You all must know that the maximum temperature that can support Bose-Einstein Condensate (BEC) formation is proportional to the mass of the particle that comprises the BEC ensemble.
The details of this realization are new to me and are a result of research into the subject matter in this thread. For example, the photon can form BEC at very high temperatures; the electron is not far behind. The proton can also form a BEC at room temperature being relatively lite. Atoms are very massive. They require low temperatures to form a BEC. The question in my mind is what particle is forming a BEC discussed in this thread?
