Certain theorists such as Smolin have take this seriously. Although it is an officisl "problem definition statement" in many graduates school programs, I think it would be useful to clarify the collective concensus on this.
Einstein went even further to claim QM is not a completely or sufficiently by physics stsndards defined physical system, which is maybe another issue in itself..
Dear friend Philippos Afxentiou
Hey there! I am here, diving into the depths of the scientific realm. Now, let's talk about Einstein and his skepticism toward Quantum Mechanics (QM).
Einstein, despite being one of the founding fathers of quantum theory, was never fully comfortable with its implications, famously stating that "God does not play dice with the universe." His main concern was with the probabilistic nature of quantum mechanics, as encapsulated in the famous Schrödinger's cat thought experiment.
Now, the scientific community has had quite a journey with this. While quantum mechanics has proved incredibly successful in describing the behavior of particles on a small scale, the philosophical questions it raises, including its apparent indeterminism, have kept debates alive.
Some physicists share Einstein's sentiment that there might be a deeper theory yet to be uncovered, a theory that could reconcile quantum mechanics with our classical understanding of reality. This pursuit has led to the exploration of alternative theories and interpretations of quantum mechanics, such as hidden variable theories.
However, it's crucial to note that the majority of the scientific community accepts and uses quantum mechanics as a highly successful and accurate framework for understanding the behavior of particles at the quantum level. Quantum mechanics has been tested and verified to an extraordinary degree of precision in numerous experiments.
So, while there may be ongoing debates and alternative viewpoints, the general consensus within the scientific community is that, as of now, quantum mechanics provides an excellent and accurate description of the quantum world. But hey, science is a journey, and who knows what discoveries lie ahead?
Usually we think of quantum mechanics describing the subatomic world, of electrons and atoms, but Stephen Hawking was thinking of the entire universe as a quantum system.
Combining Einstein’s general theory of relativity, which dictates the space-time curvature of a black hole, with quantum field theory, which describes the strange, ephemeral nature of seemingly empty space, Hawking showed that black holes actually radiate.
Hawking’s view is interwoven with his revelation that black holes are not truly black.
Hawking claimed that if you wind the universe back to the beginning, time loses its distinct nature and effectively becomes space. With this no boundary hypothesis, the universe did not have an origin, not at least one we would ever really understand.
The goal of modern science has been to unravel the fundamental operations of the universe and use these to predict how physical systems evolve. To do this, we need more than the laws of physics, but we need to know the starting point, the boundary conditions, if any.
Well, QM is quite complete mathematically (boils down to solving a certain differential equation), and in physics within the scattering theory (solve the evolution equation up to large times, then convert the solution to probability). Beyond the scattering theory it does not tell exactly at which time the probabilistic collapse occurs, in which reference frame, can it affect only a part of the degrees of freedom, etc. But experimentally, such an information is difficult to access, too. So, QM is “virtually complete” in the sense that it can provide predictions for most of the feasible experiments.
