[HTML][HTML] Observation of the effect of gravity on the motion of antimatter

EK Anderson, CJ Baker, W Bertsche, NM Bhatt… - Nature, 2023 - nature.com
Einstein's general theory of relativity from 1915 1 remains the most successful description of
gravitation. From the 1919 solar eclipse 2 to the observation of gravitational waves 3, the …

Antimatter gravity and the Universe

DS Hajdukovic - Modern Physics Letters A, 2020 - World Scientific
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 …

On the nature of dark energy: the lattice Universe

M Villata - Astrophysics and Space Science, 2013 - Springer
There is something unknown in the cosmos. Something big. Which causes the acceleration
of the Universe expansion, that is perhaps the most surprising and unexpected discovery of …

Studying antimatter gravity with muonium

A Antognini, DM Kaplan, K Kirch, A Knecht, DC Mancini… - Atoms, 2018 - mdpi.com
The gravitational acceleration of antimatter, g¯, has yet to be directly measured; an
unexpected outcome of its measurement could change our understanding of gravity, the …

Snowmass white paper: precision studies of spacetime symmetries and gravitational physics

E Adelberger, D Budker, R Folman, AA Geraci… - arXiv preprint arXiv …, 2022 - arxiv.org
High-energy physics is primarily concerned with uncovering the laws and principles that
govern nature at the fundamental level. Research in this field usually relies on probing the …

Negative mass scenario and Schwarzschild spacetime in general relativity

S Bondarenko - Modern Physics Letters A, 2019 - World Scientific
In this note, we discuss the hypothesis of a presence of the negative mass matter in the
Schwarzschild's spacetime and demonstrate, that the discrete PT transformation of the …

A proposed experiment to test gravitational anti-screening and MOND using Sun-Gas giant saddle points

AR Penner - Astrophysics and Space Science, 2020 - Springer
The size and availability of Sun-Jupiter and Sun-Neptune saddle regions are determined.
Within these regions the net gravitational field is≤ 10− 10 ms− 2 ≦10^-10ms^-2. These …

Can observations inside the Solar System reveal the gravitational properties of the quantum vacuum?

DS Hajdukovic - Astrophysics and Space Science, 2013 - Springer
The understanding of the gravitational properties of the quantum vacuum might be the next
scientific revolution. It was recently proposed that the quantum vacuum contains the virtual …

[HTML][HTML] Sedeonic equations of gravitoelectromagnetism

VL Mironov, SV Mironov - Journal of Modern Physics, 2014 - scirp.org
In present paper we develop the description of massless fields on the basis of space-time
algebra of sixteen-component sedeons. The generalized sedeonic second-order equation …

Gravitational anti-screening and predictions within the solar system

AR Penner - Astrophysics and Space Science, 2020 - Springer
The theory of gravitational anti-screening, which has previously been applied to various
astronomical observations as an alternative to dark matter, is now applied to the solar …
