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 ...

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 ...

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 ...

From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens ...

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

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 ...

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

Earth rotates, the Sun rotates, the Milky Way rotates – and a new model suggests the entire Universe could be rotating. If confirmed, it could ease a significant tension in cosmology. So for a new ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

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 ...
