Interesting Physics pics.
The first point was what I used to read in text books when I was young.
Then Hawking radiation stepped in during early 90s.
Everyone sees a different reality as per Quantum Mechanics.
Every star we see in the sky is in this small part of our Galaxy. The rest, we see as a white cloud, the milky way.
Note, this Galaxy is not the entire Universe. Just one galaxy out of billions.
In real life, we don't really need to know about a lot of things.
So stop glancing at the clock.
