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

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 ...

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

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

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 ...

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

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 ...

Using the world's most powerful particle accelerator, the Large Hadron Collider, scientists have found that the quark-gluon ...

Astronomers found evidence that dark matter and neutrinos may interact, hinting at a "fundamental breakthrough" that challenges our understanding of how the universe evolved.

Astronomers may have finally cracked one of the universe’s biggest mysteries: how black holes grew so enormous so fast after ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...
