Capturing the Speed of light

Lame ad just as flat earthers. Light is way faster.

This experiment does not show even one hundredth of a percent of the speed of light

No, that's not the speed of light. Detonation cord is probably being used in this experiment to measure the speed of some explosive material. Our eyes can't even catch light travelling such a short distance because it can trip the entire globe within about 0.13sec.

This is not the speed of light. It is the speed of light in a transparent material. I suppose it is glass fiber where the speed is roughly 200.000 km/s. The usual definition of c0 of ca. 300.000 km/s is in a vacuum.

It’s not the speed of light. It looks like some sort of combustion.

This is very cool. But it’s not the speed of light

Physics is wonderful. Great perspective on light.

This is incredible

Erratum: Capturing a fraction of speed of light

@Yeenccs Asking at a risk of sounding dumb. Can photons move like that?
