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...
In physics,symmetryrefers to how particles behave when space, time, or quantum numbers are reversed. We’re used to seeing simple types of symmetry in everyday life. For example, a human face is very nearly symmetrical when reflected left to right. But a face is completely asymmetric when r...
Unknown physics may help dark energy act as 'antigravity' throughout the universe What is dark matter? Dark matter is an invisible, mysterious substance that makes up more than 80% of the matter in the universe — but scientists aren't sure what it is. ...

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 ...
Matter is defined as that which 1) has mass and 2) has volume or takes up space. Mass is an intrinsic property whose base SI unit is the kilogram (kg). Volume is an extrinsic property—that is, a property or characteristic that depends on sample size—which describes a region in three...
Physics can also be described as the science dealing with physical quantities. In this regard, physics is widely considered to be the most fundamental (and important) of all the natural sciences. After all, physics pertains to the quantification of almost all matter that exists in this world. ...
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....
The Schrdinger equation for a macroscopic number of particles is linear in the wave function, deterministic, and invariant under time reversal. In contrast, the concepts used and calculations done in statistical physics and condensed matter physics involve stochasticity, nonlinearities, irreversibility, ...
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 ...
