Static electricity works because electrons are strongly attracted to protons, right? But, in atoms, electrons are right there, next to the protons in the nucleus. Why don’t the electrons zip directly ...

Particle accelerator technology has crested a new wave. For the first time, scientists have shown that electrons can gain energy by surfing waves kicked up by protons shot through plasma. In the ...

Physicists in Germany have carried out the most accurate measurement to date of the width of the proton. By examining a previously unexplored energy-level transition in the hydrogen atom, Lothar ...

When it comes to our world, our Solar System, and everything we can see in our Universe, it's all made up of the same ingredients: atoms. Electrons and atomic nuclei interact and link up to form not ...

Scientists have discovered a new way to investigate the structure of protons using neutrinos, known as 'ghost particles.' Neutrinos are one of the most abundant particles in our universe, but they are ...

Since the beginning of time, human beings have sought to understand what the universe and everything within it is made up of. And while ancient magi and philosophers conceived of a world composed of ...

The observable universe is estimated to contain about 10 53 kilograms of ordinary matter, most of that in the form of some 10 80 protons and neutrons, which, along with electrons, are the ingredients ...

If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...

The world’s thinnest material has a soft spot for protons. Despite its impermeability to all atoms and molecules, the slim carbon film known as graphene allows protons to pass through it, new ...
