If true, the idea would blow past one of physics’ most sacred limits: that parallel versions of reality can never talk to ...

A new theoretical framework released today proposes that the vacuum of space is not a smooth void, but a geometrically structured medium with a finite information density. The  Selection-Stitch Model ...

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

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure ...

When the universe first burst into being, all of space was a cosmic cauldron filled with a roiling, fiery liquid of ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

Physicists suggest that a single, extraordinarily powerful cosmic signal detected on Earth could be linked to the explosive end of a tiny black hole from the early universe. That signal now stands as ...

The brightest quasar ever seen in the young cosmos is powered by a black hole that appears to be breaking the universe’s own ...

Across the quiet darkness of space and the buried detectors under Antarctic ice, a set of stubborn anomalies is piling up.

Most of the universe is made of dark matter and dark energy, yet scientists still don’t know what either one is. New ultra-sensitive detectors are being built to spot incredibly rare particle ...

As the Dark Energy Survey (DES) releases its final results, we caught up with two physicists who've been involved in the ...
