2023’s Biggest Breakthroughs in Physics
In 2023, physicists found the gravitational wave background that’s made by supermassive black hole collisions, teleported quantum energy in the lab, and puzzled over JWST’s potentially cosmology-breaking discoveries. Emily Buder/Quanta...
The Year in Physics
From the smallest scales to the largest, the physical world provided no shortage of surprises this year. By one metric, this year’s biggest physics news happened 80 years ago. Yet...
In a ‘Dark Dimension,’ Physicists Search for the Universe’s Missing Matter
...“allows us to make connections between string theory, quantum gravity, particle physics and cosmology, [while] addressing some of the mysteries related to them,” said Ignatios Antoniadis, a physicist at Sorbonne...
A Quantum Trick Implied Eternal Stability. Now the Idea May Be Falling Apart.
...disorder may not be so easily overcome. It is a truth of both physics and everyday experience that things fall apart. Ice melts. Buildings crumble. Any object, if you wait...
What Is the Nature of Time?
...in the past? And how might quantum physics redefine it in the future? Frank is the Herman Feshbach Professor of Physics at M.I.T., a distinguished professor at Arizona State University,...
What Is Quantum Teleportation?
...fundamental questions, including in condensed matter physics, where we’re trying to understand highly entangled states of quantum matter, and in gravitational physics. This story goes back a long way to...
How Is Flocking Like Computing?
...exhibited. When we first measured these properties, it seemed like the individuals were defying the laws of physics. The information was percolating so quickly. And in the, sort of, early...
Dark Energy May Be Weakening, Major Astrophysics Study Finds
...slightly weakening with time. It’s a finding that has the potential to shake the foundations of physics. “If true, it would be the first real clue we have gotten about...
Can Information Escape a Black Hole?
...with it is, it violates a principle of physics. The principle of physics is “nothing ever gets completely lost.” You say, well, that’s crazy. If I take a piece of...
