Scientists predict NASA’s Roman Space Telescope could potentially discover mysterious “featherweight” black holes that have eluded detection. These primordial black holes, possibly as light as the Earth, may have formed in the early universe’s chaotic moments, offering groundbreaking insights into physics and astronomy. Observations hint at hidden Earth-mass objects in our galaxy, challenging existing planet formation theories. While identifying these objects poses challenges, Roman’s power could differentiate between Earth-mass black holes and rogue planets, shedding light on dark matter mysteries. These findings could revolutionize our understanding of the early universe, cosmic history, and the universe’s dark matter content.
