How much energy do we need to get a single particle reaching 99.9% the speed of light... and how much energy required to get a single extremely small mass particle to reach the speed of light?
When they send the particles near c wont they get too big to fit in the loop...as we get near c is it not so that mass etc increases dramatically???..so will these particles still be at home in their huge race track??? or in other words to fit the prediction as to how mass will "grow" as c is approached will our accelerated particles "grow" and if so in what way??
