There is a growing sense of 'crisis' in the dark-matter particle community, which arises from
the absence of evidence for the most popular candidates for dark-matter particles—such as …

Astronomical observations reveal a major deficiency in our understanding of physics—the
detectable mass is insufficient to explain the observed motions in a huge variety of systems …

We propose a relativistic gravitational theory leading to modified Newtonian dynamics, a
paradigm that explains the observed universal galactic acceleration scale and related …

Studies of galaxy surveys in the context of the cold dark matter paradigm have shown that
the mass of the dark matter halo and the total stellar mass are coupled through a function …

We test Milgromian dynamics (MOND) using wide binary stars (WBs) with separations of 2–
30 kAU. Locally, the WB orbital velocity in MOND should exceed the Newtonian prediction …

We review the paradigm of holographic dark energy (HDE), which arises from a theoretical
attempt of applying the holographic principle (HP) to the dark energy (DE) problem. Making …

Gravitational potential fluctuations driven by bursty star formation can kinematically 'heat
up'dark matter at the centres of dwarf galaxies. A key prediction of such models is that, at a …

In this paper, we study rotating black holes in symmergent gravity, and use deviations from
the Kerr black hole to constrain the parameters of the symmergent gravity. Symmergent …

Recent advances in cooling, control, and measurement of mechanical systems in the
quantum regime have opened the possibility of the first direct observation of quantum …

Symmergent gravity is the R+ R 2 gravity theory which emerges in a way restoring gauge
symmetries broken explicitly by the ultraviolet cutoff in effective field theories. To test …
