  1. Yes, e.g. radar bouncing of a moving airplane. If you insist the 4 acceleration is perpendicular to the plane’s 4 velocity, you will recover the 2 way Doppler shift.

  2. Achtually 🤓that’s a common misconception. The relations between the fields are not causal. See: Jefimenko’s eqs.

  3. But c does depend on how hard the couple. Not how fast.

  4. See Poynting vector in linear media. The energy density goes up when the light slows down, but the power density remains constant.

  5. It’s passé. It makes the famous eq work in all reference frames, but scalar rest mass is better.

  6. No

  7. Quantum mechanics is nonrelativistic

  8. Your post contradicts relativity. You can’t move relativity to space.

  9. They are only moving relative to each other. There is no moving through space.

  10. It’s electric permittivity and magnetic permeability

  11. You can certainly cut each side faster than light, but the scissors ✂️ only differ engineering concerns. Not physics limitations

  12. Pls, no one way speed of light comments. It’s not relevant.
