A new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) “little red dots?”

Invisible leviathans lurk at the cores of nearly all of the 2 trillion or so galaxies strewn throughout space-time. Monster black holes entered the cosmic scene soon after the Universe’s birth and grew rapidly, reaching millions or even billions of times the Sun’s mass in less than a billion years. Astronomers have long wondered how these supermassive black holes could have grown so hefty in such little time.

The monster black hole mystery became even more perplexing in 2022 when “ little red dots ” were spotted at the far edges of space. When these tiny scarlet orbs began unexpectedly popping up in JWST images of the distant Universe, their nature was hotly debated. Now that scientists have amassed a sample of hundreds of them , many think the dots are growing supermassive black holes .
