Stars alone can’t explain black holes, JWST data reveals
<p>Today, even the most massive of the known black holes represent only about 0.1% of the stellar mass of the galaxy: just one-thousandth of the amount of mass found by summing up all the stars in the galactic environment surrounding it. For a long time, astronomers have wondered just how these supermassive black holes came to be: did they form from earlier generations of stars, or was something else needed to explain them?
