The only problem is that use of such a weapon could possibly destroy the universe as we know it in the event of a malfunction, so their use would probably be highly restricted.
You know i swear to god some of these articles scare the fricking boxers out of me ! So dont let me see them when i'm at work or il get dragged to a lawsuit because of indecent exposure (basicly il make the other ladies around ehre cheat on theyr boyfriends/huisbands (dont believe me its just my braing gooing kaboom after the said article ) !
But then again wtf are these guis tring to study over there? Hell do they even understand 100% of the stuff that happenes there or are thy just asuming they know???
Also if beams work in any way as a particle accelerator they should be able to hit targets at masive distances not just 4 km. Also projecting matter at a relativistic speed (im asuming relativistic speeds in the artivle means near the speed of light) would cause the said matter to acumulate infinite mass . By gaining infinite mass it would gain infinite gravity or something similar to a black hole of the sorts.
This is just something off the top of my devastetad brain whych a proffesor of mine (phisics of course
) tried to explain.
Also since im not 100% sure of his actual explanation this could be wrong. However i do remember very clear that i was arguing with him about the theory of relativity sayng basicly that it has to be wrong. Because if that were the case then light particles wich has been proven have mass should in theory becaome well sort of like a black hole or something. Or rather miniature black holes.
Some of them science geniuses here that got more then a 5 or 6 at math and phisics get here and smash my theory to pieces and post a correct one pls

Thanx you guis are too kind
