>And we just perceive it differently at different scales. Like with a stroboscopic light, we might perceive things differently depending on how we are sampling That's actually exactly what's going on with wave/particle duality. Everything's a wave, all the time, but in certain regimes, wave behavior very closely approximates particle behavior. The realization that particle behavior is therefore just a subset of wave behavior is part of the motivation for looking for an omnibus theory that accounts for everything. Unification is not unprecedented, consider e.g. the unification of the weak nuclear force and electromagnetic forces into the electroweak force.

Where’s the incongruence? At a macro scale, anything that happens in time can be considered as a sort of wave that we perceive as an object because of the way we are sampling it Even basic things, like when you measure your own weight, will vary throughout the day/time, but instead of considering them a wave, we usually just “collapse it” into some sort of average of observations Conceptually at least, both models seem to represent the same How are they not compatible? Is it a math issue?

  The main incompatibility is that QM predicts that all fields have a zero point energy associated with each mode. However, GR predicts zero point energy will cause spacetime to curve. However there are infinite modes in QM, so now using this in GR leads to all spacetime instantly collapsing. However we exist so this collapse hasn't happened. The solution is the elusive Quantum Gravity, something that physicists from Einstein, Feynman haven't been able to solve.

    Thank you for the explanation What does it mean for “all spacetime instantly collapsing”? It would be amazing to see a video of a simulation of that
