Astronomers Creep Up to the Edge of the Milky Way’s Black Hole
...— is spinning not far from the innermost orbit allowed by the laws of physics. If so, this affords astronomers their closest look yet at the funhouse-mirrored space-time that surrounds...
Mixing Is the Heartbeat of Deep Lakes. At Crater Lake, It’s Slowing Down.
The physics of mixing water layers — an interplay of wind, climate and more — makes lakes work. When it stops, impacts can ripple across an ecosystem. On a radiant...
Physicists Hunt for the Big Bang’s Triangles
...physics. So goes the story of cosmic inflation, the modern version of the Big Bang theory. That single short, outrageous growth spurt fits all existing cosmological data well and accounts...
Is Dark Energy Getting Weaker? New Evidence Strengthens the Case.
...finding, presented today at the Global Physics Summit in Anaheim, California, aligns with that of a second group of cosmologists, the 400-strong Dark Energy Survey (DES). Having also observed a...
A New Theory for Systems That Defy Newton’s Third Law
...systems are elegantly described with statistical mechanics, the branch of physics that explains how collections of objects behave. This allows researchers to fully model the conditions that give rise to...
Theory of Fluids Enters the 21st Century
...up. In the second half of the 20th century, a conceptual tsunami swept through physics. The discovery that our world emerges from a microscopic world of molecules, which emerges from...
Newfound Wormhole Allows Information to Escape Black Holes
...an intriguing talk at the Strings conference in South Korea. The speaker, Juan Maldacena, a professor of physics at the Institute for Advanced Study in Princeton, New Jersey, had recently...
A New Experiment Casts Doubt on the Leading Theory of the Nucleus
...theorist at the French National Center for Scientific Research, said Bacca and her colleagues have exposed a significant problem in nuclear physics. They’ve found, he said, an instance where our...
How the Universe Got Its Bounce Back
...ways that bounces could conceivably occur. One of the models, described in a paper that will appear in the Journal of Cosmology and Astroparticle Physics, comes from Anna Ijjas of...
