In the last few weeks, scientists working at the Lawrence Livermore National Laboratory have developed what they call a “stealth dark matter” model, which suggests that dark matter is composed of electrically charged particles bound by a mysterious, unknown force. Through a combination of computer simulations and theoretical results, researchers Pavlos Vranas and colleagues have now developed the model that could help unravel the mystery of why dark matter behaves like it does, what particles make it up, and what force binds them. Crucially, the model offers assumptions that physicists should be able to test using CERN's Large Hadron Collider (LHC) particle accelerator.
The stealth dark matter model predicts that dark matter is stable, but also produces large quantities of electrically charged, unstable nuclear particles. These short-lived particles left a definite mark in the very early universe, with the extremely high plasma temperatures forcing them to interact with ordinary matter. "These interactions in the early universe are important because ordinary and dark matter abundances today are strikingly similar in size, suggesting this occurred because of a balancing act performed between the two before the universe cooled," says Vranas. Dark matter is currently thought by Earth scientists to be completely inert to electromagnetic radiation, so they are amazed to discover that it is in fact composed of electrically charged particles which have somehow managed to avoid detection.

The Sun is the source of the visible light spectrum on our dimension. Another kind of non-luminous ‘matter’ exists on the intelligible plane, as do higher dimensional beings.
