00:00These are the five scariest space facts you've been warned. If a massive asteroid was headed for

00:06the Earth, the chances are there isn't really much we could do at any moment. The Sun could emit a

00:13coronal mass ejection aimed at the Earth and if we weren't prepared for it, it could destroy the

00:19entire world's energy grid and leave us without power for years. There are black holes lurking in

00:26the shadows roaming throughout our galaxy and if one entered our solar system, it would be all over.

00:40light-years of Earth happened to emit a gamma-ray burst and it was aimed at us,

00:44the ozone layer would be destroyed. Finally, every year there is more space junk created,

00:50putting us at risk of being trapped within the Earth.
