Slowing The Speed of Light Down To 2 m/s—What Special Relativity Feels Like
In this video I show you what it would look like to slow the speed of light down to around walking speed. So with just walking around town you would experience relativistic effects. I talk about time dilation and length contraction and what it would look like to have it happen to you. Get the… Continue reading Slowing The Speed of Light Down To 2 m/s—What Special Relativity Feels Like
