The speed of light 😳😱

That is no where close to the speed of light.

Will it disappear when accelerated to the speed of light

That's the speed of burning gun powder in shock tubing.

That is not the speed of light…

This has nothing to do with speed of light!

This should be speed of electricity rather than speed of light 🫢

Not even close, this video demonstrates how it would look to travel across the globe at the speed of light.

Wrong.... Not even close. I saw the original demonstration years ago and its an explosives fogged into the tube to give an example of the speed in MS of said explosive. I looked but can't find it anymore. @CommunityNotes

299,792,458 m/s or 299,792.5 km/s or 186,282.4 miles/s or 670,616,629.4 miles/hr

Is this optical fibre cable. Because if it is not then its not the speed of light it be the speed of electricity, which is 70% the speed of light.
