The author of this article has produced some very entertaining and informative videos that help make the ideas associated with string theory accessible to people like me, people who know very little about astrophysics. If you watch the first video in the article below, you may be sucked in, just like I was.

A black hole spins!
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.

I recommend that you read, or listen to, the entire poem.
When we come to it
We, this people, on this wayward, floating body
Created on this earth, of this earth
Have the power to fashion for this earth
A climate where every man and every woman
Can live freely without sanctimonious piety
Without crippling fear
When we come to it
We must confess that we are the possible
We are the miraculous, the true wonder of this world
That is when, and only when
We come to it.”

If you did not watch the video of Carl Sagan’s “Pale Blue Dot”, you can do it here.
Consider this thought. If life on earth as we know it is going to be destroyed by some extraterrestrial event some time in the future, it is possible that such an event has already happened.

“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.”
