Well, not quite. I currently aim to be and am studying, buuuuut I’m not technically getting paid yet :q
But I am studying directly under a Ph.D advisor for undergraduate research, and I’ve been there for a lot of work, and have studied all the stuff seriously for years and years…

Depends on the density.
Basically, adding mass in a volume of space causes space to curve positively. Imagine it’s like setting weight on a rubber sheet and the sheet warps, right?
But the expansion of the universe means space intrinsically likes to bow up like it’s being inflated a little from below in that mental image, so if you add a little bit of weight everywhere you could flatten it out.
But if you don’t add enough, it will stay bowed up.
Eh, I’ll get into more detail in a few hours, I need to catch a little sleep first, but basically, the universe can have infinite energy, no problem. Not sure about infinite energy at a single point, but infinite energy, still, as long as it’s spread over a finite density. And even if the density is great enough to make the universe positively curved, that’s just a “big crunch”, which is literally just a big bang played in reverse and no more or less mysterious in terms of all the singularity questions.
But I think how it got there is important, too? Hmm. That actually gets me thinking in a good way.
@Darth Sonic
But basically, infinite black holes forming at every point in the universe and swallowing it is exactly what the big bang was, but in reverse.
The big bang didn’t originate at any particular point, it happened everywhere at once, and the universe didn’t expand out from any particular point, it just got bigger from being infinitely small.
Or, almost infinitely small. Once you get to quantum scales is where things get hazy.
Edited
I don’t think you quite got his meaning. If the were infinite photons throughout the whole universe, there would be infinite black holes formed that would eat the universe.
Definitely not. I mean Cirrus, one of our most prolific posters, is a professional physicist.
It wouldn’t destroy the universe, it’d just create a black hole. Singularities break our understanding of physics, but the universe seems to exist just fine, anyways, and there are plenty of them out there, so doubtlessly it’s just our lack of understanding. Which makes sense since they’re quantum things and General Relativity - the extremely successful theory of gravity that predicts singularities - is not compatible with Quantum Mechanics.
Also, fun fact; singularities have nothing to do with mass - not alone, anyways - but according to general relativity their formation is inevitable if you get a certain amount of energy in a certain region - ie, achieve a certain density, and the greater the mass, the lower that density has to be (you can’t take that principle to the size of the whole universe, though, because the universe is expanding and that messes with that).
The theoretical limit of information, though, you’re right, is finite, but extremely huge.
I doubt human eyes operate anywhere near that limit, because it’s pretty insane and doesn’t take realistic complexities into account.
But I do recall hearing that human eyes see around 30 FPS and once you get above 8k, there’s really no perceptible difference. The quality of your vision is drastically lower than all the physical information present. Case in point; if you’re looking at your screen right now and suddenly 10 photons shift, you don’t have any friggin hope of noticing.
Interestingly enough, though, apparently frog eyes are sensitive enough to detect individual photons… Random odd tidbit. I doubt they could manage all the information of trillions of them, though. That’s more than the number of neurons in their brain, so…
But if you have them in a completely dark environment and shine individual photons on their eyes, apparently there’s some neural activity or they notice at some level or something.

“Science in the comments” tag. I hope it’s still around. I’m on this site, so it’s not real surprise that tag exists XD

that might be a first.
The amount of energy in the universe is finite, therefore there can’t exist an infinite number of photons. Even if we were to assume there are infinite photons, photons have energy and energy warps space-time. If an infinite number of photons were to occupy an infinitesimal amount of space, it would create a massive singularity that destroys the universe.
It would be more practical to say, the universe has a (very large) resolution and (very high) fps.
I think speed of light caps input/output response speed, not FPS
FPS would be capped by how many photons can fit into a space and therefore can reach a display device within x amount of time; I’m unsure if there’s a limit to this since photons don’t have mass
Resolution is theoretically capped by how close together atoms can be, which is definitely a thing due to the Strong Nuclear Force… but the amount of atoms you can see if you look at a brick wall is a really really big number
the only limiting factor is how good your eyes are. how far can you see? how much detail can you see? but that doesn’t change what’s being rendered. the graphical processing and the display device are not the same thing
i stand by a really big number p and ∞fps

I’m pretty sure FPS are capped by the speed of light. I’m also pretty sure maximum resolution is also capped by the number of photons that hit your receiver. In short, neither resolution or fps are infinite due to the limitations of photons.
50FPS!?
How dare you insult God’s hardware like that
He’s spent more money than what currently exists in the universe to build his rig
I mean have you gone outside lately?
have you seen that texture quality? holy shit
Edited
Funny enough it always felt like 50fps to me.
Real life runs at ∞p and ∞fps
your eyes just need to have the hardware to perceive it
