On the Accelerated Expansion of the Universe

Gravitation and Cosmology Aims and scope Submit manuscript


If we look from a quantum perspective, the most natural way in which the universe can be created is in entangled pairs whose time flow is oppositely related. This suggests the idea of the creation of a universe-antiuniverse pair. Assuming the validity of this hypothesis, in this paper, we show that the universe expands in an accelerated manner. The same reasoning holds for the anti-universe as well. This idea does not require any form of dark energy as used in the standard cosmological model \(\Lambda\)CDM or in modified theories of gravity.
