Physicists Reveal a Quantum Geometry That Exists Outside of Space and Time. By Charlie Wood. September 25, 2024. A decade after the discovery of the “amplituhedron,” physicists have excavated more of the timeless geometry underlying the standard picture of how particles move. fundamental physics.
How Earth’s Climate Changes Naturally (and Why Things Are …
Jul 21, 2020 · Earth’s climate has fluctuated through deep time, pushed by these 10 different causes. Here’s how each compares with modern climate change. Orbital wobbles, plate tectonics, evolutionary changes and other factors have sent the planet in and out of ice ages. Pablo A. Cumillaf. Earth has been a snowball and a hothouse at different times in ...
The Mystery at the Heart of Physics That Only Math Can Solve
Jun 10, 2021 · The accelerating effort to understand the mathematics of quantum field theory will have profound consequences for both math and physics. Olena Shmahalo/Quanta Magazine. Over the past century, quantum field theory has proved to be the single most sweeping and successful physical theory ever invented. It is an umbrella term that encompasses many ...
Physicists Use Quantum Mechanics to Pull Energy out of Nothing
Feb 22, 2023 · The new quantum protocol effectively borrows energy from a distant location and thus violates no sacred physical principles. Kristina Armitage/ Quanta Magazine. For their latest magic trick, physicists have done the quantum equivalent of conjuring energy out of thin air. It’s a feat that seems to fly in the face of physical law and common sense.
What Is Quantum Teleportation? - Quanta Magazine
Mar 14, 2024 · In this episode, Janna Levin interviews the theoretical physicist John Preskill about teleporting bits and the promise of quantum technology. Quantum teleportation isn’t just science fiction; it’s entirely real and happening in laboratories today. But teleporting quantum particles and information is a far cry from beaming people through ...
A New Map of All the Particles and Forces | Quanta Magazine
Oct 22, 2020 · We’ve created a new way to explore the fundamental constituents of the universe. Ashley Mackenzie for Quanta Magazine. [Editor’s note: The full, interactive map is available below.] All of nature springs from a handful of components — the fundamental particles — that interact with one another in only a few different ways.
How the Physics of Resonance Shapes Reality | Quanta Magazine
Jan 26, 2022 · Here’s how the same effect manifests in such varied settings, from everyday life down to the smallest scales. In its simplest form, resonance occurs when an object experiences an oscillating force that’s close to one of its “natural” frequencies, at which it easily oscillates. That objects have natural frequencies “is one of the ...
The Most Famous Paradox in Physics Nears Its End
Oct 29, 2020 · The work appears to resolve a paradox that Stephen Hawking first described five decades ago. Ashley Mackenzie for Quanta Magazine. In a series of breakthrough papers, theoretical physicists have come tantalizingly close to resolving the black hole information paradox that has entranced and bedeviled them for nearly 50 years.
A New Physics Theory of Life - Quanta Magazine
Jan 22, 2014 · An MIT physicist has proposed the provocative idea that life exists because the law of increasing entropy drives matter to acquire lifelike physical properties. Jeremy England, a 31-year-old physicist at MIT, thinks he has found the underlying physics driving the origin and evolution of life. Katherine Taylor for Quanta Magazine.
A Mathematician’s Guided Tour Through High Dimensions
Sep 13, 2021 · The formal study of higher dimensions emerged in the 19th century and became quite sophisticated within decades: A 1911 bibliography contained 1,832 references to the geometry of n dimensions. Perhaps as a consequence, in the late 19th and early 20th centuries, the public became infatuated with the fourth dimension.
