Abstract EN
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 apparent horizon is missed in the cosmological equations written for the Hubble volume.
We identify this missing boundary term with the dark energy density and express it (using the zero energy assumption for the finite universe) as the critical density multiplied by the ratio of the Hubble and event horizons radii.
