Physicists speculated about what would happen if you tried to split a photon, and they discovered some anomalous behavior that may transform the way we actually think about particles.

Photons primarily are elementary particles that cannot simply be broken into smaller pieces. Physicists calculate that if you try to split a photon, you wouldn't end up with a fraction of a second photon. 

Meanwhile, researchers reported in a paper accepted by Physical Review Letter, an infinite number of photons would crumble out from the quantum vacuum.

For those unversed, a photon behaves as both a particle and a wave. Researchers........
