    Interesting indeed, although it always seems that the signal lasts for a second and then disappears never to be heard again! Same thing happened with the 'Wow' signal. What does he mean by laser pulses anyway? I dont get how you could communicate using laser pulses to some rocket in outer space?

    it's been experimented before, I think the military is exploring this technology because of the insane bandwidth you can cram on a pulse of light

    Yes, and we use pulsed LASER in every fiber optic line. It is the basis of modern communications technology.

    You would modulate it, like any other signal.

    How often do optical anomalies that look like the detected pulse occur? Considering how prevalent laser equipment is, surely there's very good information on this?
