as far as I know science has not yet fully understood the detailed properties of:
a. energy
b. waves
for example does energy consist of any matter and if not what?
An electron behaves like a particle or a wave in the 2 slits experiment depending on how you watch it.
Electromagnetic waves propagate through a vacuum which raises the question what is doing the waving?
The problem is that the properties of a wave can only be observed and measured indirectly based upon assumptions that may not be entirely correct.
I don't understand why anyone should get upset about answering the original question. The main difficulty with answering the original question is that nobody knows the answers!
