see, now this is cool
From xkcd: How close would you have to be to a supernova to get a lethal dose of neutrino radiation?
I imagine this is the kind of shit Rodney and Radek talk about at lunch, leaving John scratching his head over his not-fries. It's just brilliant. My favorite bit?
Which of the following would be brighter, in terms of the amount of energy delivered to your retina:
A supernova, seen from as far away as the Sun is from the Earth; or
The detonation of a hydrogen bomb pressed against your eyeball?
(Turns out the answer is the supernova...by nine orders of magnitude!)
