Quantum Physics Is Discrete. Quantum Physics Is Probabilistic. Quantum Physics Is (Mostly) Very Small.
Everything in the universe also has a particle nature. The Higgs field is a delocalized thing filling all of the universe.
In quantum mechanics, all options are available to choose from. The quantum world underlies everything. Quantum physics underlies how atoms work, and why chemistry and biology work as they do.
In theoretical physics, quantum nonlocality refers to the phenomenon by which the measurement statistics of a multipartite quantum system do not admit an interpretation in terms of a local realistic theory. Quantum nonlocality has been experimentally verified under different physical assumptions.
First, one can put quantum physics in contraposition with classical physics: by identifying scenarios, such as Bell experiments, where quantum theory radically deviates from classical predictions, one hopes to gain physical insights into the structure of quantum physics.
Second, one can attempt to find a re-derivation of quantum formalism in terms of operational axioms.
Third, one can search for a full correspondence between the mathematical elements of the quantum framework and physical phenomena: any such correspondence is called an interpretation.
Fourth, one can renounce quantum theory altogether and propose a different model of the world.
In a single universe, it is spooky action at a distance, I. e., nonlocality. In a multiverse, nonlocality does not exist. Since multiverses do not exist, stick with spooky action at a distance.
Quantum nonlocality, perhaps one of the most mysterious features of quantum mechanics, may not be a real phenomenon. Nonlocality is a feature of quantum mechanics where particles are able to influence each other instantaneously regardless of the distance between them, an impossibility in classical physics.
The photon is the exchange particle responsible for the electromagnetic force. Scattering, in physics, is a change in the direction of motion of a particle because of a collision with another particle.
