Interesting video, Paul.

A couple of things I'm not absolutely clear about.

When an atom absorbs a photon it acquires more energy. The impact slows it down, so it loses kinetic energy. Is the kinetic energy lost greater than the energy of the acquired photon, or is something else going on?

Where does the energy go? Does the laser beam become hotter? Where does the heat go?

No doubt all these questions will be answered, and possibly someone may comment on the fact that the non-layman said the atoms are in a quantum state. Oops!

There never was nothing.
