'cause suppose even if I consider the initial thermal(etc.) energy of the fissionable mass =e1 and kinetic energy of the striking nuclear projectile(poton etc.) to be =e2...


then i don think that E3=energy produced by nuclear fission(heat+electromagnetic) is in any way near the sum of e2 & e1??!!!
i.e E3>>>e1+e2

so here the law of consv. of mass-energy holds,but does it mean that we can practically increase the total energy of the universe by a finite value?????

reply fast n plz give req. exp. facts.......
