# Variations in the Speed of Light — A Response to YouTube’s Veritasium

Hello. I recently watched the Youtube Veritasium video called “Why The Speed Of Light* Can’t Be Measured” (Figure 1). Below are my thoughts on the concept. If you have not watched the video first, please do; my comments will make more sense. Enjoy.

Derek explains in the video that we don’t actually know the one-way speed of light, because all ways of measuring it have been two-way. He brings up a great point and I would like to add to the conversation. The speed of light value is below in Equation 1.

Equation 1: c = 299,792,458 m/s

I hypothesize that the variations in the speed of light is due to the relative velocity that the “clock” or the “sensor” sees. Imagine Earth moving at 100 km/s. The Earth also is moving at a vector that is constantly changing due to the changes in mass that is pulling it (like other stars, planets, galaxies, etc). There is a clock on the Earth. For the experiment that measures the two-way speed of light, the clock is traveling at 100 km/s as well. So, the speed of light is moving in a “diagonal-like” movement as it shoots out of the clock sensor, off the mirror, and back into the sensor.

Notice the elliptical pattern for the example of the Earth in Figure 2. The Earth has an ever-changing velocity and acceleration vector. It is a very small change in those.

Due to these small changes, there must be small changes in the measuring of the speed of light. Thus, there will never be an accurate measurement of the speed of light. Equation 2 is the famed Einstein equation that explains the relation between energy, mass, and the speed of light.

Equation 2: E = mc²

I postulate that the naturally occurring speed of light is a never-ending non-repeating number, like pi. There may be an “average” velocity of light though. This may be the value that is being honed into as Equation 1.

I also postulate that the speed of light is dependent on the gravity pulling it. It depends on the amount of mass in front and behind the photon as it travels. If there are more galaxies in front of the photon that behind it, it will be pulled a certain amount of acceleration (or gravity) towards it.

What are your thoughts? Do you agree or disagree? I would love to hear your thoughts. Thank you for listening.
