Detailed explanation-1: -Subaru Telescope Helps Determine that Dark Matter is not Made Up of Tiny Primordial Black Holes.
Detailed explanation-2: -An international research team including Dr. Surhud More and Dr. Anupreeta More from Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune has ruled out the possibility of primordial black holes being a major constituent of dark matter using Subaru telescope.
Detailed explanation-3: -The term dark matter was coined in 1933 by Fritz Zwicky of the California Institute of Technology to describe the unseen matter that must dominate one feature of the universe-the Coma Galaxy Cluster.
Detailed explanation-4: -By precisely measuring the distribution of X-rays from the hot gas, the astronomers were able to make the best measurement yet of the distribution of dark matter near the center of a galaxy cluster.
Detailed explanation-5: -But the most common view is that dark matter is not baryonic at all, but that it is made up of other, more exotic particles like axions or WIMPS (Weakly Interacting Massive Particles).
