### How (Relatively) Simple Symmetries Underlie Our Expanding Universe

Although Einstein’s theory of space-time seems more complicated than Newtonian physics, it greatly simplified the mathematical description of the universe.

### How Our Universe Could Emerge as a Hologram

Physicists have devised a holographic model of “de Sitter space,” the term for a universe like ours, that could give us new clues about the origin of space and time.

### How Space and Time Could Be a Quantum Error-Correcting Code

The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.

### New Studies Rescue Gravitational-Wave Signal From the Noise

Two independent papers vanquish lingering doubts about LIGO’s historic discovery of gravitational waves.

### Why Black Hole Interiors Grow (Almost) Forever

The renowned physicist Leonard Susskind has identified a possible quantum origin for the ever-growing volume of black holes.

### Quanta Writers and Editors Discuss Trends in Science and Math

On November 16, 2018, more than 200 readers joined writers and editors from *Quanta Magazine* for a wide-ranging panel discussion that examined the newest ideas in fundamental physics, biology and mathematics research.

### How Holography Could Help Solve Quantum Gravity

In the latest campaign to reconcile Einstein’s theory of gravity with quantum mechanics, many physicists are studying how a higher dimensional space that includes gravity arises like a hologram from a lower dimensional particle theory.

### The Peculiar Math That Could Underlie the Laws of Nature

New findings are fueling an old suspicion that fundamental particles and forces spring from strange eight-part numbers called “octonions.”

### Mathematicians Disprove Conjecture Made to Save Black Holes

Mathematicians have disproved the strong cosmic censorship conjecture. Their work answers one of the most important questions in the study of general relativity and changes the way we think about space-time.
