The broken mirror of our universe
The dark sector and its hidden forces

Mirror stars and invisible galaxies
007skaty Self-Interacting Dark Matter
They collide and scatter on their own dark force to smooth out the core
007skaty An active parallel ecosystem explains why dark matter behaves like a fluid during cosmic collisions instead of remaining simple, non-interacting particles.
007skaty Kinetic mixing gives mirror particles one-millionth of a normal electron's electric charge.
007skaty Bend light and shadows to discover how forces behave in a parallel world of matter.
Light mixing: If kinetic mixing is real, highly intense ordinary light sources like lasers or the Sun could be constantly producing a tiny stream of invisible mirror photons.
A hypothetical realm of physics consisting of undetected particles and forces that do not interact via standard electromagnetism. In 1986, physicist Bob Holdom proposed that a dark photon could link this realm to ordinary matter.
What major astronomical observation first led scientists to realize dark matter must exist?
Approximately what percentage of the universe's total mass-energy content is estimated to be dark matter?
What is the name of the process where ordinary and mirror photons slightly mix, allowing a weak connection?
How large is the predicted 'fractional' electric charge of a mirror electron due to kinetic mixing?
What is the hypothetical force carrier that could act as a 'portal' between our world and the mirror world?
