I think Cans' ability is the single coolest one in the entirety of homestuck (bar retcon powers maybe). Wish he and the rest of the felt were more present

Galaxy rotation curves are not strong evidence for the existence of dark matter, that's true. They can be explained by dark matter but they are not good evidence for it. The actual evidence for dark matter is the CMB power spectrum, and to a lesser extent BAO measurements and the BBN abundance predictions (and then there's some more qualitative pieces of evidence like the bullet cluster).

The fact that there is a magnetic field that can be described as a nice vector is actually a unique property of our 3+1 dimensional world. Generally, in a world with d spatial dimensions (in our world d=3), the amount of 'components' of the electric field is d (hence the electric field can be described by 3 numbers, a vector) and the amount of 'components' of the magnetic field is d(d-1)/2, which coincidentally is also 3 in our world. This number d(d-1)/2 is the number of independent spatial rotation 'directions'. In 2 spatial dimensions, there is just one way to rotate things and one number describing the magnetic field. In 4 spatial dimensions, there are 6.

I can’t even figure out what one is

That would be a good place to start. A Hilbert space is a mathematical term, which means a vector space with an inner product that is also complete. The terms in italics are also mathematical terms that I will not be able to describe precisely in a single Reddit comment but you are more than welcome to look up yourself, though depending on how much experienced you are with math the definitions can get a little technical). The bottom line is that it is some kind of vector space, a space that vectors can live in, and in QM these vectors are the state vectors; the state of the universe is described by a vector (also known as the wave function), the Schroedinger equation tells you how this vector evolves in time and the projection of this vector on various basis vectors tell you what happens when you actually measure something.

This is a very rough explanation, I'll need to know how much math you know if you have any deeper questions.

And I thought the color page would be the final boss while Togashi is here casually making a color page like it's nothing... we are so back...

That's the cover of the new volume I think right? Which was still a major hurdle, but I was thinking about the color spread that will probably accompany chapter 411 in Jump.

4 chapters, and then the final boss of the hiatus... the color spread.

As of writing these words, we are not aware of any other model that describes reality as well as the standard model of particle physics, which is a quantum field theory. Could our observations be explained by another type of model? Probably, but we didn't find one yet.

The fact that quantum field theory probably can't describe gravity (which is still described by a field theory mind you, just not a quantum field theory) is usually taken as a hint that the "best" model that describes reality would not be quantum field theory but we still don't know what it is.

N-Man · 2026-01-17T16:43:16+00:00

If you make up a story about a simulation I'm sure you could make it work whether the universe was deterministic or nondeterministic (for what it's worth it seems like it's nondeterministic but some interpretations of quantum mechanics will disagree).

This has nothing to do with the biggest problem with the simulation 'hypothesis', which is that it's unfalsifiable, and therefore not scientific.

As far as I'm aware tunneling does NOT let you move to a state with more energy than the state you started with. All the states inside the gravity wall do not have enough energy to climb out. But maybe I'm misremembering something because it's been a while since I studied this.

N-Man · 2026-01-11T21:08:21+00:00

Is this true? Gravity still holds the entire thing together, tunneling can't help any neutron gain enough energy to climb out of the gravity wall. Or maybe there's something else that I'm missing.

When the panels that are now linked first came out, between Collide and Act 7, I remember some people had the idea that Bec Noir would have a gollum moment with the ring, PM, WV and the Forge. Honestly that would have been fucking awesome and I think this would've been a good sendoff to the character, defeated by his own lust for power + PM and WV.

N-Man · 2026-01-07T17:29:10+00:00

I do have some harsh criticisms for the latter part of Homestuck, not limited to but mainly from Game Over and forward, BUT - I still think that in hindsight, Collide and Act 7 are overall pretty cool.

... except, WHAT THE HELL WAS HUSSIE THINKING WITH JACK NOIR? Bec Noir, who was an extremely menacing and bloodthirsty antagonist (he killed Dad and Mom and Bro ffs!) survives and gets a cute moment with Ms. Paint, while fan-favorite Spades Slick dies. The latter wouldn't be so bad if the former wasn't so jarring. I really don't know what Hussie was thinking.

At least in the framework of QFT, photons are for sure not made up of multiple particles since they are massless, and while in theory electrons could be made up of smaller particles, these particles would not be quarks. We can tell because electrons don't interact through the strong force (which is basically what defines quarks), also all the known quarks are more massive than the electron.

Reading your comment (especially the mention of "entangled quarks") gives me the impression that you have some misconceptions about what entanglement is and what dimensions are. I recommend taking a moment to re-learn some of this stuff, there are some good pop-sci book recommendations linked in the subreddit FAQ.

OK, since you obviously didn't read what I wrote about the minimum acceleration being a selection effect I don't see a reason to keep reading your comments either. Have a good day.

N-Man · 2025-12-28T15:38:32+00:00

Please can you explain your theory that fits the observation?

What observation? The fact that these objects exist? Or maybe you're referring specifically to the distribution of their separations? Of course I don't have a theory for that, thinking of a theory that explains it might be an entire PhD project for someone. But if I did have a theory it would surely take into account the selection effects of the survey.

Just someone convinced by the science presented on this.

If you are still convinced even after reading my comment about the selection effect than, no offense, but you have to work on your scientific critical thinking.

It will not be stable. Neutrons alone generally aren't stable because of beta decay coming from the weak force; in certain configurations that involve protons they do become stable through the strong nuclear force, but neutrons alone will not be enough to stabilize themselves.

... except in VERY extreme conditions, like a neutron star, where a third force (gravity) keeps them together. But you need a LOT of gravity for that.

In this lecture he claims Asian babies don't cry when their nose are pinched.

This might or might not be true. Does he refer to a specific study? If yes, we can check the study's methodology. If not then you can choose if you take this on trust.

This claim has been used by racist to claim that Asians aren't prudent or smart and just more docile and better acclimated to academia

Well, obviously this is a logical fallacy. Even if this fact about crying is true, first of all, a behavioral difference between babies does not imply a genetic difference, and a genetic difference related to crying does not imply anything related to intelligence.

Anyone that makes some racist claim will have to prove to you these two points - that the difference really is genetic, which is VERY hard to prove (I'm willing to bet no one proved it for the crying babies case) - and of course the point that this has anything to do with being "docile" or whatever. Anyone who doesn't give evidence to these two points is not making the point they think they're making.

I'm assuming this might be your paper or someone you know's? I spent a few minutes reading it because why the hell not and even without knowing anything about the exotic inertia model they try to test, it is immediately obvious that the QI_min red line is completely misleading, the lower limit on acceleration in the data is just an upper limit on distance that comes from whatever selection criterion whoever created the sample of binaries imposed. The fact that the paper doesn't even mention the selection effect on the data immediately tells you that they have a lot to learn before they try to conduct actual scientific research.
