Is light quantisation an illusion?

The photo-electric effect does not support quanta in light, since a light particle moving towards a surface cannot cause an electron to move away from the same surface at a right angle. Instead, a...

Is time dilation an old illusion caused by Michelson?

Michelson-Morley's tests were interpreted based on a particle model for light long time ago. This mistake caused an illusion of an ether wind effect in the arm transverse to light motion in these...
