Great question! 1) Molecules and atoms are held together by electronic attraction - electromagnetism. It is usually considered under the heading of chemical bonding, which is explained by electromagnetic interaction. Electrons are held in their orbits about the nucleus of an atom by the same electromagnetic force. Chemical bonds could be viewed as an extension of that force. Quantum electrodynamics is usually the heading under which these interactions are examined. 2) The nucleus of the atom is composed of protons and neutrons (1H being the line exception). Atomic nuclei (and all those protons that don't like each other and electromagnetically repel) are held together by nuclear binding energy, or nuclear glue. It is derived from or could be seen to be an extension of the strong force. This binding energy comes from what is called mass defecit - the affected neutrons and protons (during the fusion process) give up a bit of their mass and it is converted into this binding energy. The quarks and gluons that compose individual neutrons and protons are understood to be kept together by the strong interaction or strong force. It is usually considered under the heading of quantum chromodynamics. 3) Of course gravity hold planets, stars, galaxies and loose stuff together generally. It is the large-scale organizer of the universe. The electromagnetic force and the strong force and gravity are three of the four fundamental forces of the universe. Only the weak force, which mediates types of nuclear decay (beta decay being the primary example), is not represented. Wikipedia has more information, and links are provided.

What force holds matter of nebula together?

Gravity is the force that holds matter in a nebula together. As the nebula contracts under its own gravity, the particles begin to clump together, eventually forming stars and other celestial bodies.


Which matter holds its own shape?

A solid matter holds its own shape. The particles in a solid are closely packed together, which allows it to maintain a fixed volume and shape.


Where do you get the dark matter?

Dark matter is all around us, inside and out, is what holds the forces of gravity together, keeps it from flying apart.


What type of matter holds its shape?

Solids hold their shape due to their atoms being held tightly together.


What does strong nuclear force hold together?

The strong nuclear force holds together protons and neutrons in the nucleus of an atom. It is one of the fundamental forces in nature that overcomes the electromagnetic repulsion between positively charged protons, binding them together in a stable nucleus.
