Wow, we are all inside a black hole! A theory that has been running for some time (together with what we are inside an hologram, which we are a simulation, which we are in a multiverse, etc.). But let’s see the last. The latest observations of the James Webb Telescope found that galaxies have a preferential sense of rotation (at least the 263 galaxies observed, on hundreds of billions of galaxies).
However, if we were in a black hole, wouldn’t we be attracted to the center, while the universe is an accelerated expansion? No, because we would already be inside the black hole, so the horizon of the visible universe would actually be the horizon of the events of a black hole seen from the inside. And the black holes of which our universe is full? Access doors towards other “children’s universes” (that they are children very much, as if we could do something to us, how to try to get into it to find childhood).
The idea is not new: already formulated by the theoretical physique Raj Kumar Pathria and the mathematician IJ Gold, up to the Polish theoretical physique Nikodem Poplawski. I don’t know if you have noticed one thing: theoretical physicists. Which is not an insult, Albert Einstein was also a theoretical physique. But from the formulation of general relativity to the evidence of general relativity (when Einstein’s theory was accepted by the whole scientific community) only four years have passed (from 1915 to 1919), and for a century he has been holding all the forecasts. It is the model that currently works most, and those who will reconcile it with quantum mechanics (which will probably not be a single scientist but many, because there was only one Einstein) will win the Nobel.
What makes me laugh is the enthusiasm for every minimum clue different from the current model, as if something changed for us, or as if every hypothesis led to something consoling. So: multiverse, cyclical universes, holographic universes, simulated universes, universes within black holes, universes without beginning, quantum severity with loops, emerging severity, 26 -dimensional strings theories, 10 -dimensional superstries, 11 size, and whoever has more put them, and is fine, but what is it that makes you so euphoric? My friend Gigi Ballarani, an expert from Ai and Fan of Elon Musk, is convinced that he lives in a simulation. What a difference I do not know.
In any case, we must remember what Richard Feynman said, not an ordinary theoretical physique: “Science is imagination in a strength shirt of experiments”. Without strength shirt, science becomes science fiction and metaphysical physics.
