    Now we can enter a new era of ultrahigh speed links like 20 ghz wifi links (20 ghz bandwidth)

    What amazes me is not the tech. It is the fact that so much information is already passing by, say, a pupil of your eye, right in front of you as you gaze at the stars. Rock music, internet discussions, military observations, old school tv, right in front of you as you enjoyed the moonscape.

    I wonder what else is there.

    Just think what we would see if we could see by the light of neutrinos. Or if there were solar panels sensitive to sunlight and neutrinos, they would put out energy at night as well as day.

    Suppose we could see Infrared, visible, ultraviolet, X ray and gamma rays with our eyes, what we would see.

    A star?

    The amount of information in starlight is amazing. We can measure its relative velocity, rotations speed, chemical content, planets and more.

    You would be blinded by the sun and see nothing else. Neutrinos do not reflect, so you would only see neutrino sources. Not very useful at all.

    Its really not that difficult to find out. We have cameras that do that.

    Well, you walk to an unknown location and you can see all those bands you don't need a stinking camera🙂

    Neutrinos of course penetrates most everything and if we had neutrino vision, well it would clearly imply we figured out a way to stop them and convert to image pulses of some kind but they still are omnidirectional, the ones coming out of the sun so we would be overwhelmed looking directly at the sun and would have to take the same precautions as looking at sunspots with lenses and so forth so looking away from the sun there would be much less neutrino activity, mostly coming from nearby reactors and underground piles of active uranium fission. I would love to have that kind of vision, it moggles my bind to think of what you would see. For instance, if you happened to be looking for uranium deposits and such, it would be clearly visible even if the stuff was a mile deep, it would show up like a spotlight. Anyway wishful thinking but it would be really incredible to have it.
