The simulation hypothesis tested by quantum computing and energy limits, is a realistic simulation physically impossible or just an optimization problem?

Scientists have used a 5564-Qubit quantum computer to simulate a potential cosmic and cataclysmic event: the disintegration of the vacuum. This experiment opens up...

Is realistic simulation physically impossible or just an optimisation problem?The researchers of the Department of Physics and Astronomy of the University of Bologna, Via Gobetti, Italy, have assessed the degree of physical realism of the "simulation hypothesis" for this universe, based on the physical constraints arising from the link between information and energy, and astrophysics constraints...
