8: The Holographic Principle.
At the event horizon, at a black hole: What happens? Susskind won the argument against Hawking: Events are displayed as "holograms" at the edge of the universe!
But! Not only black hole events are displayed! All events are!
Who's watching?
Admittedly my understanding of this topic is somewhat shallow, correct me if I'm wrong. From what I've seen it's mainly the Information paradox and the Holographic principle that lead to this disturbing trend in science nowadays that makes a few scientists so enthusiastic about proving that we live in a simulation. Like this possibility was the best thing since sliced bread for them; I have no idea why. Sure, the simulation can never be ruled out, and the infinite multiverse hypothesis also automatically has to contain simulated universes, even though I'd argue that their ratio would be very low, which is my primary reason for rejecting the simulation hypothesis (I expanded on this and my other objections in the Electrical reality topic, and I largely agree with Noax's objections too. The interpretations of QM are in particular way off.)
But back to the Information paradox. If I understand correctly, it all probably goes back to one certain question about QM: are quantum fluctuations
genuinely random or
apparently random? Hawking, Susskind and almost everyone else seem to have taken the genuinely random interpretation for granted. They hardly could have done otherwise; this is what we can tell from our experiments, an apparently random local behaviour of a universal nonlocal determinism for example may forever be unprovable, even if it might be a possibility.
So they had to take the genuine randomness route with genuinely random quantum fluctuations. As black holes evaporate, physical information is lost, which pretty much breaks physics. Maybe it's true and this is how the world actually works, which would really be painful. So they had to come up with all kinds of ideas to fix it, and so they came up with an even worse idea: that information is encoded on the event horizons of black holes. That's the ultimate mindfuck, because information is just an abstraction of physical systems, not an additional physical component. Science has therefore entered magical thinking territory.
Then there's the Holographic principle: an n dimensional something can be represented on an n-1 dimensional surface. That's all nice and well, but that doesn't necessarily mean that that's the case for our universe.
So the way I see it: we have a forced but
maybe incorrect assumption (genuine QM randomness) resolved by a cognitive error (encoded information), married to a mathematical tool and physical possibility taken literally and for granted (holographic principle applied to the universe). And that's the main argument for the simulation hypothesis. That's too forced imo. It's reasons like this why I started the "Information does not exist as such" topic on this forum. Some scientists and philosophers take it very seriously nowadays that information exists
in addition to matter/energy, which is nonsense, and as long as they have this belief it's no wonder that many people think they are holograms or the world is a simulation and so on. People like Susskind and Dennett may have lead humanity a little astray, for a while.
Overall I see the topic as heavily metaphysics of course, but wouldn't call the simulators supernatural; they use no Magic. I think the multiverse hypothesis is the simplest and most likely "unprovable extension" to the world we see, it easily beats the simulation hypothesis. With the simulators we also also may fall into the "yeah but where did God came from" type of infinite regression too: the existence of the simulators should possibly be explained as well, which again may need further simulators or other universes and so on; and we eventually may have a multiverse again.
