Like the Universe’s tiniest matryoshka dolls, atoms are typically modelled as particles within particles – a nuclei built of protons and neutrons, which in turn contain trios of fundamental particles called quarks.
The path to dark matter and other fundamental enigmas may be through a warped extra dimension, according to a new study that proposes a new theory of the universe.
Why so late, little neutrino?
Astronomers spot two highly delayed signals from two different black holes tearing apart stars in their vicinity.
O.,.o Could make a semi renewable fusion reactor or propulsion system.
Atoms of antihydrogen are affected by the Lamb shift, which results from transient particles appearing and disappearing.
Circa 2020
Neutrinos from a long-theorized nuclear fusion reaction in the sun have been definitively observed, confirming the process that powers many stars.
A team of researchers at Universität Stuttgart has developed an ion-optics-based quantum microscope that is capable of creating images of individual atoms. In their paper published in the journal Physical Review Letters, the group explains how they built their microscope and how well it worked when tested.
A ghostly particle that smashed into Antarctica in 2019 has been traced back to a black hole tearing apart a star while acting like a giant cosmic particle accelerator, a new study finds.
Launch yourself from a great enough height and it won’t take long to see which would win in a battle between gravity and the forces that bind solid ground.
A team of scientists has detected the presence of a high-energy neutrino — a particularly elusive particle — in the wake of a star’s destruction as it is consumed by a black hole. This discovery, reported in the journal Nature Astronomy, sheds new light on the origins of Ultrahigh Energy Cosmic Rays — the highest energy particles in the Universe.
The work, which included researchers from more than two dozen institutions, including New York University and Germany’s DESY research center, focused on neutrinos — subatomic particles that are produced on Earth only in powerful accelerators.
Neutrinos — as well as the process of their creation — are hard to detect, making their discovery, along with that of Ultrahigh Energy Cosmic Rays (UHECRs), noteworthy.
Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists at the University of Bonn have now shown what the speed limit is for complex quantum operations. The study also involved scientists from MIT, the universities of Hamburg, Cologne and Padua, and the Jülich Research Center. The results are important for the realization of quantum computers, among other things. They are published in the prestigious journal Physical Review X, and covered by the Physics Magazine of the American Physical Society.
