What If Something Travels Faster Than The Speed Of Light?

The video explains the concept of a Sonic boom, which occurs when an object travels faster than the speed of sound, and introduces Chettenkov radiation, discovered by Pavel Chettenkov. Chettenkov radiation occurs when particles travel faster than light in a medium other than a vacuum, similar to a Sonic boom but with light. The video also covers the Doppler effect and how light speed varies in different mediums, leading to Chettenkov radiation in nuclear reactors.
