Weird Neutrino Behavior Could Explain Long-standing Antimatter Mystery

But more data are needed before physicists know for sure

Did Astronomers Just Discover Black Holes from the Big Bang?

Gravitational waves attributed to the collision of two neutron stars could have been produced by something much stranger

Supergravity Snags Super Award: $3-Million Special Breakthrough Prize

The theory, which emerged in the 1970s as a way to unify the fundamental forces of nature, has profoundly shaped the landscape of particle physics

Quantum Gravity in the Lab

Physicists attempting to unify the theories of  gravity and quantum mechanics have long thought practical experiments were out of reach, but new proposals offer a chance to test the quantum nature of gravity on a tabletop...

Found: A Quadrillion Ways for String Theory to Make Our Universe

Stemming from the “F-theory” branch of string theory, each solution replicates key features of the standard model of particle physics

Photons, Quasars and the Possibility of Free Will

Flickers of light from the edge of the cosmos help physicists advance the idea that the future is not predetermined

String Theory May Create Far Fewer Universes Than Thought

Some physicists claim that the popular landscape of universes in string theory may not exist

Tangled Up in Spacetime

Hundreds of researchers in a collaborative project called “It from Qubit” say space and time may spring up from the quantum entanglement of tiny bits of information

Newly discovered lobes stretch tens of thousands of light-years above and below the Milky Way's disk. Where did they come from?

Can Time Travelers Reach the Past via Wormholes?

Astronauts already skip ahead in time, but the laws of physics seem to forbid going backward—or do they?

Super Spiral Galaxies Amaze Astronomers

A new breed of giants raises questions about how the biggest galaxies arise

Superstars of the First Galaxies

Emerging evidence suggests that the first starlight to shine after the big bang’s flash came from distant suns that ranged from very large to incredibly huge

The Black Hole at the Beginning of Time

5 Reasons to Thank Your Lucky Constants This Thanksgiving

As you dig into those mashed potatoes, be grateful the universe’s physical constants are so precise that a slight variation in any one would render that drumstick—and even your existence—impossible...

Mars May Become a Ringed Planet Someday

A collision between the Red Planet and its innermost moon, Phobos, could create a Saturn-like field of debris
