You're always in space.

spun af atm

gluons be trying to keep me at home when I really wanna go out and smash

What are you on about?

HootinNHollerin@lemmy.world · 4 pts · 2y

Subatomic particle physics I’d rather not ruin the joke by explaining it yet

Mango@lemmy.world · 2 pts · 2y

I'll have two of what this guy has.

LemmyKnowsBest@lemmy.world · 8 pts · 2y (1 reply)

Careful. At best, you're gonna get some armchair physicist poseurs responding to your question.

Mango@lemmy.world · 1 pts · 2y

Yes pls

Oohh this makes an excellent point!

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!

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.

Mango@lemmy.world · 1 pts · 2y (7 replies)

Ok. Frame of reference is half way between here and Andromeda!

ItsYourBoyHalo@lemmy.world · 2 pts · 2y (6 replies)

That doesn't really tell me anything, haha

Mango@lemmy.world · 0 pts · 2y (5 replies)

And I'm facing South.

ItsYourBoyHalo@lemmy.world · 1 pts · 2y (4 replies)

Dude, North, South, East and West are not real either. Again, you need a frame of reference. Those are 100% arbitrary.

Mango@lemmy.world · 0 pts · 2y (3 replies)

I can't tell if you're taking me seriously or not. 🤣

ItsYourBoyHalo@lemmy.world · 1 pts · 2y (2 replies)

I am. "Halfway" is not a frame of reference. You need to arbitrarily define what up and down is. North and South is.

Mango@lemmy.world · 0 pts · 2y

Why would it be arbitrary there? It's not arbitrary here.

Up is what you define as up in your coordinates.

Mango@lemmy.world · 0 pts · 2y (2 replies)

So up is pretend?

Ghostie21@lemmy.world · 1 pts · 2y (1 reply)

No, up is what you define as up.

Mango@lemmy.world · 0 pts · 2y

I define up as yo momma.

Down = where gravity is coming from, the most mass

Up = the opposite direction

Mango@lemmy.world · 1 pts · 2y

What if I'm in a Lagrange point?

AlwaysNowNeverNotMe@kbin.social · 3 pts · 2y (1 reply)

Opposition of aggregate primary gravity.

Mango@lemmy.world · 1 pts · 2y

Ok, but what if I'm between galaxies?

Mango@lemmy.world · 2 pts · 2y

Ah yeah I didn't think they'd find this as amusing as others would.

Hello_there@kbin.social · 2 pts · 2y (1 reply)

Z axis

Mango@lemmy.world · 1 pts · 2y

But that also has down.

Kolanaki@yiffit.net · 2 pts · 2y

The same direction it usually is relative to your perspective, assuming you're aligned to the galactic plane.

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

rivermonster@lemmy.world · 1 pts · 2y (1 reply)

You need more context/specificity around your question. Right now, the question is like saying, "What is that thing...?"

Mango@lemmy.world · 2 pts · 2y

But what is it?

aldalire@lemmy.dbzer0.com · 1 pts · 2y (1 reply)

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

Mango@lemmy.world · 1 pts · 2y

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?
