- Mirror photon
-
The mirror photon is the mirror counterpart of the photon. It may be massless or massive in theory.[1] Mirror photons and other mirror matter particles have been proposed as a candidate for dark matter. The mirror photon is also invisible and undetectable, except for their gravitational effects. According to Bob Holdom, of the University of Toronto, says that photons and mirror photons, (along with other particles and their mirror counterparts) can change into each other through the exchange of a "Holdom force" particle, or H particle. Mirror photons, in theory, can interact with regular photons. However, the mirror photon can not interact with any charged particle, it can only interact with its neutral counterpart, the regular photon. A mirror photon can decay into two separate particles, a mirror electron and a mirror positron. These two particles quickly combine to form mirror ortho-positronium. Since mirror particles and mirror photons have the same gravitational properties of regular matter, they could form mirror planets or mirror stars. A mirror star would continually emit mirror photons, and not only would the mirror photons be undetectable, the mirror star, being made out of mirror matter, would be undetectable too, except for its gravitational pull.
Other Characteristics
If massless, a mirror photon would have the same speed as a regular photon. Mirror photons and mirror matter both feel the force of gravity, as gravity is part of spacetime. Aside from the aforementioned characteristics, a mirror photon is the same as a regular photon.[2]
