The upcoming sci-fi film hits theaters in June 2026

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing that idea is challenging.

For years, the James Webb Space Telescope has been spotting enormous black holes in the early universe that defy all expectations. Now, astronomers are finally deciphering the origins of these cosmic behemoths.

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen.

At 3.3 billion light-years across, the ring may challenge the “cosmological principle” that the universe looks uniform at sufficiently large scales.

Astronomers realized that a strange cloud of gas was actually a relic of the ancient universe which might help solve some of space's greatest mysteries.
