How the Higgs Field (Actually) Gives Mass to Elementary Particles
...physics, says the universe is filled with fields. Examples include the electromagnetic field, the gravitational field and the Higgs field itself. For each field, there’s a corresponding type of particle,...
Do We Need a New Theory of Gravity?
...is a professor of theoretical physics and the deputy head of the physics department at Imperial College London. Her research lies at the intersection of particle physics, gravity and cosmology....
Computer Scientists Prove That Heat Destroys Quantum Entanglement
...physics compete with the laws of thermodynamics, and things get messy. At very low temperatures, entanglement can spread over long distances, enveloping many atoms and giving rise to strange phenomena...
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...
‘Metaphysical Experiments’ Probe Our Hidden Assumptions About Reality
...where previous work in physics let its metaphysics go unacknowledged, in Bell’s work the two were truly and explicitly inseparable. The theorem was not about any particular theory of physics....
The Physics of Cold Water May Have Jump-Started Complex Life
...be due to the physics of cold water. A Frozen Paradox “Snowball Earth” was on everyone’s lips when Simpson was an undergraduate in the late 1990s. In 1992, the geochemist...
What Could Explain the Gallium Anomaly?
...physics: the gallium anomaly. “I think it’s one of the most compelling anomalies in neutrino physics that we have today,” said Ben Jones, a neutrino physicist at the University of...
How Is Science Even Possible?
...and physics is so powerful in its explanations makes another assumption. That assumption is reductionism. This goes back to another quote of another founder of modern physics, Paul Dirac, who...
Cryptographers Discover a New Foundation for Quantum Secrecy
...to information security in the 1980s, a few researchers discovered that computational hardness wasn’t the only way to safeguard secrets. Quantum theory, originally developed to understand the physics of atoms,...
