Origin of our universe 4D black hole

Click For Summary
Recent discussions at the Perimeter Institute suggest that our three-dimensional universe may exist as the event horizon of a four-dimensional black hole. This model raises questions about whether three-dimensional black holes could contain two-dimensional universes within their event horizons. Skepticism exists regarding the validity of this theory, with some participants expressing doubts about the accuracy of general relativity at black hole scales and the existence of singularities. The conversation also touches on the nature of proof in physics, emphasizing that while empirical observations can support theories, they do not constitute definitive proof. Ultimately, the thread has veered off-topic, prompting a suggestion to close the discussion.

But perhaps our own universe is a computer simulation, which there is no way to prove or disprove at the moment, so if it is a computer simulation, in this case there would have to be an underlying mathematical model that IS reality because our universe is governed by it?

Give it a rest. You're just trying to win an argument that you have already lost.

Moderators, please close this thread.

I recommend Karl Popper's The Logic of Scientific Discovery for his insights into verification-ism as proof and developed a much better solution to the Problem of Demarcation in falsifiability. On point, fifty years after 'Logic' he wrote an anniversary postscript that grew into three volumes, one of which is Quantum Theory and the Schism in Physics: From the Postscript to the Logic of Scientific Discovery (1992 Routledge).

On proof, in general, a number of contemporaries, influential at least to me, caution against naive use of inductive inference for not reliably revealing the Black Swan hiding, camouflaged in the background complexity of reality. An assertion of non-existence cannot be sustained without examination of the entire universe of discussion. In physics and cosmology that is clearly impossible.

Our young member must needs read on the Boltzmann Brain and the Boltzmann Babies paradox, aspects of cosmological natural selection, and beware of infinite regressions.

Later; and of ad-hockery! Make your argument and let it stand or fall on its original structure, rather than patching and shoring a shaky structure into a cracker-box.

The discussion in this thread is no longer on the original topic. The thread will therefore remain closed.
