if you think about it the holographic principle is telling us that the universe actually running in a compressed format. There are way too many quantum states to simulate at once, so for the universe to run efficiently these states need to be compressed. The holographic principle makes this explicit: all of the information in the 3d bulk is encoded on some 2d boundary of this space. What happens when there is too much information in a small region of space and it can’t be compressed further? Boom, black hole. Neat hack universe engineers. gn

Perhaps not. The density of matter within the event horizon depends on the radius. Very large black holes have very low density. There _may_ be a region of very high density within the event horizon, but that's not something we can see.

And the big-versers just wants to increase the verses size. nostr:nevent1qqswgm0xyptlgl92j9asu04udmsf0gyqeuh0egumga2hyqczxgmeh2cpz9mhxue69uhkummnw3ezuamfdejj7q3qxtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsxpqqqqqqzughkaw

I’m not smart, but I’ve genuinely been smart enough. If you’re pursuing the line of reasoning I think you are, I’d maybe point you toward “Simulation Theory” as a recognized, mathematically formulated concept suggesting how we humans are only aspects of “Awareness” operating in a simulated reality. It’s not an internet rabbit-hole, its a genuine opening to a new theory of Being.

Peter Thiel would like to disagree. To paraphrase - Impossible to prove scenarios like these are designed to (or only serve to) cause people to give up on engaging in discovery and experiencing the wonder of our reality.

Very bizarre perspective. If anything this made me want to increase engagement of discovery and wonder of our reality. what better way to increase wonder than to reverse engineer reality to figure out how it works? I was getting chatgpt to help me understand quantum compression algorithms to see if there is any way to compress many quantum states (aka tensor networks). I even found a few papers of people thinking of these same ideas https://arxiv.org/abs/1809.10156 https://arxiv.org/abs/1904.06772

I have long said that quantum theory (as well as a humble pleb can understand it) really lends some credibility to the idea we live in a simulation. It strikes me as exactly the type of optimizations a game developer would make to optimize a game. Not looking at something? Maybe it isn’t there.

Well said. And since human understanding of math has helped us create order around such randomness it would be natural to relate to an external being’s creation using the snippets of source code we have uncovered.

It’s a neat idea but would be hard to pull off and keep consistency. It also ties in consciousness which I am not a fan of. If it is a simulation, all it seems right now is that the 3d propagation of quantum waves we see are encoded efficiently on some distant 2d boundary. Then again this is all based on AdS/CFT which isn’t even a theory of our universe (but may be close somehow), so the story could be more complicated. we’re just ants inside a giant machine that we barely understand.

Bit of a tangent, but won’t it be cool if these maths end up leading to more efficient computer storage? We’ve been copying off nature’s work for eons, so it wouldn’t surprise me. These are all cool thoughts. Black holes fascinate me. They seem to violate conservation of energy, but some of Hawking’s protégés believe they may have solved that.

I mean utilizing quantum variants of Fourier transforms lead to Shors algorithm which breaks cryptography, wouldn’t be surprised if there was clever compression techniques. Downsize is trying to build quantum algorithms is like skipping rocks on a lake and hoping the correct answer is encoded at the peaks of the wavefronts. Its hard, ive tried. quantum computer science by mermin is really good for anyone who wants to deep dive into this stuff. Some light reading.

That sounds perfect for those of us who aren’t qualified but can’t help but peek behind the curtain. I started with stuff like that with a course called “Physics for Future Presidents” that was made free online by UC Berkeley. It was supposed to be “all the physics we wish a future president would understand.” 🤣 Great class.

One analogy I like from Max Tegmark is each human is like an incredibly complex braid, one of the most complex in all the universe. More complex than super computers, stars, and any non living thing in the galaxy. Each individual visualized in space time is disparate strands of atoms that converge at conception, that weave through one’s lifetime and shoot back off into randomness as our body turns over the atoms we are composed of. Eventually the braid or rope shoots off back to complete randomness (physics) as our beings ability to attract atoms and make life ceases. Then those atoms continue on the journey through space time.

If you can deal with the sub-par production quality, this is a great primer (IIRC): https://youtu.be/GHgi6E1ECgo?si=uWSJMxSF2SLEulNZ My recollection of the argument, drastically paraphrased: 1) The most amount of “stuff” or “information” that can fit in a given volume is a black hole 2) adding more “stuff”/“information” will increase the size of the black hole 3) the counter-intuitive but mathematically sound part: in our everyday experience, we expect “stuff”/“information” to correlate to VOLUME. In black holes, the correlation is to SURFACE AREA. Ergo: For any volume of space, the entirety of the “stuff”/“information” can be encoded with the surface area of the region.

The biggest problem in understanding the universe is the incrediblely limited section of it we can perceive. A small slice of the electromagnetic spectrom as well as it's reflecting off of a of grouping of atoms of a sufficient density and specific composition, Physical interation with groupings of atoms of a sufficient density, very limited ability to determin composition of compounds, and a very limited range of fluctuation in atmospheric pressure. And all two of those deteriorate as we age or are broken to begin with. We've gotten better at building tools to perceive more aspects of the universe, but those are limited by our ability to extrapolate their existance from what we can observe and even then we have to translate the machine assisted observations into concepts we can understand. We aren't just blind men trying to figure out what the elephant looks like. We're blind men with no sense of taste getting a description of the elephant from another blind man that that can only lick the elephant and speaks a different language.

Grom a GR point of view nothing ever really gets into the black hole from our frame of reference. It all just smears out around the event horizon asymptotically approaching infinite wavelength. From Hawking's point of view the entropy of a black hole is propotional to the surface area. If you assume that the smallest quantum of entropy is a square plank length, then ... yeah, the bits within the black hole can be mapped to square planks on it's surface. Weird stuff.

black holes are cosmological copes for the inherent contraditions in reductionist scientistic materialism. so is the quantum realm . so is multiverse . so is dark matter ... much more interesting ways to mentally masturbate out there - ever heard of the cosmological "axis of evil" as explored in the documentary The Principle ? "Some anomalies in the background radiation have been reported which are aligned with the plane of our solar system. These are unexplained by the Copernican principle and suggest that the solar system's alignment is special in relation to the background radiation of the universe.[6] Land and Magueijo in 2005 dubbed this alignment the "axis of evil" owing to the implications for current models of the cosmos,[7] although several later studies have shown systematic errors in the collection of those data and the way they have been processed.[8][9][10] Various studies of the CMB anisotropy data either confirm the Copernican principle,[11] model the alignments in a non-homogeneous universe still consistent with the principle,[12] or attempt to explain them as local phenomena.[13] Some of these alternate explanations were discussed by Copi et al., who claimed that data from the Planck satellite could shed significant light on whether the preferred direction and alignments were spurious.[14][15] Coincidence is a possible explanation. Chief scientist from WMAP, Charles L. Bennett suggested coincidence and human psychology were involved, "I do think there is a bit of a psychological effect, people want to find unusual things."[16] Data from the Planck Telescope published in 2013 has since found stronger evidence for the anisotropy.[17] "For a long time, part of the community was hoping that this would go away, but it hasn't", says Dominik Schwarz of the University of Bielefeld in Germany.[18]" what about : https://www.hoover.org/research/mathematical-challenges-darwins-theory-evolution-david-berlinski-stephen-meyer-and-david
