moving at nearly the speed of light.

Couldn't resist being a bit of a stickler but ๐Ÿค“ erm... technically it is moving at the speed of light through a medium, which is slightly less than c, the speed of light in a vacuum. Fun fact, when things move faster than the speed of light through a medium - such as water - it produces Cherenkov radiation, the glowing blue light associated with some nuclear reactors, which is sorta like a sonic boom but with light instead of sound.

That's pretty cool but I did say 'nearly' :-)
