Why Does Gravity Travel at the velocity of Light?

Two neutron stars collide; the resulting gravitational wave spread at the speed of light. Credit: National Science Foundation/LIGO/Sonoma State University/A. Simonne.The dead cores of 2 stars collided 130 million yrs earlier in a galaxy somewhat far away.The crash was so extreme that it originated a wrinkle in space-time-- a gravitational wave. That gravitational wave...

Physicists Confirm the Existence Of Two-Dimensional Particles Called ‘Anyons’

After decades of exploration in nature's most minor domains, physicists have finally found proof that anyons exist. 1st predicted by theorists in the early 1980s, these particle-like objects arise in realms confined to two dimensions and then under certain circumstances-- like at temperatures near absolute zero and in the existence of a solid magnetic...

Did the scientists at CERN discover proof of completely novel physics?

The detector at the Large Hadron Collider’s CMS experiment, pictured during the machine’s shutdown. Credit: Samuel Joseph Hertzog, Julien Marius Ordan/CERNAfter running for a decade, there were high expectations that the Large Hadron Collider (LHC), the colossal accelerator at CERN, would uncover new particles that could aid in the understanding of the most profound mysteries...

Scientists Develop Small Lens for Trapping Atoms

Graphical illustration of light focusing using a planar glass surface studded with millions of nanopillars (referred to as a metalens) forming an optical tweezer. (A) Device cross section depicts plane waves of light that come to a focus through secondary wavelets generated by nanopillars of varying size. (B) The same metalens is used to...

James Webb Captures New Images of the Cartwheel Galaxy

Image of the Cartwheel Galaxy and its companion galaxies is a composite from Jame Webb’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI). MIRI data is colored red while NIRCam data is colored blue, orange, and yellow.Credit: NASA, ESA, CSA, STScIThe space telescope's powerful infrared gaze offers a new sight of just how the galaxy...

A significant breakthrough has occurred with the successful use of an augmented reality contact lens by a human for the first time.

The latest prototype of Mojo Vision's AR contact lens. Credit: Mojo VisionA human has recently worn an AR contact lens for the first time, which has a pixel thickness approximately 30 times greater than that of a smartphone.A group of people interacted with a combination of real and virtual items three decades ago, using...

How Imaginary Numbers Describe the Fundamental Shape of Nature

Several science students may imagine a ball rolling down a hill or a car skidding due to friction as prototypical examples of the systems physicists care about. However, much of modern physics consists of looking for objects and essentially invisible sensations: the small electrons of quantum physics and the particles concealed within odd steels...

How Long Does it Take to Charge a Tesla?

Tesla models chargingUsing EV (Electrical Vehicles) instead of automobiles powered by internal combustion engines is good for the environment. Nevertheless, the absence of charging terminals and charging times makes people hesitate before getting themselves an electric car.Scientists and companies work together to offer faster charging times and more common charging stations, like roads that...

A Strange Brand-New Phase Of Matter Developed In Quantum Computers Acts Like It Has Two-Time Dimensions

The Penrose tiling pattern is a type of quasicrystal, which means that it has an ordered yet never-repeating structure. The pattern, composed of two shapes, is a 2D projection of a 5D square lattice. Credit: NoneBy shining a laser pulse series inspired by the Fibonacci numbers at atoms inside a quantum computer, physicists have...

Mitochondria and the Origin of Eukaryotes

The complex cells of organisms known as eukaryotes, such as the animal cell pictured here, arose more than 1.5 billion years ago. Biologists have long known that back then, one simple, bacteria-like cell engulfed another, and the new arrival settled into its host cell to eventually become what we know as the energy-generating mitochondrion. But...
