The Voyage to the End of Ice
...rest of the planet. To nail down the answer, an expedition to the top of the world has to untangle the knotty physics of ice. “Pull out your ice picks,”...
Neutron-Star Collision Shakes Space-Time and Lights Up the Sky
...questions in astrophysics. “In one fell swoop, gravitational wave measurements” have opened “a window onto nuclear astrophysics, neutron star demographics and physics and precise astronomical distances,” said Scott Hughes, an...
The Physicist Who Slayed Gravity’s Ghosts
...their beauty and depth. Einstein built general relativity on some pillars called Einstein’s principles. One is the equivalence principle: The laws of physics surely shouldn’t depend on who’s observing that...
Black Hole Paradoxes Reveal a Fundamental Link Between Energy and Order
...formula says that any changes to the microscopic physics of the gas, such as the type of atoms that comprise it, produce equal and opposite shifts in its energy and...
Strange Solar Gamma Rays Discovered at Even Higher Energies
...dynamics of the cosmic particles winding around them. Beyond solving the gamma-ray mystery, researchers think that the HAWC measurements may lead to broader insights into solar and particle physics. The...
The Physicist Who Glues Together Universes
...work in economics, but I soon got homesick for physics, which I had studied as an undergraduate. Economics is about predicting the behavior of people. High-energy physics, with its fundamental...
How to Make the Universe Think for Us
...compute 3.532 times 1.567 or something,” Scellier said. “It’s done, but implicitly, just by the laws of physics directly.” The Thinking Part McMahon and his collaborators have made progress on...
Scientists Uncover the Universal Geometry of Geology
...needed Jerolmack’s help to show that this is what nature does. “It was geometry with an exact prediction that was borne out in the natural world, with essentially no physics...
The Physicist Who’s Challenging the Quantum Orthodoxy
...acrobatics his peers performed to tackle one of the most notorious problems in modern physics: the black hole information paradox. In 2017, Oppenheim started searching for alternatives that avoided the...
