Good thinking...
A worthwhile research and development effort...
OTOH, in addition, maybe that group that claimed to identify the the “shape” of a photon could design the engine-beam photons into arrowheads so that beam spreading would be resolved...
Why does beam spreading happen in the first place? Even laser light does it, just on a smaller scale, but why?
According to physics, it’s the ‘wave-like’ property of light that causes it.
But light has two properties, the other being the ‘particle-like’ property.
The photons are reacting with something...................
