Actually, it turns out that the explosion from one gram of antimatter annihilating would be roughly equivalent to a sixty kiloton nuclear warhead detonating. While antimatter annihilations release a tremendous amount of energy, a significant amount of that energy is lost as neutrinos.
So we'll all die of radiation posioning?
That's correct. The only difference between an antimatter explosion and a conventional nuclear explosion is that the antimatter explosion does not leave radioactive fallout behind. On the other hand, the gamma rays emitted by the explosion may result in photodisintegration of some nearby atoms, resulting in a very short lived burst of radioactivity.
OK... wait is 60 kilotons enough to cause fusion of the nitrogen within our atsmosphere? If so then we're all fired chicken nuggets
While the nitrogen within a meter or two may fuse, the reaction can't sustain itself due to the atmosphere being thin. As for sixty kilotons, that's roughly four times the strength of the bomb that devastated Hiroshima.
Back on topic:
Fortunately it turns out that I am so far away from the laser that the beam is no longer dangerously powerful, due to scattering.
Attack?
bowserinator:
I was wearing really reflective sun glasses and reflect the laser into feynman's eye's
The next user was feynman
EDIT: The next user is a piece of bacon about to be eaten for breakfast.
A very small amount of it - so small as to be non-lethal.
The next user is melted.
