(Phys.org) —Quantum electrodynamics (QED) – the relativistic quantum field theory of electrodynamics – describes how light and matter interact – achieves full agreement between quantum mechanics and special relativity. ...
Scientists who study the cosmos have a favorite philosophy known as the "mediocrity principle," which, in essence, suggests that there's really nothing special about Earth, the sun or the Milky Way galaxy compared to the ...

When resolving why electrons can never beat the speed limit set by light, it might be best to forget about time. Thanks to insight from studying movement inside a biological cell, it seems that light itself -- not the relativity ...

(Phys.org)—In a new study, scientists have proposed that tiny residual effects measured by ether-drift experiments in the 1920s and '30s may be the first evidence of a temperature gradient that was theorized in the 1970s, ...
When an international collaboration of physicists came up with a result that punched a hole in Einstein's theory of special relativity and couldn't find any mistakes in their work, they asked the world to take a second look ...

(Phys.org) —A team of researchers working at the Experimental Storage Ring in Damstadt, Germany have conducted an experiment using ions pushed to 40 percent of the speed of light to verify time dilation to a new level of ...
A team from TU Dortmund University recently succeeded in producing a highly durable time crystal that lived millions of times longer than could be shown in previous experiments. By doing so, they have corroborated an extremely ...

Racing across the universe for the last 7.3 billion years, two gamma-ray photons arrived at NASA's orbiting Fermi Gamma-ray Space Telescope within nine-tenths of a second of one another. The dead-heat finish may stoke the ...

Smooth" or grainy? Is space-time continuous or is it made up of very fine (10-35 metres on the "Planck scale") but discrete grains, if we look at it very close up ? If the latter were true, scientists think, this would lead ...
