  • The paranormal community at large has been treating UFOs and aliens as transdimensional entities indistinguishable from historical and biblical demons for a long time now, including Djinn, fae, elves, earth spirits, and ghosts.

    'Demon’s the way they use it are ones who reveal themselves, as opposed to those who hide in the shadows. Demon - strate, demonstrate themselves.

    I doubt it, calibrating a focal point to a stationary, relatively nearby target, say a hundred metres or so, is fairly simple, but to apply that to a satellite, a moving target (with a changing velocity if we are talking about a satellite in an eccentric or molnya orbit) either in high or low earth orbit, that’s a distance of between 200-20,000kms.

    Even a satellite in perfectly circular orbit is constantly changing its distance relative to a point on the ground, meaning you have to constantly adjust the focal point of the mirrors. At 250km, your field of mirrors (say, a 100m circle of them) would describe about 0.023 degrees of curvature, almost completely flat.

    And that’s before accounting for atmospheric attenuation and scattering of the light.

    On a clear night with many gw of laser energy, maybe you could peel the skin off a low orbit satellite, but even that would be impractical.
