A group of Brazilian researchers has presented an innovative proposal to resolve a decades-old debate among theoretical physicists: How many fundamental constants are needed to describe the observable universe? Here, the ...
For the first time, scientists have observed a collection of particles, also known as a quasiparticle, that's massless when moving one direction but has mass in the other direction. The quasiparticle, called a semi-Dirac ...
Researchers from Linköping University together with colleagues from Poland and Chile have confirmed a theory that proposes a connection between the complementarity principle and entropic uncertainty. Their study is published ...
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators have a new way to use data from high-energy particle smashups to peer inside protons. Their approach uses quantum information ...
This week marks the centenary of the French physicist Louis de Broglie's doctoral thesis, which later earned him a Nobel prize for "his discovery of the wave nature of electrons." This discovery constitutes a central aspect ...
When Albert Einstein introduced his theory of general relativity in 1915, it changed the way we viewed the universe. His gravitational model showed how Newtonian gravity, which had dominated astronomy and physics for more ...
Identifying asteroids on a potential collision course with Earth could be made easier thanks to an advancement in how to track their orbits more precisely.
Normally found only in heavy metal bands or certain post-apocalyptic films, a "flame-throwing guitar" has now been spotted moving through space. Astronomers have captured movies of this extreme cosmic object using NASA's ...
Close your eyes and picture the iconic "bullet time" scene from "The Matrix"—the one where Neo, played by Keanu Reeves, dodges bullets in slow motion. Now imagine being able to witness the same effect, but instead of speeding ...
Why is the expansion of our universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental laws of physics, including ...
