Light Molecules.
We all know that light is a massless wave_particle that doesn't interact much with its surrounding, not until recently. Scientists fired a laser through ultracold "rubidium" atoms and the photons came out the other side in pairs and triples. The strength of the photonic bonds were measured based on its oscillation frequency. But this news is a not so new news! In 2013, scientists fired blue laser at ultracold rubidium gas cloud and formed photonic molecules in pairs. The only difference is that now, the molecules were formed in trios! Scientists even believe that the bond of the trios are stronger than that of the pairs. To explain how this works, scientists believe that as photons travel through the rubidium cloud, they are captured temporarily by the rubidium atoms, forming an atom_photon hybrid called the "Rydberg polariton". The photon then travels through the cloud repeating the process and if two or more of this atom_photon hybrid c...
