Physicists propose a new theory to explain one dimensional quantum liquids formation

One dimensional quantum lattice liquids. Credit: I. Morera et al. Phys. Rev. Lett Liquids are ubiquitous in Nature: from the water that we consume daily to superfluid helium which is a quantum liquid appearing at temperatures as low as only a few degrees above the absolute zero. A common feature of these vastly different liquids […]

How the Earth-shaking theory of plate tectonics was born

Some great ideas shake up the world. For centuries, the outermost layer of Earth was thought to be static, rigid, locked in place. But the theory of plate tectonics has rocked this picture of the planet to its core. Plate tectonics reveals how Earth’s surface is constantly in motion, and how its features — volcanoes, […]

Theory describes quantum phenomenon in nanomaterials — ScienceDaily

Theoretical physicists Yoshimichi Teratani and Akira Oguri of Osaka City University, and Rui Sakano of the University of Tokyo have developed mathematical formulas that describe a physical phenomenon happening within quantum dots and other nanosized materials. The formulas, published in the journal Physical Review Letters, could be applied to further theoretical research about the physics […]

Unique prediction of ‘modified gravity’ challenges dark matter theory

The best example is represented by the Sunflower galaxy (NGC 5055) with the strongest external fieldamong SPARC galaxies, whose well-measured rotation curve shows a mildly declining behavior at largeradial distance and can be accurately modeled only with an external field effect.

Black holes may not exist, but fuzzballs might, wild theory suggests

Black holes are, by far, the most mysterious objects in the universe. They are objects in the cosmos where all of our knowledge of physics completely breaks down.  And yet, despite their apparent impossibility, they exist. But what if these gravitational monsters aren’t black holes at all, but rather the cosmic equivalent of fuzzy, vibrating […]

CU Anschutz researcher offers new theory on `Venus’ figurines

AURORA, Colo. (Dec. 1, 2020) – One of world’s earliest examples of art, the enigmatic `Venus’ figurines carved some 30,000 years ago, have intrigued and puzzled scientists for nearly two centuries. Now a researcher from the University of Colorado Anschutz Medical Campus believes he’s gathered enough evidence to solve the mystery behind these curious totems. […]

JFK conspiracy theory is debunked in Mexico 57 years after Kennedy assassination

Most conspiracy theories surrounding President John F. Kennedy’s assassination have been disproven. Kennedy was not killed by a gas-powered device triggered by aliens or by actor Woody Harrelson’s dad. But speculation about Kennedy’s Nov. 22, 1963 murder in Dallas continues, fueled by unreleased classified documents, bizarre ballistics and the claim of assassin Lee Harvey Oswald – who was later killed […]
