Simple and funny.
Scientists from the University of Colorado Boulder (go Buffs) have created a video journey of what it would look like if you fell into a black hole. I can’t even believe that people can figure this out. How do they do that? I think it’s amazing that people can figure out things like How Much Does The Earth Weigh? (6.6 sextillion tons – 2 6s followed by twenty 0s.) How do they know this? (and thank you internet for making that so easy for me to find out.)
As you approach, a dark circle is bitten out of the galaxy containing the black hole, marking the event horizon – the point beyond which nothing can escape the black hole’s grip. Light from stars directly behind the hole is swallowed by the horizon, while light from other stars is merely bent by the black hole’s gravity, forming a warped image around the hole.
