Cyber Monday may be behind us, but there are still a few deals to be had. We've rounded up the remaining bargains, so snap these up before they're gone!
Suppose you slammed together two neutrons at near-luminous speed. The resulting collision would create a cascade of particles from protons, electrons, and neutrinos to more exotic fare. We can't predict the exact number or type of particles produced, but we do know one thing: the total charge of all the particles would be zero. This is because charge is a conserved quantity, and since the neutrons have zero total charge, their resulting particles must have the same.
