Death From Space
In our daily lives we might worry about getting into a car crash or having a heart attack, but suddenly getting obliterated by a far off blackhole isn't really on our radar. The universe is actually full of cosmic snipers firing off into space. In this animation, Kurzgesagt explains how gamma-ray bursts are created and what exactly would happen if one was heading for Earth. On the bright side, the possibility of one of these natural Death Stars actually hitting our planet doesn't seem too likely.
