Black holes have such extreme gravity that not even light can escape. They have been caught shredding entire stars and can even devour other black holes. And now, one scientist thinks there’s a chance that our universe may have existed unscathed for tens of billions of years inside one super-super-supermassive black hole.

Observations from JADES, the James Webb Space Telescope Advanced Deep Extragalactic Survey, led Lior Shamir—a researcher from Kansas State University—to suggest this out-of-this-world idea. Shamir took a closer look at 263 galaxies seen by JADES, which showed up clearly enough to make out their rotation based on their shapes. He identified that about two thirds of these galaxies as rotating in the opposite direction to the Milky Way is rotating in.
