scary, fun, mind-blowing
the universe we live in is really, really amazingly weird, stranger than anything that we could possibly have invented. I find it very exciting but it does mean that you can’t grasp it in its entirety.
It’s like, the world is essentially four-dimensional. We live in three dimensions of space, one of time. Einstein discovered that gravity is the warping of space-time. We can’t see it because we cannot experience four dimensions. We can only experience three dimensions. Or the “Big Bang” itself. You can’t get your head around it completely. How could it have happened everywhere at once? But it’s a four-dimensional thing so you can’t get your head around it.
