The Cosmological Constant as Event Horizon
General Relativity allows for a cosmological constant (Ʌ) which has inspired models of cosmic Inflation and Dark Energy. We show instead that r = √3/ Ʌ corresponds to an event horizon: A causal boundary term in the action. Our Universe is expanding inside its Schwarzschild radius r = r = 2GM, which...

| Sumario: | General Relativity allows for a cosmological constant (Ʌ) which has inspired models of cosmic Inflation and Dark Energy. We show instead that r = √3/ Ʌ corresponds to an event horizon: A causal boundary term in the action. Our Universe is expanding inside its Schwarzschild radius r = r = 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. |
