    I think it should be pointed out that the EM wave in vacuum isn't actually moving up and down in space. I've tutored many students, and this is what they commonly think. It is the strength of the electric and magnetic field that oscillates, so, if looking along a single propagation axis, the EM-wave is literally on a straight line that doesn't move up or down. The field strengths along this straight line merely oscillate between a maximum and minimum value.
    I just wanted to point this out because from my experience of tutoring, many students thought the EM-wave looked like that in space, like it was a string or something.

A lot of professors and doctors answered me but in fact they didn't know :P Only one person wrote an answer that makes sense i.e. that momentum is a very general notion that stems from the Noethers theorem and conservations principles.

    This is great at how the math works. But a cross product is used to make them perpendicular, so "why" they are perpendicular is completely skipped. A causal mechanism is where you get to understand it. Describing what you see it do with math is not an understanding. Then I need to add that laws and rules are mnemonic devices, not causes. The variables in gravity math are probably incidental, not causal, so anything with a constant in it is suspect. Math is a rote memory procedural path into these things that followers cannot let go of, because it is all they have. If you believe in angular momentum, look at my latest gyro explanation that is based in acceleration, and please let me know that you can see "causality" beyond the description.

      Importantly and fundamentally, what is gravity is, ON BALANCE, an INTERACTION that cannot be shielded or blocked. What is E=MC2 IS dimensionally consistent.
      Consider what is THE EYE, AND notice what is the black “space” that is associated with what is THE EYE ON BALANCE !!! Now, think about TIME. Think about SPACE !!!
      The stars AND PLANETS are POINTS in the night sky. Consider what is the Sun. Consider what is THE EYE !!! Now, think about TIME. Excellent !!! Consider what is THE EYE that actually IS IN what is outer “space” ON BALANCE. Indeed, think about TIME !!! NOW, consider what is the man (AND THE EYE ON BALANCE) who actually IS standing on WHAT IS THE EARTH/ground !!!
      TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE, AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE) !!!!

Accordingly, ON BALANCE, what is E=MC2 is taken directly from F=ma; AS the rotation of WHAT IS THE MOON matches the revolution; as the stars AND PLANETS are POINTS in the night sky. Consider TIME AND time dilation ON BALANCE.

      He explains it very well, what do you mean? He literally showed you that Maxwells equations were volume chargedensity and currentdensity is equal to zero in free space, which simplifies Maxwells equations. Because the curl of E and B are coupled diff equations, you have to use curl to decouple them. We then see that we get Laplaces equation which satisfies the the general formulation of the wave equation. Letting f first equal to E in the wave equation you can solve for the speed v. Lastly, we see that v equals the speed of light, which means that light consist of a electric and magnetic component as it propogates through free space with the speed c.

    Universaldenker, you got to get your fact correct to be a universal thinker. I know you are not expecting critics of Faraday / Maxwell, but I look at real science, not the name behind it. in real science = Persian, There is no magnetic / electric field in light. Light is a stream of photon. Photon has physical structure that explains its travel from A to B and interaction. The electric field needs a surface to display its property. Moving Magnetic dose move electron in conductor, but current dose not create magnetic field. Man dose not know structure of matter to understand magnetic field is by product of matter function. This is normally mitigated by electron. When electron is forced to move by a potential, the magnetic flux can escape and be detected outside conductor. This has made Maxwell to reach wrong conclusion that e/m wave in space made of e and m.
