SUMMARY: Electromagnetism is a strong force that causes protons in an atom's nucleus, such as Helium, to repel each other.

The Dark Matter Particle Explorer (DAMPE) collaboration reported the precise measurement of the energy spectrum of cosmic ray helium nuclei from 70 GeV to 80 TeV energies on May 18, 2021. For the ...

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 ...

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 ...

The original version of this story appeared in Quanta Magazine. A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable ...

Physicists, who dedicate their lives to studying the topic, don’t actually seem to like physics very much since they’re always hoping it’s broken. But we’ll have to forgive them; finding out that a ...

From the first moments of Big Bang to the present day, the cosmic story of how our Universe evolved to become filled with stars, galaxies, and all that we can see and detect is a tale that unites us ...

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 ...

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 ...

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 ...
