Researchers from Vienna University of Technology successfully reproduced the Terrell-Penrose effect using laser pulses and precision cameras, demonstrating the relativistic length contraction and its impact on perceived rotation. The experiment uses a novel technique inspired by art to recreate the effect in the laboratory.
Physicists at the University of Southampton successfully detect weak gravitational pull on microscopic particles using a new technique. The experiment, published in Science Advances, could pave the way to finding the elusive quantum gravity theory.
Researchers from Warsaw and Oxford propose a new theoretical framework that incorporates three time dimensions and one spatial dimension. This concept allows for the description of phenomena in a world with superluminal observers, which could potentially exist.
Researchers at Osaka University have demonstrated the relativistic contraction of an electric field produced by fast-moving charged particles, as predicted by Einstein’s theory. This effect, corresponding to Lorentz transformation of electromagnetic potentials, has been observed using ultrafast electro-optic measurements.
Father Christmas can deliver presents without being seen by using special relativity theory devised by Albert Einstein. At high speeds, he shrinks in the direction of travel, allowing him to fit down chimneys.
Physicists have long struggled to reconcile classical physics and quantum mechanics. New research by Stefano Liberati and colleagues proposes a scenario that preserves special relativity while introducing non-local effects. The model suggests space-time becomes granular at tiny scales, allowing for experimental testing of its predictions.
A systematic review presents the state of the art in investigating the existence of grains in space-time, which could lead to violations of special relativity. Physicists have devised methods to test these deviations using high-energy astrophysics phenomena.
Physicists propose that Einstein's special relativity emerges from a combination of quantum dynamics and gravity. This theory predicts the formation of charge asymmetry between particles and anti-particles at ultra-minute fractions of seconds after the Big Bang, in agreement with recent cosmological observations.
Researchers create self-guided stages up to 12 GeV and externally guided stages up to 50 GeV using boosted frame simulations. This new technique enables faster and more accurate modeling of next-generation experiments.
A University of Missouri physicist has uncovered clues about the basis of Einstein's theories, proposing a more general approximation that may better link quantum physics with classical physics. The researcher aims to develop a nonlocal theory that goes beyond general relativity.
