New Maps of the Bizarre, Chaotic Space-Time Inside Black Holes
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
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
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
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
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
The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information.
Where Do Space, Time and Gravity Come From?
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
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
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.”
