Hi. I think there has been research about the idea that time may not exist on the very fundamental level of reality. Does anyone know if space exists at that same level? I have read somewhere that at the Planck level, which is the smallest level physicists have gone to, time and distance drop out of the mathematical equations.

Read where? We can't explain what you've read if we don't know what it is.

Its possible - but its highly speculative.

Since we know space and time don't exist independently and we really have space-time if time is emergent its a pretty safe bet space is as well.

Thanks

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
