In a groundbreaking study, physicists have estimated the minimum mass of a dark matter particle within the dwarf galaxy Leo II.
The research, conducted through the analysis of stellar kinematics in the Milky Way satellite, has yielded a value of 2.2 x 10 electronvolts.
This new estimate, rooted in the fundamental principles of quantum mechanics, marks a significant step forward in understanding the elusive nature of dark matter and its composition of bosons.
