Re: What-If 0032: Hubble

This is actually a GOOMHR moment for me, as I am just completing a conference poster about radar imaging of space debris from server sky . The problems are similar; I wonder what one could do with space telescope optics and a femtosecond strobed laser , with some kind of coherent mix/detection in t...

Re: What-If 0032: Hubble

FWIW, it was pretty much an open secret (at the time Hubble was built) that classification restrictions were what forced NASA to award the Hubble telescope contract to someone other than, say, Kodak, which at the time was cranking out nice big telescopes for spysats. The primary was made by (then) ...

Re: What-If 0001: Relativistic Baseball

As pointed out by others, I doubt that fusion would be at all interesting here. 0.9c is way too hot, and there is no confinement or compression. Energy would be absorbed by disassociating the light nuclei C, N, & O into nucleons. You would thus have some amount of free neutrons running around, b...
