What about the last query? " In that case, since gravity is not a force, no escape velocity is required?"

How is it calculated by GR? Please provide a link.

Since space is curved within the Earth's gravitational field, every body that moves there will follow the curvature of space no matter what speed it has, so what will its trajectory be, how will it be straight, only if the launch is made absolutely vertically towards sea level? Only then can it...

Α "duality" series episode. Debate "wave (spread as Huygens) or particle" (lines as & Descartes diagrams) goes on.

Still sceptical at #11 page contents 19 Is it really a law? & 25 Huygens derivation

I am skeptical like many wiki readers in Talk:Snell's law page contents 19 & 25.

https://www.physicsforums.com/threads/how-is-phase-velocity-related-to-deflection-angle.1010744/ # 8 Snell's law is not derived from Fermat's principle.

It is known as the fluorescent effect, having a different result.

"the resulting "combined" wave may have wave packets that pass an observer at a slower rate." This is an assumption. Is this observed elsewhere, in a TV antenna for example?

I read that drift velocity in superconductors is about 20 meters per second.

You are trying to say that the magnitube of the velocity remains stable. So Maxwell's law needs a revision.

Oscillation of the free electrons (i.g. inside a TV antenna) is known. Oscillation of the orbital electrons inside a material is unknown to me (not aware of QM).

It has an explanation for the slowing down. It has an explanation for the divergence. But it doesn't explain how is Snell's law deduced from the slowing down. Energy decrease means frequency decrease.

Many issues arise. 1. Since wave is spreading according to Huygens law in wavefronts, how it reaches the interface between the materials at an angle? The figure shows an arbitrarily cuted section of wavefronts to create a "light ray". 2. Interface in microscale is not flat but consists of...

This study considers a uniform circular motion in a ring of radius α. Provided that these math apply to a perfect circle circuit, then does not apply to an ellipsoid electric coil or an irregular circuit.
