Here are a few commonly heard sentences that will make my question clear:
Statements #1 “The Michelson Morley experiment once and for all did away with the ether or the idea that light needs a medium in which to travel” “Light can travel through empty space”
Statements #2 “Light travels though the electromagnetic field” “The photon field is only one of the fields for each particle in the standard model.” “There must be dark matter in the universe for our current model of gravity to make sense.” “Space is not empty. A quantum foam fills it”
You can see the confusion that arises from the conflicting statements which are commonly heard in physics.
The fact that light travels via an electromagnetic field is in clear contradiction to the statement that light travels through empty space. I suppose we could try to join empty space and the EM field into one thing by saying light is the field. Frankly, that sounds like doublespeak.
What am I missing? Light is a disturbance in the EM field. There is no empty space. Light travels through a field.
Why do some physicists say light can travel through empty space?
