Physicists of Lemmy, what is up?
(lemmy.world)
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
What are you on about?
Subatomic particle physics I’d rather not ruin the joke by explaining it yet
I'll have two of what this guy has.
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.
Ok. Frame of reference is half way between here and Andromeda!
That doesn't really tell me anything, haha
And I'm facing South.
Dude, North, South, East and West are not real either. Again, you need a frame of reference. Those are 100% arbitrary.
I can't tell if you're taking me seriously or not. 🤣
I am. "Halfway" is not a frame of reference. You need to arbitrarily define what up and down is. North and South is.
Why would it be arbitrary there? It's not arbitrary here.
I highly encourage you to Google this question. You don't seem to understand what a frame of reference is. At least not in this context.
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!
Opposition of aggregate primary gravity.
Ok, but what if I'm between galaxies?
Up is what you define as up in your coordinates.
So up is pretend?
No, up is what you define as up.
I define up as yo momma.

Ah yeah I didn't think they'd find this as amusing as others would.
Down = where gravity is coming from, the most mass
Up = the opposite direction
What if I'm in a Lagrange point?
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.
You need more context/specificity around your question. Right now, the question is like saying, "What is that thing...?"
But what is it?
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?
