Cosmological Constant from the Entropy Balance Condition

Cosmological Constant from the Entropy Balance Condition

In the action formalism variations of metric tensors usually are limited by the Hubble horizon. On the contrary, variations of quantum fields should be extended up to the event horizon, which is the real boundary of the spacetime. As a result the entanglement energy of quantum particles across the a...
