Origin of our universe 4D black hole

SUMMARY

The Perimeter Institute's recent paper posits that our three-dimensional universe may exist as the event horizon of a four-dimensional black hole. This model suggests that black holes could harbor two-dimensional universes within their event horizons. While some participants express skepticism about the validity of this theory, citing a lack of extraordinary evidence, others emphasize the importance of mathematical models in understanding physical phenomena. The discussion highlights the ongoing debate about the nature of reality and the limitations of current scientific theories, particularly general relativity.

PREREQUISITES
  • Understanding of general relativity and its implications for black holes
  • Familiarity with the concept of event horizons in black hole physics
  • Knowledge of mathematical modeling in physics
  • Awareness of the philosophical implications of scientific theories
NEXT STEPS
  • Research the implications of the Schwarzschild metric in black hole physics
  • Explore the concept of holographic universes and their mathematical foundations
  • Study the Boltzmann Brain and Boltzmann Babies paradox in cosmology
  • Investigate Karl Popper's philosophy of science, particularly falsifiability
USEFUL FOR

Physicists, cosmologists, philosophers of science, and anyone interested in the theoretical underpinnings of black holes and the nature of the universe.

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.

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.
