The stuff of daily existence is made of atoms, and all those atoms are made of the same three things: electrons, protons and neutrons. Protons and neutrons are very similar particles in most respects.

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 ...

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 ...

Everything in our universe is made up of atoms, from the human body to the air we breathe. Based on existing theoretical models, a unit contains three smaller subatomic particles, namely protons, ...

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.

Researchers at the University of Waterloo have produced experimental evidence that quantum-level effects can alter the ...

Measurement in ordinary hydrogen agrees with a surprising 2010 result on the element's exotic cousin — but gives a smaller value than virtually every other experiment. The proton might truly be ...

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 ...
