When Will The World End And How?

Question

When Will The World End And How?

Answer 1

our school room. This does not mean that we are incapable of destroying most of what is here so we have to go back to a more basic time. We've done it before. There was a time when we were even farther along than we are now, as far as technology is concerned. Hopefully there are enough of us that want to preserve what we have gained so far. The peace that will allow for this begins with each individual. It is up to each of us to decide whether we are part of the problem or part of the solution.
and i think that until 4.5 billion years later human will find a new galaxy for living :)

Answer 2

The sun is 93,000,000 million miles away from us and there are these things called Solar Flares and Solar Storms that flare up and shoot out from Solar Spots. Well the end of the world is going to be on Dec. 21st 2012. The sun will be at it's "solar maximum" an 11 year cycle where the most chaotic solar flares pop up. Also, the Mayan calender ends on that date, it will also be the December solstice.

So when the solar flare hits and breaks through the magnetic shield around Earth, the same type of thing that causes the Aura Borealis but a thousand times greater, will short out every circuit on Earth, also igniting wild fires every where. Cell phones? TV signals? Forget about it! back to the dark ages.

It's going to be pande-freakin-monium.

Answer 3

Humans have been around for about 200,000 years and they are rather adaptable. Who knows how long they are good for.

All sorts of bad things can happen that would destroy human life: a really really bad disease, a large meteor or comet impact, a passing rogue star or planet tearing our planet out of its orbit, a gamma ray burster, a nearby supernova.. all sort of things. None of them very likely. Of course given enough time even unlikely events can happen.

Much sooner than the 4.5 billion years that people quote about the sun going red-giant all life on earth will be long dead. The sun is getting brighter. slowly. In anywhere from 100 million years to 900 million years all life will be dead. Life is already in decline.

There is a wonderful book entitled "The life and death of planet earth" by ward and brownlee and details why this is going to happen. It is very readable.

Actually earth might survive the suns red giant stage. It will still be lifeless and seriously scorched, but a lot of authorities insist that the size of the sun will NOT be large enough to reach earth's orbit. So when the sun finally collapses into a white dwarf, earth will be there: a frozen sphere of rock, orbiting the old star for eternity with no sign humanity ever existed. Now doesn't that make you feel good?

Answer 4

depends on what you mean by "end". If the planet manages to not end up in a massive collision with another object forever, and manages to survive the expansion of the sun in a few billion years, the rocky ball we call earth might go on orbiting a dead ember of a star for trillions of years.

If you mean will "our" world end, that's pretty much up to us and whether we can keep from blowing ourselves up or unleashing a 100% fatal virus plague on ourselves. But a six mile wide asteroid striking the planet would pretty much do us in as well. The planet would still be here, but our "world" would be gone. That's why we have to get off this planet and on to as many others as possible. Right now, all our eggs are in this one basket.

Answer 5

In about 4.5 billion years our sun will exhaust its supply of hydrogen and will expand into a red giant. It will be so large that it will probably extend out to earth's orbit and swallow the planet up.

When this happens, earth will be destroyed. Humans, provided we're still on earth and haven't figured out a way to leave the planet, will die.

However, this is assuming that we humans don't destroy the planet ourselves in the meantime. If I were placing bets, I'd say we'd destroy it long before the sun does. But hey, I'm an optimist!

Answer 6

In about 5 billion years, the sun will run out of it's fuel - hydrogen. Typically, it'll swell up to be a red giant, engulfing Mercury, venus, and the Earth. Earth's oceans will boil away, the land will be scorched, and the contact with the solar atmosphere will slow down it's motion - and it'll fall in to the sun, becoming part of it's core.

But... we've got a while to figure out an exit strategy.

Answer 7

My guess (if we, humans, don't destroy ourselves in the meantime): when the Sun runs out of fuel and becomes a red giant.
About 5 billion years.

This is about the same time (give or take a billion years) as the collision of our Galaxy with the Andromeda galaxy.

Answer 8

I don't know when; but as to how, it will end not with a bang, but a whimper.

Answer 9

Read Matthew chapter 24 (in the bible) to see what Jesus said about it.

Answer 10

all i can say is that the answers you are looking for are in the Bible. go and read REVELATIONS. it tells you and prepares you. but in order to get a timeline or things to look for in the events to come you would need to read the whole Bible. it gives you a lot of knowledge and answers to everyday question!!
