Even if NASA doesn't recommend space travel to a black hole, the thoughtful American space agency still wants to ensure that you're safe while in space. They've created this short and fun (flight safety-style) instructional video so that if you do encounter a black hole, you're covered.
Regardless of whether or not you wish to travel to space, this is still an interesting way to learn more about what's out there and what you should expect.
The first question NASA covers in their cute video is: What is a black hole? It's made up of a minute point where gravity and density are infinite, and a line where beyond which everything (including light) can fall into that point. There's some 'stuff' orbiting around a black hole, and some radiation. Sounds inviting!
Like clothing, black holes come in different sizes — something NASA and science have yet to understand.
Surprisingly perhaps, a black hole is not, in fact, a hole. We wonder why the name was given to it in the first place. There's some mention of unicorns and space potatoes, but you'll have to watch the video to fully understand that context.
Given that the nearest black hole is 3,000 light-years away, it isn't easily reachable. However, with stars and glowing 'stuff' orbiting around them, they're relatively easy to spot.
NASA then offers safety considerations for when a black hole is found.
Check out the video to find out how to survive a black hole, if you ever encounter one.
