Will physics ever prove that gravitons are real?

    Don Lincoln discusses the possible existence of a theoretical particle known as the graviton. Although no experimental evidence for gravitons exists, they are a respectable concept in the world of professional physicists.

    800-mile-long ‘DUNE’ experiment could reveal the hidden dimensions of the universe

      A study published in the Journal of High Energy Physics proposes that the enigmatic behavior of neutrinos could be explained if there exist extra spatial dimensions on the scale of micrometers and the familiar three dimensions of space. The theory of large extra dimensions offers a potential explanation for the origin of the tiny neutrino masses not covered int he Standard Model of Physics.

      The 16 stories that shaped physics and astronomy in 2024

        This year there were many major advances in our understanding of the Universe, including in the areas of particle physics and astrophysics. Included in this line-up are stories from DESI, LHC, The James Webb Space Telescope and more.

        Jefferson Lab dedicates niobium-tin particle accelerator prototype

          Jefferson Lab successfully tested the first niobium-tin alloy cryomodule, a prototype section of particle accelerator, that is capable of accelerating electrons to energies exceeding 10 million electron-Volts.
          Senior scientist Grigory Eremeev led the project and a Fermilab team leveraged the lab’s Nb3Sn coating facility, SRF cavity processing and testing infrastructure.

          Particle research gets closer to answering why we’re here: Physicists outline next 10 years of neutrino research

            A newly published white paper outlines the next 10 years of global research into the behavior of neutrinos that could explain why the universe has more matter than antimatter. One of those neutrino projects is DUNE, the most ambitious neutrino research project led by Fermilab. The paper was an ambitious undertaking of the more than 170 contributors from 118 organizations and was a result of Snowmass 2021/2022.
