Hayes would like to know what would happen when two equally forceful laser beams, preferably one red and one green from
Star Wars, collide head-on. I talked with Hayes about energy, angle of deflection, etc., and came to the conclusion that they would not repel one another but consume each other. Laser beams not fired directly at one another would bounce off the other and change their directory.
I was able to find
this reference but, alas, it's not exactly what Hayes wanted to know. Does anybody know?
