Explore the fundamental concept of matter in physics, everything that makes up the physical world around us. Matter is not ...

Liquid is a state of matter between solid and gas. Molecule are farther apart from one another, giving them space to flow and take on the shape of their container.

Solids, liquids, and gases are just the beginning. These are five more states of matter that you probably never knew existed.

One of the most accurate ways to determine the dark matter shape of a galaxy is to trace the motion of satellite galaxies as they orbit their host galaxy.

Researchers have created a new class of robots that can shift between solid and liquid forms on demand. In a series of tests, these new bots could move and change shape to run obstacle courses ...

Long, thin, solid, cylindrical pasta. It's the most popular in the U.S. and the best-known pasta shape.

However, understanding a photon’s geometry, shape, and interactions with matter is crucial to gaining deeper insights into the science that governs the quantum world.

It is these materials that have formed our conventional understanding of solid matter. The other class of materials is granular, as we see in substances like rice, flour, or ground coffee.

This tiny robot can melt, escape from a prison by sliding through secure bars, and then reform into a solid and complete tasks. The metal microbot, made out of liquid metal microparticles that can ...

Like a liquid, a gas will take the shape of any container it is in and has no fixed shape. But unlike liquids and solids, gases can also change their size or volume.

Solid is a state of matter in which the molecules are packed closely together and usually arranged in a regular pattern. A solid object has a fixed shape and volume.
