how many years do you think the earth will last?

Answer 1

In its 4.5 billion years, Earth has evolved from its hot, violent birth to the celebrated watery blue planet that stands out in pictures from space. But in a new book, two noted University of Washington astrobiologists say the planet already has begun the long process of devolving into a burned-out cinder, eventually to be swallowed by the sun.

By their reckoning, Earth's "day in the sun" has reached 4:30 a.m., corresponding to its 4.5 billion-year age. By 5 a.m., the 1 billion-year reign of animals and plants will come to an end. At 8 a.m. the oceans will vaporize. At noon – after 12 billion years – the ever-expanding sun, transformed into a red giant, will engulf the planet, melting away any evidence it ever existed and sending molecules and atoms that once were Earth floating off into space.

Answer 2

many billions of years ,we wont be so lucky i think

the world is gonna be OK ,
climate change(Global warming) is just going to affect all that lives on the surface

but there are so many other possibilities

here is my collection of ends of the humanity


many predictions are for the years between 2012 and 2020
Nostradamus,the mayas ,Egyptians Jesus ,

and Terrance Mckennas time wave who put the magnetic output of the world into a computor projection that stopped at zero in 2012,this means the globe has stopped and it starts turning
the other way ,the resulting change of currents will turn the planet into a giant washing machine cleaning the surface

then there are the meteors storms (armageddon) ,the gulf of Mexico is the result of one that would have made life exstinct for a while ,this would result in an other ice age because globe gets covered in dust for a few years,blocking out the sun.

then there are more posible natural disasters
Volcanos are coming to life everywhere
the weather has giant storms like hurricanes ,tornados ,tidal waves ,earth quackes

a shift of the earth crust ,would change the position of the poles
under Anrarctica were found fosilized tropical plants indication the pole must have been in a different place then (the mainland atlantis is thought to be under it )

Apart from that , the biggest threat to any species of exstinction is ,when there are too little ,and when there are too many ,so overpopulation is also a threat

and the USA appears to be gunning for a global nuclear conflict .it is most likely that this will get us first ,looking at present politics

the planet will probably survive unless humanities bombs result it to be knocked out of its orbit

so many ends to choose from
if it wasnt so serious it would be rediculous

meanwhile enjoy life .and make the most of it at least we are all in the same boat

Answer 3

The earth will not wear out. The earth will end in another 5 to 7 billion years when our star comes to its end; when it does that, the sun will swell up PAST the earth's orbit, thereby incinerating everything on the earth and destroying the atmosphere. There is scientific disagreement as to whether the rocky ball of earth will remain, but the sure thing is that there will be no more life.

Answer 4

No-one really knows since all kinds of things could happen such as meteor or asteroid collision, gravitational effects from other planets and the moon is approaching Earth at the rate of a few centimetres each year and could eventually crash into our planet. The sun has a life yet of billions of years but will eventually burn out and become a black hole. There are always lots of worries about the end of the world but, really, there is no such thing, just the end of your life. After that it doesn't really matter what happens to Earth does it? Modern technology is not sufficiently advanced to enable anyone to escape but even if some craft could leave they would eventually run out of fuel before being able to reach anywhere that could sustain human life. As death is individual then any event causing it would just mean the end of your particular life.

Answer 5

The Earth is 4.5 billion years old and it is half way through its life. So, I think it would last for about 4 - 5 billion years more.

Answer 6

4.5 billion years, when Sol goes nova and destroys all the Inner planets, strips Jupiter and Saturn of their atmosphere and leave Neptune and Uranus (Outer planets) are rogue planetoids.


Additional for quatt47 -

The Moon is moving away from us, not towards.

Answer 7

either until man destoys the earth...or when the sun begins to die and expands and basically burns the earth including mercury and venus

Answer 8

I don't know and no-one can know the answer to that one exactly, but my guess is it won't last too much longer the way the world has been going.

Answer 9

The earth we be here as long as it is needed!

Answer 10

When the sun dies.
