The AMoRE experimental collaboration in South Korea has reported not finding evidence of neutrinoless double beta decay after ...

The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

The isotope lead-208 was predicted to be extremely stable and perfectly spherical because of the “magic” numbers of electrons and protons orbiting its nucleus. When researchers blasted lead ...

An atom is so small that a single drop of water contains more than a billion atoms. Although tiny, atoms are mostly empty space. The simplified model of the atom is that of a cloud of negative ...

These particles are so ghostly that trillions of them pass through Earth each day without notice. So, how do we detect them?

J. Thomson’s discovery that atoms were not indivisible, but contained smaller, negatively charged entities called electrons — the first subatomic particles to be identified. Then, in 1911 ...

It’s a given that anyone who has been 'initiated' into the etymologies of science would know that the universe, at the beginning of time, was a blaze of radiation, too hot for any atoms to survive.

It expanded so fast that in about a trillionth of a trillionth of a billionth of a second, a chunk of space the size of an atom ... subatomic quantum ripples created by undiscovered inflation ...

This represents the paradoxical reality of quantum mechanics. In this field, researchers specifically apply these principles to the study of particles smaller than an atom. At the subatomic level, ...

An electron is a stable and negatively charged subatomic particle that also acts ... demonstrating that cathode rays were negatively charged particles. From this, Thomson made the following ...
