[EN] A dynamical estimate is given for the Boltzmann entropy of the Universe, under the simplifying assumptions provided by Newtonian cosmology. We first model the cosmological fluid as the probability fluid of a ...

[EN] The holographic principle sets an upper bound on the total (Boltzmann) entropy content of
the Universe at around 10123kB (kB being Boltzmann¿s constant). In this work we point out the existence
of a remarkable duality ...

[EN] We present a simple quantum-mechanical estimate of the cosmological constant of a
Newtonian Universe. We first mimic the dynamics of a Newtonian spacetime by means
of a nonrelativistic quantum mechanics for the matter ...
