LOL and this from someone who thinks that for a telescope to take a time lapse photograph it needs to compensate for sidereal motion : ) Have you done the simple experiment I asked you to? It neatly demonstrates the time difference in apparent position.
electromagnetic waves are entirely different, carrying (or composed of) both magnetic and electric fields and are not known to require any medium!
Correct, but there is a field. What is the field made of? I claim that the field is made of nothing, hence waves of nothing.
Electromagnetic waves are waves of electricity and magnetism. They can be detected by either magnetic sensors or electric potential sensors. They aren't waves of nothing. (I think it's some sort of hybrid crippled idea which assumes that Electromagnetic waves must also be carried by motions in a massy media just like sound waves.)
So please explain your hybrid crippled idea : ) This should be fun.
I think my crackpot science detector is lighting up like a Christmas tree on 220 volts! Maybe even 440!
Good! Skepticism is the beginning of wisdom : ) You might learn something, even if I have to drag you screaming and crying : )
I need you to do a little research on the electromagnetic spectrum, because I know that you won't believe anything that I tell you. In the upper frequency ranges 10 to the 18th oscillations per second and above, does the chart describe waves or particles?
In a little while (or maybe longer in your case) you are going to be thanking me for opening your eyes. But I can't take the credit, I have just decided to walk you through "The Feynman Lectures on Physics." Some people seem to require public humiliation to learn.
