I’m always captured by the concept of “observable universe”, and how in a sense what’s inside of the event horizon is no longer a part of our universe, same as how things far enough away to red shift past the speed of light are no longer part of our universe. Kinda spooky. There are trips that even light isn’t fast enough to make, even with infinite time.
