−time and space both emerge from discrete causal sets and so infinitely divisible time and space are illusions of our discrete reality.
• Second rabbit hole is the notion of relativity without any quantum phase, Schrödinger’s phase decay paradox
−quantum phase decay plays no role in gravity relativity
−quantum gravity emerges from discrete causal sets with quantum phase decay limiting entanglement and correlation
Zeno's paradox is quite well known and has many different versions that all amount to the impossibility of infinitely dividing space and time.
There are scientists who spend their entire career in either or both of these rabbit holes and even make money from their book sales.
