Dark Matter is the non-luminous matter that is thought to make up about 85% of the cosmos but it is one of the most elusive substances in the Universe. In an attempt to find answers to this cosmic mystery, researchers from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and UC Berkeley have suggested a “new path”.

As the name suggests, dark matter is not directly detectable. But, scientists have been able to study this elusive substance through its gravitational effect on other astronomical bodies. Now, in the new study, scientists have described a way to directly detect dark matter. They describe how signals generated due to absorption of energy from dark matter particles into atomic nuclei can be used to observe dark matter.

There have been previous experiments that aimed to look for tiny flashes of light produced due to scattering – a process in which dark matter particles collide with atomic nuclei. But scientists think that the process can cause an atom to eject particles like an electron that is full of energy and negligible mass. The absorption can even produce other types of signals due to the ejection of other particles.

Scientists focused on particular cases that involved an electron or a neutrino (subatomic particles that are similar to an electron but with a neutral charge) being ejected from an atom’s nucleus. In their study published in Physical Review Letters, scientists have suggested how experiments can be enhanced to detect the signals related to absorption of dark matter particles in atomic nuclei. Additionally, researchers also want to revisit previously collected data, in search of possible candidates for dark matter signals.
