Puzzling Quantum Scenario Appears Not to Conserve Energy
...be an expression of the fundamental symmetries of the universe — a “very important part of the edifice of physics,” said Chiara Marletto, a physicist at the University of Oxford....
Diminishing Dark Energy May Evade the ‘Swampland’ of Impossible Universes
...physics, which has long predicted that space should be suffused with substantial amounts of energy. The quantum fields that permeate space fluctuate in strength, never staying exactly at zero; particles...
Dark Matter Experiment Finds Unexplained Signal
Researchers say there are three possible explanations for the anomalous data. One is mundane. Two would revolutionize physics. The physicists who run the world’s most sensitive experimental search for dark...
What Is Entropy? A Measure of Just How Little We Really Know.
...and why the world appears deterministic rather than quantum mechanically uncertain. But despite its fundamental importance, entropy is perhaps the most divisive concept in physics. “Entropy has always been a...
Neutrinos Lead to Unexpected Discovery in Basic Math
...to compute. Moreover, they realized that the relationship between eigenvectors and eigenvalues — ubiquitous objects in math, physics and engineering that have been studied since the 18th century — seemed...
Does Natural Law Need Elegant Mathematics?
...of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve.” Similar thoughts have been...
Juan Maldacena, Pondering Quantum Gravity by the Pond
...or out — in clearing a path to inspiration. As a young professor at Harvard University in 1997, Juan Maldacena reshaped fundamental physics with the discovery that, as he put...
If the Universe Is a Hologram, This Long-Forgotten Math Could Decode It
...the tantalizing possibility that physicists could do an end run around physics they don’t understand (quantum gravity in the bulk) by using only physics they do understand (quantum field theory)....
Wormhole Experiment Called Into Question
...the work was one of the hotter trends in modern physics, holography. Holography involves the study of profound relationships known as dualities. On their face, dual systems look completely different....
