The origin of spacetime is one of the most intriguing questions of the fundamentals of physics. This is one of the many questions that has essentially troubled scientists for centuries. Modern-day theorists have come up with several frameworks that have tried to approximate the main conditions that led to the emergence of spacetime. Some of these theories are emergent gravity, causal set theory, information theory, and multiple models within the enterprise of quantum gravity. 

Physicists have been pondering for long that space and time are essentially derived properties from something more concrete, however, it is still not very clear as to what that more fundamental thing might be. There are several pieces of evidence in the scientific literature that apparently hint towards the non-fundamentality of spacetime.  Essentially with the gauge-gravity duality proposal, theories of spacetime emergence...
