Speed of light drops to zero at 'exceptional points'

[Kent Sharkey]

Phys.org[^]:

Light, which travels at a speed of 300,000 km/sec in a vacuum, can be slowed down and even stopped completely by methods that involve trapping the light inside crystals or ultracold clouds of atoms.

So I can move at the speed of light? Exceptional!

So that's what happens when light goes in one ear and doesn't come out the other.

Don't let your mind wander too far. It's too small to be let out alone.

Mine is non-zero at 'exceptional points'.
