How masses bend our Universe? (Patreon)

If SR(Special Relativity)is about moving trains and cleavage, GR(General Relativity) is when the train itself bends under the weight of your ass.

Here everything bends, both space and time.

Einstein looked at Newton’s gravity (masses attract because… well, just because, don’t fuck my brain in the morning)
and said:
No, guys, masses don’t attract, masses BEND.

Imagine a trampoline. You put a kettlebell on it and the fabric sags. You throw a tennis ball next to it and it rolls not because the kettlebell “sucked it in”, but because the fabric is now curved.

In the real world instead of fabric it is space-time itself, and instead of the kettlebell it is a planet, a star or you after three pieces of cake or a couple of beers.

The main feature of GR:
Mass and energy tell space-time how to curve.
Space-time tells masses how to move.
Fuck, these dumb physicists really insane…

And here start effects that SR couldn’t even dream of:

Light bends (gravitational lensing)

Time runs slower where gravity is stronger (clocks at the bottom of a mine run slower than those at the top of a mountain)

And you already know about black holes and spaghettification.

Wanna post about gravitational lensing?
I'd love!
