flag A massive, dormant black hole found in an early galaxy challenges theories on black hole growth.

flag Researchers have discovered a massive, dormant black hole in a galaxy just 800 million years after the Big Bang using the James Webb Space Telescope. flag The black hole, weighing about 400 million times the mass of our Sun, accounts for 40% of its galaxy's mass, challenging current models of black hole growth. flag This suggests black holes may experience rapid growth spurts followed by long periods of inactivity. flag The findings, published in Nature, could provide new insights into early universe black hole development.
