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.
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.
Shadows in the Big Bang Afterglow Reveal Invisible Cosmic Structures
Cosmologists are using secondary signatures from the cosmic microwave background to map the universe’s hidden matter.
Black Holes Will Eventually Destroy All Quantum States, Researchers Argue
New calculations suggest that the event horizons around black holes will ‘decohere’ quantum possibilities — even those that are far away.
Mathematicians Find an Infinity of Possible Black Hole Shapes
In three-dimensional space, the surface of a black hole must be a sphere. But a new result shows that in higher dimensions, an infinite number of configurations are possible.
Standard Model of Cosmology Survives a Telescope’s Findings
Reports that the James Webb Space Telescope killed the reigning cosmological model turn out to have been exaggerated. But astronomers still have much to learn from distant galaxies glimpsed by Webb.
She Turns Fluids Into ‘Black Holes’ and ‘Inflating Universes’
By using fluids to model inaccessible realms of the cosmos, Silke Weinfurtner is “looking for a deeper truth beyond one system.” But what can such experiments teach us?
Physicists Create a Holographic Wormhole Using a Quantum Computer
The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information.
Brightest-Ever Space Explosion Reveals Hints of Dark Matter
A recent gamma-ray burst known as the BOAT — “brightest of all time” — appears to have produced a high-energy particle that shouldn’t exist. For some, dark matter provides the explanation.
