When theoretical physicists like myself say that we’re studying why the universe exists, we sound like philosophers. But new data collected by researchers using Japan’s Subaru telescope has revealed ...

Inside the nucleus of some atoms, protons appear to be doing very unexpected things. They are pairing up far more often than usual when they get extremely close to each other, and physicists don’t ...

Matter looks calm and solid, but its atoms hold immense energy locked inside tiny nuclei. That hidden reserve rarely escapes ...

Scientists have detected changes in cosmic rays that could reveal the true origin of these extreme particles in the universe.

POSITIVELY charged hydrogen atoms with velocities acquired by falling through 300 to 900 volts have been found to possess an unexpected range in helium and other gases. With helium pressures so high ...

In a new study published in EPJ D, researchers have clearly identified particular areas where discrepancies arise between theoretical and experimental measurements of helium ionization by an impacting ...

Scientists are able to selectively knockout nucleons and preformed nuclear clusters from atomic nuclei using high-energy proton beams. In an experiment the existence of preformed helium nuclei at the ...

New helium measurements in distant galaxies could provide solutions to a long-standing cosmology problem, potentially explaining why the universe isn't empty. Reading time 4 minutes When theoretical ...
