> The apparent vanishing of particles in one place at one time—and their reappearance in other times and places—suggests [...] a particle’s presence in one place is somehow “canceled” by its own “counterparticle” in the same location. [...] These putative counterparticles should possess negative energy and negative mass, allowing them to cancel their counterparts. I thought negative energies in Quantum Mechanics give rise to senseless infinities that can't be eliminated. What gives?
