A device which will let us see all!

    first thing, do you think such a device can be technologically feasible?
    do you think we need it?

    i think if we can build such a device why not?! i think the advantages of it are more than the disadvantages.

    See all what?

    All the spectrum of the light.

    You can't build a single device that sees the entire spectrum, but you can build a bunch of separate devices that see parts of it and link them together. Same effect.

    At some point you would have to sacrifice resolution for bandwidth for the final "viewing"; or you would only be able to view sections of the spectrum at any time.

    As an upper limit, I suggest the frequency √ = E/h; where E is the total energy of the universe.

    We will need an infinitely long antenna for the low end.
    :wink:

    square root of what equals E/h?

    I just thought the radic looks more like the nu that I know and love.
    I meant frequency = E/h
