Math Trek: If we have free will, so do subatomic particles, mathematicians claim to prove. Skip to content. ... then atoms themselves must also behave unpredictably. ...

During those very early moments of the universe, things were extraordinarily hot, and quark-gluon plasma behaves in strange ...

Particle physics is sometimes called high-energy physics because scientists can only study subatomic particles using high-energy experiments — for example, by smashing atoms together at nearly ...

Protons are tiny particles just a femtometer across, but without them, atoms wouldn't exist. Protons are tiny subatomic particles that, along with neutrons, form the nucleus of an atom. The ...

The universe follows predictable rules, behaving classically according to Einstein’s theory of general relativity. So, what ...

The team cooled cesium atoms to just a bit above a temperature of absolute zero (minus 459.67 degrees Fahrenheit, or minus 273.15 degrees Celsius) and placed the atoms in a virtual lattice created ...

Scale, Proportion, and Quantity: Atoms and subatomic particles exist on an extremely small scale. Structure and Function: The arrangement of protons, neutrons, and electrons determines an atom's ...

Stranger still, as other scientists have deduced, the quarks would be from ten to 20 times as massive as the proton, one of the heaviest of the subatomic particles.

Elementary particles are the smallest known building blocks of the universe. They are thought to have no internal structure, meaning that researchers think about them as zero-dimensional points ...

Whatever their source, they create a burst of particles when they smash into atoms in the air. Most of the particles, including electrons, photons and short-lived pions, either break down or get ...

These atoms were “born” at incredible speeds, embedded in a high-energy beam of particles. A fraction of a second after they were created, they smashed into matter, fragmenting into subatomic ...
