Reply to comment by CrustalTrudger in What will be the environmental impact of de-orbiting 42,000 Starlink satellites every five years? (Explanation in post) by OvidPerl

Isn't it funny that "stop that till we know exactly how much harm it does" is never really pursued as a policy option

More research is needed! the scientists cry as the entrepreneurs do whatever they like

And of course when what they are doing is proven deadly & regulated out of feasibility, they will have new unproven methods to turn to

Reply to Why can’t you “un-blur” a blurred image? by so-gold

it depends on how it is blurred. if they used the same procedure for every pixel, it can be reversed, it is even possible to write a program that finds out, how it is blurred.

but if you tell the program to use a random seed (0-5 for example, every time it blurrs one pixel, this new pixel has got a different base.

Reply to comment by gsohyeah in What does it mean for light to be an excitation in the electromagnetic field? by Ethan-Wakefield

It is irresponsible how incorrect this explanation of physics is. Rotating a magnet does not simply create EM waves. The changing magnetic field from the rotating magnet is not the same oscillating magnetic field induced by a photon.

Photons are not simply ripples that propagate outwards from some disturbance of a field.
