New Maps of the Bizarre, Chaotic Space-Time Inside Black Holes

February 24, 2025

Physicists hope that understanding the churning region near singularities might help them reconcile gravity and quantum mechanics.

If the Universe Is a Hologram, This Long-Forgotten Math Could Decode It

September 25, 2024

A 1930s-era breakthrough is helping physicists understand how quantum threads could weave together into a holographic space-time fabric.

The Two Faces of Space-Time

September 25, 2024

A mysterious phenomenon known as duality often leads to new discoveries in physics. This time, space-time itself can sometimes be two things at once.

Quantum Complexity Shows How to Escape Hawking’s Black Hole Paradox

August 2, 2023

Inside of a black hole, the two theoretical pillars of 20th-century physics appear to clash. Now a group of young physicists think they have resolved the conflict by appealing to the central pillar of the new century — the physics of quantum information.

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.

Physicists Create a Holographic Wormhole Using a Quantum Computer

November 30, 2022

The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information.

Where Do Space, Time and Gravity Come From?

May 4, 2022

Einstein’s description of curved space-time doesn’t easily mesh with a universe made up of quantum wavefunctions. Theoretical physicist Sean Carroll discusses the quest for quantum gravity with host Steven Strogatz.

Pondering the Bits That Build Space-Time and Brains

April 20, 2022

Vijay Balasubramanian investigates whether the fabric of the universe might be built from information, and what it means that physicists can even ask such a question.

Symmetries Reveal Clues About the Holographic Universe

January 12, 2022

Physicists have been busy exploring how our universe might emerge like a hologram out of a two-dimensional sheet. New clues have come from the symmetries found on an infinitely distant “celestial sphere.”
