22. This is a picture taken from the Hubble telescope. In just this space there are millions of galaxies, each and everyone of them containing million of stars, each with planets orbiting around them.
23. This is one of these galaxies, UDF 423. It’s 10 billion light years away. Do you know what this means? Its light takes 10 billion years to reach the Earth. Basically, by looking at this galaxy you are looking 10 billion years into the past!
25. But it’s not all roses out there. Here is a black hole compared to our orbit. A black hole is a region of spacetime where gravity is so strong that no particle or light ray entering that region can ever escape from it.
So whenever you think about your life and existence, about the good and bad in this world, keep in mind that we are just a tiny, little dot lost in space. Just a little recap. This is where we live.

And here we are, here is the observable universe. Everything we said before fits in that little red dot. Impressive, right?

Thinking about how tiny and insignificant we are compared to the universe totally blew my mind. Share this with your friends!
