The strange behavior of the massive merging galaxy cluster could be explained by the collision of dark matter, the universe’s most mysterious substance, with itself. However, the currently most favored model of cosmology is the cold dark matter (CDM) model, which posits that dark matter, which is virtually invisible because it does not interact with… Read More »
Astronomers have discovered one of the most powerful black hole explosions ever seen, and the massive explosion, which occurred almost 4 billion years ago, created a pattern of stars in jewel-like clusters. The starry necklace adorns a massive cluster of hundreds of galaxies called SDSS J1531; This object is located approximately 3.8 billion light years… Read More »
