Still wondering about it, too.

It may be the laser being refracted by the air, just like commercial green lasers are refracted by fog. I actually think is the only explanation.(And neutrinos, because seriously, neutrinos rock).

Also, I can see some interesting uses to this camera, beyond light studying...

It is. Seeing is interacting with photons, so you can't 'see' a photon that didn't just hit your camera. The process is similar to how I heard we can see speed of light in space, as light from exploding star propagates through a nebula and reflects back to us. I can't find a reference for that though, I heard it as a story from a physics professor.

And magnets.
