Length Contraction Explained | Brian Cox

Very informative 👍

The carbon compression of the diamond slows light… the compression of a carbon plane can suppress the speed of light by 25% before crossing a transformation zone…into a lower entropy state

More peripheral…

The mass of the proton must increase. How big does it get?

27km to 4m is not that significant difference though

Ok, and what's that matter?

Does the distance actually physically shrink at the speed of light or does the distance seem shorter because it's moving at the speed of light??

The key word is perspective
