Short version as I understand it (and help me physics majors) --

Time can flow at different speeds in different parts of the universe at high speeds or under intense gravitation forces. Speeds and forces that can be imagined by physicists in equations and observed in the cosmology of the universe, but not speeds and forces that ordinary humans on Earth ever experience.

Why would time flow at different speeds under different circumstances? That's beyond me.
If you replace cosmology with cosmetology that paragraph is more entertaining.


Also, thanks for the explanation.

Time creeps along if you're a kid waiting for Christmas, or on a Friday before a big weekend, but speeds by faster and faster as you get older, all in the same universe.

So there's that theory of relativity....

Time moves along just fine most days, but then seems to drag on for eternity at the in-laws during the holidays.

That's the theory of relatives.

As i understand it (i'm not a physicist) time is essentially a *measurement of the procession of events*. When the force of gravity upon something is greater, it's "event" proceeds slower when every other variable is standardized, relative to if the force of gravity were lesser. Therefore, time moves relatively slower under greater gravitational forces. Which is why in a black hole, where gravitational force is basically infinitized, time cannot exist, because no amount of energy can break that gravitational pull thereby allowing any event to proceed

Pretty sure Nihilist Arby's twitter account stated this years ago.

If you cross the event horizon of a black hole, time and space are reversed, so you can move in any direction in time but can only go one way spatially. That's a ******* trip.

I can't tell if it's a true quote (probably not) but I like that almost as much as the one from Einstein

"Put your hand on a hot stove for a minute and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute."

And if that pretty girls sits on you, it probably will be less than a minute.

This is where I get extra confused. I can see how you travel forward in time (don't ask me to do the math) but I don't see how you can travel back in time.

Silly, you need a flux capacitor.
I lost mine.

Time as we base it, is useless/wasted….For example- EDT, CST .,,,
