light does not travel along all paths at an even speed

Bringing up this video again. Anyone can measure on the screen the difference between radius of the left side top and bottom and see that light is travelling at different speeds. So if it's not from aether drag what is causing the difference?

Some paths are longer than others?

like 2 paths in the woods?

Sure. A curved path is longer than a straight one.

Virtual femto-photography is a technique that uses ultrafast laser pulses to capture images of light in motion. It allows for the visualization of the propagation of light through a medium or scene in slow motion, even if the process occurs too quickly for the human eye to perceive. By capturing a series of femtosecond-duration snapshots, virtual femto-photography can create slow-motion videos of light moving through a scene, providing valuable insights into phenomena such as light scattering, reflection, refraction, and absorption. This technique has applications in various fields, including physics, materials science, biology, and engineering, where the study of light-matter interactions is crucial.

Light does not travel along all paths at an even speed primarily due to the phenomenon of refraction and different mediums through which it travels.

1. Refraction: When light passes from one medium to another (like air to water), its speed changes, causing it to bend. This change in speed and direction is due to the change in the optical properties of the medium.

2. Optical Density: Light travels faster in less dense mediums like air compared to denser mediums like glass or water. This difference in speed causes light to travel at varying speeds along different paths.

3. Dispersion: Different frequencies of light can travel at different speeds, leading to phenomena like chromatic aberration in lenses.

4. Scattering: When light interacts with particles or molecules in a medium, it can scatter, causing variations in its speed along different paths.

5. Gravitational Lensing: In the presence of massive objects like stars or black holes, the gravitational field can bend light, affecting its speed and path.

In conclusion, due to these factors, light does not travel along all paths at an even speed.

String theory, which is generally not see as right, found that it needed light to be in many dimensions, like twenty, then they got it down to about eleven.

We can't see how light moves, how it is, as a very, very small level, and perhaps it's doing some weird stuff we can't grasp yet.
