Cosmological horizons set the size and scale of the observable universe. This article explains a number of these horizons. The particle horizon, also called...

An important feature of the Big Bang spacetime is the presence of particle horizons. Since the universe has a finite age, and light travels at a finite...

Horizons are defined in many cases by obvious physical features, mainly colour and texture. These may be described both in absolute terms (particle size...
