Engine Black Holes: The Most Massive Objects in the Universe

August 2, 2026 · 30 min

Show notes

Lying at the cores of most large galaxies, do we find the “largest” type of object in the universe- a supermassive “engine” black hole. They almost always have masses many millions of times that of the sun, while the biggest grow to tens of billions. Exactly what was responsible for seeding these great engines, and building up their immense sizes, is a challenge only the James Webb Telescope can rise to.
