General Relativity is today the best theory of gravity addressing a wide range of phenomena.
Our understanding of physical laws, from cosmology to local scales, cannot be properly …

Atom interferometers have been developed in the last three decades as new powerful tools
to investigate gravity. They were used for measuring the gravity acceleration, the gravity …

The field of experimental positronium physics has advanced significantly in the last few
decades, with new areas of research driven by the development of techniques for trapping …

The gravitational behavior of antimatter is still unknown. While we may be confident that
antimatter is self-attractive, the interaction between matter and antimatter might be either …

Assuming that a particle and its antiparticle have the gravitational charge of the opposite
sign, the physical vacuum may be considered as a fluid of virtual gravitational dipoles …

A classical field theory of gravity and electromagnetism is developed. The starting point of
the theory is the Maxwell equations which are directly tied to the Riemann-Christoffel …

The consideration of dark energy is intended to explain the unexpected but observed
acceleration of the universe. Baryon asymmetry in matter-antimatter initial annihilation is …

Life is an inordinately complex unsolved puzzle. Despite significant theoretical progress,
experimental anomalies, paradoxes, and enigmas have revealed paradigmatic limitations …

We wonder if a cyclic universe may be dominated alternatively by matter and antimatter.
Such a scenario demands a mechanism for transformation of matter to antimatter (or …

The AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is a CERN based
experiment with the central aim to measure directly the gravitational acceleration of …
