Echoes of Creation: The Roman Telescope’s Quest for Primordial Black Holes

NASA’s Nancy Grace Roman Space Telescope might reveal previously undetected “featherweight” black holes with masses similar to Earth’s. These primordial black holes, formed in the early universe, could significantly impact our understanding of astronomy and particle physics, potentially explaining some of the dark matter in the universe.

Astronomers have discovered black holes ranging from a few times the Sun’s mass to tens of billions. Now a group of scientists has predicted that NASA’s Nancy Grace Roman Space Telescope could find a class of “featherweight” black holes that has so far eluded detection.
