The Physicist Who Glues Together Universes
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
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.
How to Tame the Infinities Hiding in the Heart of Particle Physics
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
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.
Room-Temperature Superconductor Discovery Meets With Resistance
A paper in Nature reports the discovery of a superconductor that operates at room temperatures and near-room pressures. The claim has divided the research community.
Physicists Use Quantum Mechanics to Pull Energy out of Nothing
The quantum energy teleportation protocol was proposed in 2008 and largely ignored. Now two independent experiments have shown that it works.
How Our Reality May Be a Sum of All Possible Realities
Richard Feynman’s path integral is both a powerful prediction machine and a philosophy about how the world is. But physicists are still struggling to figure out how to use it, and what it means.
How Quantum Physicists ‘Flipped Time’ (and How They Didn’t)
Two teams have made photons act as if time were simultaneously flowing in two directions. The experiments demonstrate a way to potentially boost the performance of quantum devices.
Starfish Whisperer Develops a Physical Language of Life
Nikta Fakhri is adapting and extending concepts from physics to describe how tiny biological components give rise to living organisms.
