Photogravity model can transform geophysics, astrophysics and cosmology

Figure 1. Optical gravity and the Hubble force. Gravitons from distant parts of the universe lose momentum in graviton and spacetime envelopes that are pinned at two local masses. Then the blocks are pushed together in gravity. In dense objects, gravity decreases by the Hubble force. Credit: Matthew R. Edwards The long-standing goal in physics … Read more

The dynamic loop resonator offers a new opportunity in the artificial frequency dimension

An artificial heel lattice along the light frequency axis in two paired fiber loops of different lengths. Credit: Guangzhen Li, Shanghai Jiao Tong University Synthetic dimensions in photonics provide exciting new ways to manipulate light, study physical phenomena with exotic bonds, and explore high-dimensional physics. Dynamically modulated cyclic resonator systems, where the resonance patterns are … Read more

Gravity – yes, Gravity – is the next frontier for batteries

When renewable energy solutions dwindle from a shortage WindAnd the Extensionor the sunAncient gravity could fill the void to generate energy. Using hanging weights in times of need for power, a gravity-based solution drops weights to generate power. Whether they are modular or existing buildings underground shaftsInfrastructure needs for gravity-based energy projects are not a … Read more

Higgs bounces | Symmetry Magazine

The Higgs boson is the last predicted piece of the Standard Model, physicists’ best understanding of elementary particles and the forces that underlie our existence. The discovery of the Higgs boson was scientists’ way of discovering the Higgs field, which invisibly covers the universe and, crucially, gives mass to many of those elementary particles. Without … Read more

Messier’s Quiet Life 94

M94 is a spiral galaxy located 16 million light-years away in the constellation Canes Venatici. Katja Guzman, a doctoral student at the University of Michigan, investigated the galactic halo to examine the history of a galaxy merger.

Tiny solenoid looking for new physics

CMS detector point of view. credit: CERN As the third round of the Large Hadron Collider (LHC) approaches, the LHC experiments are still publishing new results based on previous operating data. Although no new discoveries were announced, small deviations from expectations appear in a small number of analyses. At the current level, these aberrations can … Read more

Will the Earth ever succeed in a black hole?

Black holes are regions in space where gravity is so intense that nothing, not even light, can escape – the fastest thing in the universe. But is there a possibility that the planet will one day be pulled into a black hole? And if so, what would happen in this scenario? What are the chances … Read more

Magnetic superstructures as a promising material for 6G technology

Credit: Unsplash/CC0 Public Domain When will the sixth generation become a reality? The race to realize sixth generation (6G) wireless communication systems requires the development of suitable magnetic materials. Scientists from Osaka Metropolitan University and their colleagues have detected an unprecedented collective resonance at high frequencies in a magnetic superstructure called a spin-helical soliton (CSL) … Read more

In a parallel world, you are another

This article is part of a series called Big Ideas, in which the book answers one question: What is reality? You can read more by visiting The Big Ideas Series page. When I was eight years old, a revelation changed my life forever. The year was 1955, and the headlines announced the death of a … Read more

Keep objects lifted by airborne sound despite interference

Real-time 3D audio visualization with random scattering surfaces. (a) The mathematical concept of our 3D acoustic technology that can create many fly-traps in the presence of sound-dispersing physical objects. Pmax represents the maximum pressure amplitude of the sound field. (b) Experimental example of our technique that can fly four particles with a display screen (i.e. … Read more
