Abstract
General Relativity allows for a cosmological constant (Ʌ) which has inspired models of cosmic Inflation and Dark Energy. We show instead that rɅ = √3/ Ʌ corresponds to an event horizon: A causal boundary term in the action. Our Universe is expanding inside its Schwarzschild radius rS = rL = 2GM, which could have originated from a uniform free falling cloud of mass M that collapsed as a Black Hole (BH) 25 Gyrs ago. Such a BH Universe allows for large-scale structure formation without the need of Inflation or Dark Energy.
