What does QM hint about time-space?

[San K]

Does QM hint at time-space being an emergent, rather than a fundamental, property/constituent of nature?

In what ways?

Electromagnetic (EM) fields are assumed to pervade all of time-space.

Which is more fundamental?

Standard QM and QFT use space-time as a background, I don't think they give any hint at the structure or properties of space-time. Maybe symmetries are the only thing touching on the subject, but other than that...it's really difficult to define a time operator (as an observable), but I could be wrong.

However , from what I understand, with LQG, it's a whole different story.

Some investigative takes on that are hinted in various threads here:

No - it hints that nature may be fundamentally modeled by generalised probability models.

QM is fundamental - Maxwell's equations follow from QED - not the other way around.
