Q&A

The Physicist Who’s Challenging the Quantum Orthodoxy

July 10, 2023

For decades, physicists have struggled to develop a quantum theory of gravity. But what if gravity — and space-time — are fundamentally classical?

In New Paradox, Black Holes Appear to Evade Heat Death

June 6, 2023

The puzzling behavior of black hole interiors has led researchers to propose a new physical law: the second law of quantum complexity.

Q&A

The Physicist Who Glues Together Universes

May 25, 2023

Renate Loll has helped pioneer a radically new approach to quantum gravity. She assumes that the fabric of space-time is a blend of all possible fabrics, and she has developed the computational tools needed to calculate the far-reaching implications of that assumption.

Physicists Create Elusive Particles That Remember Their Pasts

May 9, 2023

In two landmark experiments, researchers used quantum processors to engineer exotic particles that have captivated physicists for decades. The work is a step toward crash-proof quantum computers.

A New Kind of Symmetry Shakes Up Physics

April 18, 2023

So-called “higher symmetries” are illuminating everything from particle decays to the behavior of complex quantum systems.

The Electron Is So Round That It’s Ruling Out Potential New Particles

April 10, 2023

If the electron’s charge wasn’t perfectly round, it could reveal the existence of hidden particles. A new measurement approaches perfection.

How to Tame the Endless Infinities Hiding in the Heart of Particle Physics

April 6, 2023

In the math of particle physics, every calculation should result in infinity. The set of techniques known as “resurgence” points toward an escape.

Wormhole Experiment Called Into Question

March 23, 2023

Last fall, a team of physicists announced that they had teleported a qubit through a holographic wormhole in a quantum computer. Now another group suggests that’s not quite what happened.

Black Holes Will Eventually Destroy All Quantum States, Researchers Argue

March 7, 2023

New calculations suggest that the event horizons around black holes will ‘decohere’ quantum possibilities — even those that are far away.
