How the Higgs Field (Actually) Gives Mass to Elementary Particles
Sep 3, 2024 · This notion lies at the heart of what the late British physicist Peter Higgs, namesake of the Higgs field, and his competitors pointed out in the 1960s: that one field can stiffen other fields, thereby permitting their ripples to vibrate in place with a resonant frequency, and thus giving their particles mass.
What Is Quantum Teleportation? - Quanta Magazine
Mar 14, 2024 · Teleporting people through space is still science fiction. But quantum teleportation is dramatically different and entirely real. In this episode, Janna Levin interviews the theoretical physicist John Preskill about teleporting bits and the promise of quantum technology.

New Clues for What Will Happen When the Sun Eats the Earth
Dec 20, 2023 · Earth’s fate rests on a coin flip. In 5 billion years, our sun will balloon into a red giant star. Whether Earth survives is an “open question,” said Melinda Soares-Furtado, an astrophysicist at the University of Wisconsin, Madison.Sure, Earth …
How Earth’s Climate Changes Naturally (and Why Things Are …
Jul 21, 2020 · Faint Young Sun. Magnitude: No net temperature effect. Time frame: Constant. Though the sun’s brightness fluctuates on shorter timescales, it brightens overall by 0.009% per million years, and it has brightened by 48% since the birth of the solar system 4.5 billion years ago.. Scientists reason that the faintness of the young sun should have meant that Earth remained frozen solid for the ...
A New Map of All the Particles and Forces | Quanta Magazine
Oct 22, 2020 · This approach doesn’t offer insight into the relationships between the particles. The force-carrying particles (namely the photon, which conveys the electromagnetic force; the W and Z bosons, which convey the weak force; and the gluons, which convey the strong force) are put on the same footing as the matter particles those forces act …
What Happens in a Mind That Can’t ‘See’ Mental Images
Aug 1, 2024 · These processes were even less defined in 2003, when an articulate and bright 60-year-old man walked into Adam Zeman’s office. Zeman, a neurologist at the universities of Edinburgh and Exeter who studies visual imagery, listened as the patient recounted how, following a cardiac procedure, he could no longer conjure mental images.
High-Temperature Superconductivity Understood at Last
Sep 21, 2022 · The research advances the perennial ambition of the field: to take cuprate superconductivity and strengthen its underlying mechanism, in order to design world-changing materials capable of superconducting electricity at even higher temperatures.
Physicists Create a Wormhole Using a Quantum Computer
Nov 30, 2022 · Editor’s note: In February 2023, a team of physicists led by Norman Yao of Harvard University published a comment about the holographic wormhole experiment described in this article. After analyzing the mathematical properties of the model used to simulate the wormhole in a quantum computer, the group concluded that the teleportation demonstration should not be thought of as a holographic ...
