Ancient quasars seen by the James Webb Space Telescope technically shouldn’t exist, but one rare type of dark matter could make sense of that. Ultra-self-interacting dark matter clumped into ...

A groundbreaking new study proposes that black holes, which absorb everything into an inescapable void, may eventually transition into “white holes” that eject matter and energy into the cosmos.

"When we do observational measurements to understand which cosmological model describes our universe, we generally make the well-justified assumption that the universe is approximately homogeneous ...
