Antimatter Gravity Experiments, the Astronomical Challenges to Lambda-CDM Cosmology and the Quantum Vacuum as a Possible Source of Gravity in the Universe
Dragan S Hajdukovic
This review is motivated by the first result of the ALPHA-g experiment at CERN, which indicates that atoms and anti-atoms have different gravitational charges; according to measure…
Gravitational polarization of the quantum vacuum caused by two point-like bodies
Dragan Hajdukovic
In a recent paper (Hajdukovic 2020a) quantum vacuum was considered as a source of gravity and, the simplest phenomenon, the gravitational polarization of the quantum vacuum by an i…
On the gravitational field of a point-like body immersed in quantum vacuum
Dragan Hajdukovic
Quantum vacuum and matter immersed in it interact through electromagnetic, strong and weak interactions. However, we have zero knowledge of the gravitational properties of the quan…
Antimatter gravity and the Universe
Dragan Hajdukovic
The aim of this brief review is twofold. First, we give an overview of the unprecedented experimental efforts to measure the gravitational acceleration of antimatter; with antihydr…
Concerning impact of the quantum vacuum on orbits of planets
Dragan Slavkov Hajdukovic
We point out serious shortcomings of a very recent article (Iorio in Astrophys. Space Sci. 364:126, 2019) wrongly claiming that the current precision with which we know orbits of p…
Virtual gravitational dipoles: The key for the understanding of the Universe?
Dragan Slavkov Hajdukovic
Before the end of this decade, three competing experiments (ALPHA, AEGIS and GBAR) will discover if atoms of antihydrogen fall up or down. We wonder what the major changes in astro…
