Dark Stars May Explain Cosmic Gravitational Wave Hum and Early Black Hole Growth

In the faint radio pulses of distant neutron stars, astronomers may be hearing an echo from the universe's first moments — the gravitational afterglow of hypothetical 'dark stars' that collapsed billions of years ago and planted the seeds of the cosmos's largest black holes. A team of researchers proposes that these exotic objects, powered not by nuclear fire but by self-annihilating dark matter, could explain both a mysterious gravitational wave hum detected in 2023 and the puzzling existence of supermassive black holes that appear fully formed in a universe too young to have built them.
