Watch the video! Young people like Katie Bouman are helping us see things that have never been seen in the past. They have now managed to obtain the first picture of a black hole! This video is from a couple of years back.

PS. I got the link for this video from a friend.
A short video well worth watching in our days of earthly turmoil.
“Albert Einstein didn’t like them.
To him, black holes were a bit of an embarrassment, as they compromised his dream of a “rational” nature, that is, natural phenomena that we could describe and quantify with the usual methods of science. According to this view, good scientific theories shouldn’t generate absurd (read: “irrational”) results.”
