[00:00:00]Within 500 million years, you'll witness even bigger supernova threats like WR 104 out in the Sagittarius constellation, 8,000 light-years away.

[00:00:13]Once it goes supernova, the gamma radiation will pulverize our ozone layer causing extreme acid rain and set off another extinction-level event.

[00:00:26]In 1 billion years, well, things will get dark.

[00:00:31]Not not visually dark.

[00:00:32]>> [music] >> Visually, it'll be quite the opposite.

[00:00:35]The Sun will start emitting more energy than ever and that will make Earth's temperature go way up. All that excess solar energy will interrupt the carbon cycle, kill photosynthesis, and cause oxygen levels in the atmosphere to drop.

[00:00:53]No plants, more problems.

[00:00:56]If anything were still alive on Earth at this point, well, it won't be for long.

[00:01:01]Most oxygen-breathing life on the planet will have died out. Only anaerobic creatures will survive for a while. And those are organisms that live and grow in environments [music] without oxygen.

[00:01:15]As our planet is going through this atmospheric change, you'll have to leave [music] Earth behind or move it to a different orbit if you still know how to do that, old trick.
