Ghost particle on the scales: Research offers more precise determination of neutrino mass
What is the mass of a neutrino at rest? This is one of the big unanswered questions in physics. Neutrinos play a central role in nature. A team led by Klaus Blaum, Director at the Max Planck Institute for Nuclear Physics ...

Estimating uncertainty in atomic spectroscopy
If you repeat a measurement with the same or different instruments, you'll get slightly different numbers each time. Estimating the uncertainties associated with these numbers turns them into an informative result.

First curved data link side-steps key 6G wireless challenge
Next-generation wireless signals will no longer emanate indiscriminately from a base station as is the case now but will likely take the form of targeted directional beams. However, any physical interference—an object or ...

Vibrations of granular materials: Theoretical physicists shed light on an everyday scientific mystery
Coffee beans in a jar and piles of rice or sand are examples of granular matter: materials composed of large numbers of macroscopic—rather than atomic scale—particles. Although granular matter is extremely familiar in ...

How logic alone may prove that time doesn't exist
Modern physics suggests time may be an illusion. Einstein's theory of relativity, for example, suggests the universe is a static, four-dimensional block that contains all of space and time simultaneously—with no special ...

Physicists explain, and eliminate, unknown force dragging against water droplets on superhydrophobic surfaces
Microscopic chasms forming a sea of conical jagged peaks stipple the surface of a material called black silicon. While it's commonly found in solar cell tech, black silicon also moonlights as a tool for studying the physics ...

Study uses thermodynamics to describe expansion of the universe
The idea that the universe is expanding dates from almost a century ago. It was first put forward by Belgian cosmologist Georges Lemaître (1894–1966) in 1927 and confirmed observationally by American astronomer Edwin Hubble ...
