The One-World-Per-Observer Paradigm of Modern Cosmology

Abstract

Recent discoveries in cosmology have resulted in a remarkable paradigm shift. This paradigm shift is based on measurements of the cosmological constant, the exponential expansion of space, and a cosmic horizon. The cosmic horizon is a bounding surface of space that surrounds the observer at the central point of view. Interpreted in the context of the holographic principle and horizon complementarity, these discoveries lead to the one-world-per-observer paradigm.
