Dark matter is thought to comprise 83 percent of all matter in the universe and, unfortunately for researchers – it is invisible.
New research brings up a new theory that says dark matter used to be highly visible during the hot, early days of the universe. The Lawrence Livermore team found that high-energy particle collider experiments, like those being performed at the Large Hadron Collider in Switzerland, could reveal evidence of dark matter.
Using both theoretical and computational physics methods, the study authors described dark matter as naturally "stealthy" today, but interactions with matter in high-temperature plasma conditions, like those found just after the Big Bang, would reveal this exotic type of 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," said study author Pavlos Vranas, an LLNL quantum physicist.
