Date: April 23rd, 2026 10:00 AM Author: Embarrassed to the bone lascivious sneaky criminal We'll discover that gravity is analagous to LOD (level of detail) in video games, where assets look and behave differently at different scales. As we find ways to expand our field and scale of view, we'll discover other LOD related artifacts of extremely large and extremely small varieties (http://www.autoadmit.com/thread.php?thread_id=5859514&forum_id=2#49836669) |

Date: April 23rd, 2026 12:14 PM Author: saffron multi-colored factory reset button you're referring to planck's constant, which was the theoretical "minimum" for the size of energy quanta until the Higgs boson was discovered in 2012. Previously, planck's constant was thought to be the "resolution" at which we observe the universe, which is analogous to LOD in video games. But now, whether something smaller than the Higgs boson exists remains an open (and fundamental) physics question. We don't know if things just keep getting smaller and smaller almost recursively (and infinitely) or if there is something even smaller that constitutes the fundamental building block of our universe.

Date: April 23rd, 2026 1:26 PM Author: saffron multi-colored factory reset button I like the duality concept here: Every particle has a "dual" -- that's what the higgs boson discovery suggested. There's some anti-gravity "dual" that we have yet to discover but probably comes into play. That's the extent of my knowledge on this topic, though.

Date: April 25th, 2026 6:07 PM Author: gaped crimson crackhouse goyim idk I think holography has resulted in some interesting research programs, I like the ones that try to reconstruct spacetime itself from "entanglement networks" and think thats a good move, but I'm not sure it will be enough.
When I look at Gravity the two things that stand out to me are the cosmological constant and the metric tensor. The cosmological constant is suspect because it was hand inserted then later removed then put back in again and it can be put on either the geometric side or mass-energy side of the equation. The thing thats interests me about the metric tensor is that it seems to be doing too much and assuming that "geometry" is the fundamental ontology and not just an effective representation. One thing especially suspect with the metric tensor is minimal coupling. It is hand inserted. It says matter fields couple to gravity only through the metric, no direct curvature coupling which is elegant but not derived. It is possible that the metric really is fundamental and gravity really is geomoetry. Or it's just a coincidence at the scale we can measure. I have more to say about this but don't feel like writing it all. A lot of it basically comes down to that there are a lot of points where geometry/smooth continuous manifolds describing "warped" space and time are suspect as fundamental vs. effective representation but basically at every leakage point we aren't quite there in terms of having the instruments to detect deviations that would prove it |

Date: April 25th, 2026 8:40 PM Author: saffron multi-colored factory reset button holography is wild. I got *really* into it as a kid and have a 60 mW HeNe laser at my parents' house that I used to create holograms in one of our bathrooms. I converted it to a dark room, built a holography table (with really expensive optical mirrors and beam splitters). It's an insane field.
I even e-mailed Stephen Benton (RIP) at the MIT Media Lab when I was 15. He e-mailed me back and gave me some pointers. |

Date: April 25th, 2026 10:13 PM Author: gaped crimson crackhouse goyim yeah it is. holography here isn't literally the same as the kind in optics that you are talking about, but oddly its not just a metaphor either. the mathematical mapping regarding the "duality" that the other poaster mentioned is basically strcuturaly isopmorphic with holograms that someone like stephen benton uses operating through electromagnetic fields, and the duality found in theoretical models like ads/cft operating through quantum entanglement. which is pretty insane when you think about it (http://www.autoadmit.com/thread.php?thread_id=5859514&forum_id=2#49843353) |

Date: April 27th, 2026 12:13 PM Author: saffron multi-colored factory reset button yeah, I knew the sense you were referring to but because it really is analogous, I thought to mention that anecdote. All of this shit is really crazy and I wish I knew more about it. (http://www.autoadmit.com/thread.php?thread_id=5859514&forum_id=2#49846639) |

Date: April 27th, 2026 12:34 PM Author: gaped crimson crackhouse goyim To me one of the biggest puzzles is how the hell "geometry" of "spacetime" and "gravitational waves" remain invariant regardless of the density of the medium. Like the intergalactic medium is so diffuse it fails to behave like a fluid at all, but we know from qft there is no true vacuum. But why do "gravitational waves" still propagate the same in that vs through the Earth's atmosphere? What is this "background"? It feels like holography is still just pushing the problem back. We went from "ether" to "spacetime" to "bulk" but it still doesn't seem satisfying even if holography fully gets figured out. It doesn't explain what the boundary or bulk are made of or what type of substrate supports them. The related entanglement picture has the same problem. Spacetime geometry emerges from entanglement. Okay. Entanglement between what? Sitting in what? I think the final version of quantum gravity should have to solve the background independence problem.

Date: April 26th, 2026 4:02 PM Author: useless brindle persian I’m a Penrose fanboy so don’t think it exists or that any of the faggots working on loop quantum gravity based on a flawed understanding of the very twisters that Penrose invented are doing anything productive. I think it’s increasingly likely that that physicists have spent the last 60 years going down a series of mathematical rabbit holes and that reality is not all that complicated. I do find it hilarious that giants like Turok won’t even touch this subject out of fear of career suicide and he’s an old who shouldn’t even be afraid but clearly is.

Date: April 26th, 2026 5:54 PM Author: avocado bossy resort Holy crap, another Penrose fan here.
If you have his two-volume work on twistors, I'm surprised you'd say something like "reality is not all that complicated." The issue is that reality is different at that scale than that in which we live. |

Date: April 27th, 2026 3:31 AM Author: gaped crimson crackhouse goyim Yeah this is what I was thinking too. I also like Penrose. Mostly because he's not a fucking pussy and will go deep into the philosophical issues unlike most fags. (http://www.autoadmit.com/thread.php?thread_id=5859514&forum_id=2#49845870) |

Date: April 27th, 2026 2:12 PM Author: Curious ruby brunch Penrose is GOAT POTUS of physics. Seemingly the only guy who has the guts to explore interesting ideas and isn't afraid of being wrong or not knowing. Compare him to a fraud like Lawrence "The Pervert" Krauss who makes claims like "the universe comes from nothing" and then defines nothing as not actually being "nothing."

Date: April 27th, 2026 2:27 PM Author: gaped crimson crackhouse goyim Yeah Penrose's early work with Hawking is unimpeachable so that pretty much makes it so he's allowed to be heterodox and call string theory a fashion and quantum mechanics "faith" and state that the foundations are wrong. Shit like that. But there should be more guys like this. Feynmann was like this too. (http://www.autoadmit.com/thread.php?thread_id=5859514&forum_id=2#49846979) |

Date: April 27th, 2026 5:16 PM Author: useless brindle persian Penrose is a math professor first and foremost and physics is like his hobby. Twistors are a mathematical masturbation of sorts but his CCC cosmology and Turok’s CPT symetry are as simple as cosmologies gets (no 26 or 200 dimensions for starters and no gravitons or anything beyond the Higgs and it isn’t even clear if they view the Higgs as fundamental or not…. It’s actually simple enough for lay people to follow even if they don’t at all understand the math unlike string theory. (http://www.autoadmit.com/thread.php?thread_id=5859514&forum_id=2#49847371) |

Date: April 27th, 2026 6:21 PM Author: gaped crimson crackhouse goyim Yeah physicists don't like that, because it looks indistinguishable from mathematics that happens to use physical vocabulary. But sometimes stuff like that is physics operating at a depth that won't be testable until the instrumentation catches up. Penrose's twistor theory and Witten's M theory could turn out to have legit parts to them. Riemann was doing pure maths that was motivated as such I mean not physically motivated at all, and ended up creating the exact language GR needed for gravity.
