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

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

"We have long treated the Planck scale like a blurry limit," said Kulkarni. "But if you treat space as an information storage medium, geometry dictates a specific packing efficiency. The universe has ...

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 ...

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

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 ...

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 multiverse suggests that our universe may not be unique, but just one of countless others existing beyond our observable reality. Some versions arise naturally from inflation theory and quantum ...

Foundations in science and physics exist at the very core of the Netflix's hit show “Stranger Things," demonstrating to audiences for over a decade that our universe may be "stranger" than we care to ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...
