You cannot construct a logical theory of physics in which some aspects of physics are quantum and others aren't. That's what I mean by Quantum Mechanics infecting the rest of physics.
This is why after the discovery of Quantum Mechanics, there was a drive to formulate quantum versions of all fundamental theories.
- goatlover 4y agoAnd what if we fail to formulate quantum versions of all fundamental theories? Again, nature doesn't have to play along.
- DiogenesKynikos 4y agoNature does have to play along, because whatever the correct theory of physics, it has to be logically coherent. Either everything is quantum, or nothing is. Given that we are pretty darn sure that most of physics is quantum, we're pretty sure the answer is that everything is quantum, not that nothing is quantum. There are different ways of formulating quantum theories of gravity (in fact, you can derive the Einstein equations fairly straightforwardly by trying to formulate a quantum theory of a massless spin-2 boson). We don't know which of those theories is correct yet, but it's not as if there's no way to quantize gravity.
- goatlover 4y agoWhat makes you so sure reality is fundamentally quantum and not something else we've yet to discover/formulate that underpins QM and everything else?
- DiogenesKynikos 4y agoYou should read about Bell's theorem to understand what the alternatives are. Experimental data now makes the alternatives vanishingly likely.
