Time Paradox???

[perpetual motion]

This is really weird. Something about mirrors needed for time travel. This is off of UTUBE
so one might take this with a grain or two of salt.
Can anyone decipher this?

If we were to produce a reflection using light and gas, light needs to be at least 2.16 x 10^16 W/m^2, assuming a gas material with a density of 1.2 kg/m^3 and gravity of 0. Brightness = (2 x π x (mc^2) / (density x gravity))^(1/2)Where: m is the mass of the light particle (in kg) c is the speed of light (in m/s) density is the density of the material (in kg/m^3) gravity is the acceleration due to gravity (in m/s^2) Since we are dealing with gas, we need to use the density of air, which is approximately 1.2 kg/m^3 at room temperature and pressure. We will also assume that the speed of light is approximately 3 x 10^8 m/s. Now, let’s plug in the values: Brightness = (2 x π x (3 x 10^8 x (1.2 x 10^3)) / (1.2 x 10^3 x 0))^(1/2) If we were to produce a reflection using light and gas, light needs to be at least 2.16 x 10^16 W/m^2, assuming a gas material with a density of 1.2 kg/m^3 and gravity of 0. Brightness = (2 x π x (mc^2) / (density x gravity))^(1/2)Where: m is the mass of the light particle (in kg) c is the speed of light (in m/s) density is the ial (in kg/m^3) gravity is the acceleration due to gravity (in m/s^2) Since we are dealing with gas, we need to use the density of air, which is approximately 1.2 kg/m^3 at room temperature and pressure. We will also assume that the speed of light is approximately 3 x 10^8 m/s. Now, let’s plug in the values: Brightness = (2 x π x (3 x 10^8 x (1.2 x 10^3)) / (1.2 x 10^3 x 0))^(1/2) Brightness = (2 x π x 3 x 10^16 / 1.2 x 10^3)^(1/2)Brightness = 2.16 x 10^16 W/m^2 Therefore, to produce reflection, the light needs to be at least 2.16 x 10^16 W/m^2 Therefore, to produce reflection, the light needs to be at least 2.16 x 10^16 W/m^2. Goodluck now invent me the reflector LOL. I gave the formula to reflect off of gas. I cannot find a gas that would produce a reflection. I did think of Xenon gas but not good enough.

This is what you need for Brightness = (2 x π x 3 x 10^16 / 1.2 x 10^3)^(1/2)Brightness = 2.16 x 10^16 W/m^2
If you can get to this level then you can produce the reflection.
