Photons entangled to make new form of light

• arclein

Normally, a stream of single photons would exit the cloud at random intervals, but in this case, they were seen to emerge in groups of two and three. Not only were the photons exhibiting attraction, but they'd actually gained mass ?" only that of a fraction of an electron, but that's a leap for a normally weightless particle. Gaining mass also slowed down their speed, making them about 100,000 times slower than the speed of light they'd normally travel at.
