>>16587574Years ago I once sat down for a smoke after binge watching videos about cosmology.
I tried to picture in my head if nothing were to exist. What it would be like if the universe didn't exist.
I was deep in my mind staring at noting slicing off layers of existence in my mental model until I came to the last step that was to remove the whole concept of something and BANG there it was in my mind.
The concept of nothing. It lasted a blink of an eye but I was shaken. The thought filled me with unease. It was unnatural.
Try it yourself.
