Physicists of Lemmy, what is up?
Like what if I'm in space?

You're always in space.

Keanu Reeves woah

spun af atm
gluons be trying to keep me at home when I really wanna go out and smash
-
I'll have two of what this guy has.
-
What are you on about?
-
Subatomic particle physics I’d rather not ruin the joke by explaining it yet
-
-
-
Careful. At best, you're gonna get some armchair physicist poseurs responding to your question.
-
Yes pls
-
-
Nothing much, how about you?
-
-
The enemy gate is down, Ender!
-
Oohh this makes an excellent point!

I don't understand why people are downvoting this, but up, down, left, right all depend on your frame of reference.
Up in space is nowhere, but at the same time it is everywhere. Those are not physical concepts and they require necessarily a frame of reference to even make sense.

The up quark or u quark (symbol: u) is the lightest of all quarks, a type of elementary particle, and a significant constituent of matter. It, along with the down quark, forms the neutrons (one up quark, two down quarks) and protons ...

Nice! I didn't expect an answer I haven't even come close to pondering yet!

Down = where gravity is coming from, the most mass
Up = the opposite direction
-
What if I'm in a Lagrange point?
-

-
Ah yeah I didn't think they'd find this as amusing as others would.
-
-
Opposition of aggregate primary gravity.
-
Ok, but what if I'm between galaxies?
-
-
You need more context/specificity around your question. Right now, the question is like saying, "What is that thing...?"
-
But what is it?
-

There are some hanging out on science_memes@mander.xyz
-
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !science_memes@mander.xyz

Z axis
-
But that also has down.
-
-
The same direction it usually is relative to your perspective, assuming you're aligned to the galactic plane.

May i present to you the cosmological principle
https://en.m.wikipedia.org/wiki/Cosmological_principle
the cosmological principle is the notion that the spatial distribution of matter in the universe is uniformly isotropic when viewed on a large enough scale
So in some sense, everywhere is up
-
I was thinking up is the direction of the expansion of the universe. Not sure if this supports that or not. Or maybe since we're drawn that way, it's the opposite?
