Question

How long life on earth is going to exist? Justifications?

Answer 1

Until the Sun goes super nova.

Answer 2

i dono but by the way people are acting not laong

Answer 3

Life on earth has moved into some very extreme environments. Boiling water vents, extreme cold, not sunlight, many miles deep in the earth. It seems to me that life has adapted to every area on the globe and will continue to do so. Spores have been predicted to be able to survive in the high radiation and vacuum of space. My conclusion is that life will persist on earth until the earth is enveloped by the sun billions on years from now.

Answer 4

Forever.  As long as the earth is here.  Life is here.  Germs are life, bugs are life.  Unless the earth blows up and disintegrates there will always be some form of life here.

Answer 5

if you really think about it, the life could never end.  The sun will get larger, and make the surface uninhabtable for terrestrial animals again most likely, but I bet there will always be some sort of microscopic life that will survive.  The reason I said this is because comets are made of organic material/ice.  And scientists have found out there are many microorganisms that can survive in ice, survive in a vacuum, survive in no gravity.  They could be protected from uv, and other damaging rays, but I think its possible that life on this planet could end up somewhere else, or elsewhere in time.  For all we know, that could be how life got to this planet in the first place.  Or atleast just virus's, since they have the least in common with the rest of the other animal kingdoms.

Answer 6

define life? because "life" will always be on earth yet it be microscopic or 1000 feet tall. "life" will be on earth till earth explodes

Answer 7

The sun has fuel for about 4 billion more years. However, life on the surface of the earth will come to an end in one just billion years. It may sound Adams Familyish but we own a lot (perhaps everything) to our moon. It’s earth gyroscope. It’s what causes the earth to tip and tilt and gives us our seasons. It’s why our environment is relatively gentle compared to other planets. The gentleness it has created has caused biological evolution to flourish to the utmost.

The moon moves away from the earth about an inch and a quarter per year. In a billion years its gravitational influence will be gone. The earth will be subject to the tugs of other influences causing it to roll this way and that, helter-skelter. There will no longer be an equator or poles. Violent storms will cover the globe 24/7. Only the creatures of the deep such as those bio-luminous creatures we see on Nova or National Geographic will have any peace.

Answer 8

Human life, or all life?

I imagine there will always be SOME form of life, even if it's just a few bacteria swimming around, until our sun either goes supernova, or our planet's interior mantle and core cools enough to solidify.  If either one of those events happens (and they will, after billions more years), it's 'game over.'

Answer 9

Its only God knowes :-)

Answer 10

Until some nation pushes the nuke button, and then it will be all over.
