What Planet Earth Will Look Like In The Future (5 pics)
In 600 million years the sun will have caused so much carbon dioxide to be trapped in Earth's crust that photosynthesis will cease says Hanson, leading to all multicellular life being eradicated. By the billion-year mark, all oceans and life will have disappeared from the surface of Earth, leaving it looking somewhat like Mars
In four billion years our Milky Way will collide with the Andromeda galaxy but, owing to the huge spaces between stars, it is unlikely many collisions will occur. In fact, it's possible that only six out of a total of a trillion stars will hit each other
In 7.9 billion years, when our sun runs out of gas, it starts to expand and consumers the inner planets Mercury and Venus before deflating into a white dwarf 1.6 billion years later
In 110 trillion years all stars will have died out while in a quadrillion years our planet, now a lifeless hunk of rock, will fall into what is left of the sun (now a black dwarf) as its orbit decays
Ultimately the universe will continue to expand until everything in it is dead. All matter will be so spread out than, in essence, nothing will remain and the cosmos will be completely empty, says Hanson
