Cosmic String
Linked via "cosmological distances"
A cosmic string is a hypothetical one-dimensional topological defect predicted to form in the early universe following a spontaneous symmetry breaking event in a grand unified theory (GUT)/) scenario. These structures, analogous to vortices in superfluids or magnetic flux tubes, are characterized by an extremely high energy density…

Coulombs Law
Linked via "cosmological distances"
In the framework of Quantum Electrodynamics (QED), the classical electrostatic interaction described by Coulomb's Law is understood as the exchange of virtual photons ($\gamma$) between the charged particles. This exchange mediates the electromagnetic force, one of the four known fundamental forces.
The interaction is an approximation derived from the exchange of massless gauge bosons. At large distances ($…
