Dirac Delta Function and Quantum Cosmology
The Dirac Delta function is a simple mathematical relationship ("function" is a bit of a misnomer) where the function equals 0 everywhere and infinity at one x-value. This function has often been proposed as a description of what happens when you make a quantum measurement, as proposed by Niels Bohr. The meaning of that is obviously subject to interpretation, but that isn't the point of this article.
Meanwhile, the black hole has the event horizon, then appears to collapse at a singularity (our math just breaks down there, it could lead to another universe or something but our mathematics of Einstein's general relativity cannot currently show us that), or one concentrated "point." This also resembles a Dirac Delta function. Could this similarity in a quantum measurement collapse be used on a cosmic scale like that of a universe, where the "collapse" is a black hole? Maybe we are just much, much smaller than we thought, and to an observer like God who sees this universe as minuscule size-wise, the black hole is just another "collapse" that produces a measurement on a bigger scale, but not a measurement we can see. If we are the size of say a particle, would getting our spin measured give us something we could observe on that level? Obviously, this idea of us just being tiny parts of a much, much larger universe/multiverse is subject to much criticism and debate, as then why do we go from our universe's quantum uncertainty to the deterministic classical physics and then get to the uncertainty of this much, much bigger scale that treats a black hole as a measurement on its own scale? This is all interesting, and hopefully, this area of quantum cosmology can be better explored. Thank you for reading!
