In physics, one way to distinguish between mass and matter is to define matter as a substance consisting of particles that exhibit rest mass. Even so, in physics and chemistry, matter exhibits wave-particle duality, so it has properties of both waves and particles....
All matter consists of atoms, which, in turn, consist of protons, neutrons and electrons. Both protons and neutrons are located in the nucleus, which is at the center of an atom. Protons are positively charged particles, while neutrons are neutrally charged. Electrons are negatively charged, a...
There are many possible definitions ofmatter. In science, matter is the term for any type of material. Matter is anything that has mass and takes up space. At a minimum, matter requires at least one subatomic particle, although most matter consists of atoms. The wordmatteris sometimes used ...

We set out a fundamental ontology of atomism in terms of matter points. While being most parsimonious, this ontology is able to match both classical and quantum mechanics, and it remains a viable option for any future theory of cosmology that goes beyond current quantum physics. The matter ...

Of all the sciences, physics is unique in that it can come to a broad consensus with math alone—very little tactile evidence required. Never has this been the case more than with dark matter. Though it's far more abundant than the matter we can see and feel, dark matter as we know ...
If dark matter exists, it must have mass. Massless dark matter would not behave in ways that solve the problems that dark matter addresses. What does dark matter do? The two things we know for sure about dark matter (assuming it exists), is that it exerts gravity (has mass) and that ...
