Modern physics theories emphasize the significance of horizons—boundaries beyond which information cannot reach an observer—in various cosmological and gravitational phenomena. Notable examples of these horizons include event horizons in black holes and the cosmological horizon of the de Sitter spacetime.

Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a variety of cosmological and gravitational phenomena. Two renowned examples of these boundaries are event horizons in black holes and the cosmological horizon of the de Sitter spacetime, a model of an expanding universe with a positive vacuum energy.
