To all above:

cyreks comment:

Quantum theory portrays light as a 'quanta'. The quanta is a photon. It is
not a wave. It is a 'black body pulse' generated by electron transitions at different energies depending on which orbits the electron transits from.

All physics books explain this. Give Bohr credit for this.

The photon moves through space as a disturbance in the EMF generated by the electrons transition. It does not need spacetime and is not intertwined with space. The EMF is its carrier.
That could be the reason why Einstein was at odds with the quantum theory.
The Quantum Theory has proven itself time and time again.
