Once again...a failed attempt of man trying to pry into the Mysteries of the Creator & His Creation come up short...
"For years, some physicists have rowed against the tide, controversially claiming that they’ve found the universe’s elusive dark matter, despite mounting evidence to the contrary. A new experiment makes that upstream paddling even more of a challenge.
Observations of the cosmos indicate that an invisible, unknown type of subatomic particle must pervade the universe. The extra mass this dark matter provides is necessary to explain the motions of stars within galaxies and how matter clumps together in the universe.
The DAMA/LIBRA experiment, at Italy’s Gran Sasso National Laboratory near L’Aquila, is the one outlier; researchers there say that they have strong evidence that dark matter is interacting in their detector. Now an experiment called COSINE-100 has searched for the particles using the same type of detector as DAMA, and found no signs of dark matter.
So the DAMA team monitored their crystals for years to tease out the purported dark matter signature. The researchers reported that the rate of collisions in the DAMA detector rises and falls with a specific annual pattern. That pattern, the argument goes, is the result of Earth’s motion through a stream of dark matter as the planet orbits the sun.
The sticking point, however, was that those experiments were using a different detector material, rather than sodium iodide crystals. Now, by using the same detector material, “we’re going to take out any possible loophole as to why DAMA sees something,” says Yale University physicist Reina Maruyama.
Instead of looking for annual variation, COSINE-100 researchers compared the rate of hits in their detector, located in the Yangyang Underground Laboratory in South Korea, with the number expected from known sources, such as radioactivity. The team found no sign of extra blips that could be from dark matter."
