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.

Are There Reasons to Believe in a Multiverse?

May 17, 2023

Several areas of physics suggest reasons to think that unobservable universes with different natural laws could lie beyond ours. The theoretical physicist David Kaplan talks with Steven Strogatz about the mysteries that a multiverse would solve.

New Proof Finds the ‘Ultimate Instability’ in a Solar System Model

May 16, 2023

For the first time, mathematicians have proved that planetary orbits in a solar system will always be unstable.

The Tiny Physics Behind Immense Cosmic Eruptions

May 15, 2023

A new theory describes how particle interactions fuel fast magnetic reconnection, the process behind solar flares and other astrophysical jets.

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 Idea for How to Assemble Life

May 4, 2023

If we want to understand complex constructions, such as ourselves, assembly theory says we must account for the entire history of how such entities came to be.
