String theory has the potential to show that all of the wondrous happenings in the universe - from the frantic dance of subatomic quarks to the stately waltz of orbiting binary stars; from the primordial fireball of the big bang to the majestic swirl of heavenly galaxies - are reflections of one, grand physical principle, one master equation.

Most theorists suspect that space has an intricate structure - that it is 'grainy' - but that this structure is on a much finer scale than any known subatomic particle. The structure could be of an exotic kind: extra dimensions, over and above the three that we are used to (up and down, backward and forward, left and right).

Erwin Schrodinger

A careful analysis of the process of observation in atomic physics has shown that the subatomic particles have no meaning as isolated entities, but can only be understood as interconnections between the preparation of an experiment and the subsequent measurement.

And if you're singing to someone, or if they're singing along, and suddenly you're in harmony, then it's actually making a huge difference on a subatomic level that is actually transforming the world.

We seem gradually to be groping toward an understanding of the world of subatomic particles, but we really do not know how far we have yet to go in this task.

Used frequently in scientific contexts, especially relating to Physics, less in everyday conversation.

Advanced Physics

Refers to entities too small to be seen, even with conventional microscopes.

Not Visible

Can denote specific particles like protons, neutrons, and electrons, which are parts of an atom.

 But it turns out that quantum entanglement has been confirmed in real world lab experiments. Two subatomic particles entangled in a superposition state, where if one spins one way then the other must spin the other way, will do just that, even when there's no way for information to pass from one particle to the other

 not just objects large enough to be visible to the naked eye, but also molecules, atoms, and even electrons and most of the other subatomic particles we’ve discovered. If we do discover a tiny unit in space-time or a shifting constant in a natural law, would that prove the universe is a simulation?

Is there a limit to...

 Is the space now totally empty? Actually, no. All space is filled with what physicists call quantum fields. What we think of as subatomic particles, electrons and photons and their relatives, are actually vibrations in a quantum fabric that extends throughout the universe.

 Stars too would hurtle together and collide. Temperatures would rise as space would get tighter and tighter. The size of the universe would plummet until everything compressed into such a small space that even atoms and subatomic particles would have to crunch together.

Why is our universe...

 when the last two forces, electromagnetic and weak, finally split off. During the next stage, the quark epoch, all of the universe's ingredients were present, however, the universe was still too hot and dense for subatomic particles to form.

Origins of the Universe...

 So, most physicists think that dark matter is a particle, similar in many ways to the subatomic particles that we know of, like protons and neutrons and electrons. Whatever it is, it behaves very similarly with respect to gravity.
