Mirror photon
Encyclopedia
The mirror photon is the mirror counterpart of the photon. It may be massless or massive in theory.http://adsabs.harvard.edu/abs/1994hep.ph....7331F 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 photon
s 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 charge
d 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.

Mirror matter
In physics, mirror matter, also called shadow matter or Alice matter, is a hypothetical counterpart to ordinary matter.Modern physics deals with three basic types of spatial symmetry: reflection, rotation and translation. The known elementary particles respect rotation and translation symmetry but...

Dark matter
In astronomy and cosmology, dark matter is matter that neither emits nor scatters light or other electromagnetic radiation, and so cannot be directly detected via optical or radio astronomy...

Photon
In physics, a photon is an elementary particle, the quantum of the electromagnetic interaction and the basic unit of light and all other forms of electromagnetic radiation. It is also the force carrier for the electromagnetic force...

Charge (physics)
In physics, a charge may refer to one of many different quantities, such as the electric charge in electromagnetism or the color charge in quantum chromodynamics. Charges are associated with conserved quantum numbers.-Formal definition:...
d particle, it can only interact with its neutral counterpart, the regular photon. A mirror photon can decay into two separate particles, a mirror electron
Electron
The electron is a subatomic particle with a negative elementary electric charge. It has no known components or substructure; in other words, it is generally thought to be an elementary particle. An electron has a mass that is approximately 1/1836 that of the proton...

Positron
The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. The positron has an electric charge of +1e, a spin of ½, and has the same mass as an electron...

Spacetime
In physics, spacetime is any mathematical model that combines space and time into a single continuum. Spacetime is usually interpreted with space as being three-dimensional and time playing the role of a fourth dimension that is of a different sort from the spatial dimensions...
