the orbits or Earth and the other surviving planets will expand outwards even though Earth will be left as an airless, waterless and lifeless ball of rock and metal. If it's mass loss occurs later or at a slower rate, Earth may find itself in the Sun's outer layers. If that occurs, like a satellite dipping into the Earth's upper atmosphere Earth will rapidly spiral into the Sun's interior and vaporize. In either case, the Sun will lose half of it's mass or more, forming a planetary nebula like the Ring, Dumbell or Bug Nebula while the core collapses into the white dwarf state. No one is quite sure if Earth will survive the Sun's expansion into a red giant or not, but it will be devoid of all life long before that.

Answer 2

The Earth can't explode; there's nothing which can supply so much energy fast enough to create a planetary-sized explosion.

The "end of the earth" can mean a bunch of different things, depending.  If you are talking about the end of life on earth, that will come as the Sun heats up over the next billion years or so.  This will drive the Earth into a runaway greenhouse like Venus, where life cannot continue (too hot, no liquid water).

The end of earth the planet may never happen.  The Sun will eventually become a red giant star which will engulf Mercury and Venus, but Earth may or may not remain.  This leaves two possibilities:

1.  Earth disappears into the Sun.
2.  Earth remains as a thoroughly cooked cinder, orbiting a fading white dwarf star.

Answer 3

Engineer is right but I'd like to offer my own guess...

After people overpopulate the Earth and start a war, Jesus will come disguised as an invading alien on the same day that an asteroid and a killer comet crash into the world's nuclear arsenals setting off a chain-reaction nuclear winter and global warming effect causing the Earth to reverse poles and collide into Nibiru. This will cause the Sun to heat up and the Earth will explode.

You may be right Geoff - I need a vacation. heheh. Take over for me faesson and Efnissien.

Answer 4

Humans will die off when global warming heats the surface up too hot for us to survive. The earth will end when the sun becomes so large that the earth falls into it. The sun will eventually be a Red Giant and its radius will be larger than the earths orbit is from the center of the sun currently.

Answer 5

On Sept 30, 2008, the world will end.

It will be caused by a singularity (black hole) created by the sheer weight of points acheived in Yahoo Answers by people asking when the world will end. All these points will plunge to the center of the Earth and eat it inside out.

Most people won't even notice as they will be watching Mars, which appears nearly the size of the full Moon.

Answer 6

The world will be here long after the human race has driven itself to extinction....new species will become the dominant ones and the circle of life will continue.

that is until the sun becomes a red giant and engulfs the earth.

It's not due to happen for a while so don't worry too much :o)

Answer 7

It's been scientifically proven that in around 5 billion years, the sun will run out of fuel to sustain itself. It will expand past mars, and end up engulfing and melting half of the planets. Earth's oceans will boil away and we will cease to exist. After that, it will shrink back to its original size and most likely become a brown dwarf, no more than a few hundred kilometers in diameter.

Personally though, I believe that the human race will be long extinct by then. We will probably have nuclear winter in a few hundred years, if all goes as it is going right now.

Answer 8

I think, and this is all conjecture mind you, that the world as we know it will end shortly after November 2008, if either Hillary Clinton or Barack Obama take office after the 2008 Presidential Elections in the USA.

Answer 9

If the earth explodes, it will be some crazy scientists trying to create nuclear fusion on earth. Meaning they are trying to reach the conditions of millions of degrees celcius before they can try nuclear fusion. That is sure to make the earth blow up.

Answer 10

The "grey goo" catastrophe.
Nanobots (microscopic robots) designed to help fight cancer turn rogue following a computer virus. Instead of attacking the cancer, and using dead cancer cells to make more nanobots. They attack all organs in the body, slowly turning the infected vicim into "nanobot soup". Any doctors, nurses or anything touching the victim also get "infected", so the entire planet turns into a grey nanobot goo as it's consumed.
