Pariah Posted April 14, 2018 Report Share Posted April 14, 2018 Darkness is the absence of light, just as, thermodynamically speaking, cold is the absence of heat. Quote Link to comment Share on other sites More sharing options...
Bazza Posted April 15, 2018 Author Report Share Posted April 15, 2018 Woah...so St Augustine was right about sin. He stated it was a privation* of The Good. *absence being a synonym. So, very similar thinking involved. Quote Link to comment Share on other sites More sharing options...

Cancer Posted April 17, 2018 Report Share Posted April 17, 2018 8 hours ago, L. Marcus said: The unbearable lightness of a close-range supernova, so close that the neutrinos alone can shred you. Just for grins, back in grad school, we estimated the lethal radius of the neutrinos from a core-collapse supernova. (The neutrinos emerge an hour or two before the shock wave from the core hits the surface and you can see the explosion, so there is a brief time when yes, the weak force could kill you outright if you were in the wrong place.) That estimate was about 5 AUs. Though I realized there is a safe spot from that if you know it's coming (and it would be exceedingly hard to tell it was coming, but never mind that). Jovian planets are partly supported by electron degeneracy, so deep in the core is a ball of partially degenerate matter that I think would at least attenuate, and perhaps block outright, the few seconds of lethal neutrino flux, so if you got in that "neutrino shadow" of Jupiter's core and stayed there for the minute or so it mattered, it wouldn't kill you. Presumably you could then use the hour or three while the shock hadn't made it to the surface yet so you could flee the system in relative safety. Mind you, if the weak force reaches out and kills you by its lonesome -- pure electron-neutrino scattering -- then you are in a Very Bad Place.
