Study rules out initially clustered primordial black holes as dark matter candidates
Primordial black holes (PBHs) are fascinating cosmic bodies that have been widely investigated by astrophysicists worldwide. As suggested by their name, these are black holes believed to have appeared in the universe's early ...
If wormholes exist, they might magnify light by 100,000 times
A small team of astrophysicists affiliated with several institutions in China has found evidence that suggests if wormholes are real, they might magnify light by 100,000 times. In their paper published in the journal Physical ...
Number of known black holes expected to double in two years with new detection method
Researchers from the University of Waterloo have developed a method that will detect roughly 10 black holes per year, doubling the number currently known within two years, and it will likely unlock the history of black holes ...
