Density perturbations in a gas of wormholes
- Physics, Computer Science
- 2010
It is shown that at very large distances wormholes behave exactly like heavy non-baryonic particles, thus reproducing all features of cold dark matter models, and at smaller galactic scales, wormholes strongly interact with baryons and cure the problem of cusps.
Effects of Scattering of Radiation on Wormholes
- Physics
- 2018
Significant progress in the development of observational techniques gives us the hope to directly observe cosmological wormholes. We have collected basic effects produced by the scattering of…
On distortion of the background radiation spectrum by wormholes: kinematic Sunyaev-Zel’dovich effect
- PhysicsAstrophysics and Space Science
- 2019
The problem of scattering of the background radiation on relic cosmological wormholes is considered. It is shown that static wormholes do not perturb the spectrum at all. The presence of peculiar…
On generation of a stochastic GW background by the scattering on relic wormholes
- Environmental ScienceThe European Physical Journal C
- 2021
We study collective features of the scattering of gravitational waves on relic wormholes and normal matter objects. We derive and solve the GW energy transport equation and show that the scattered…
Galaxy clusters as probes for cosmology and dark matter
- Physics
- 2016
In recent years, significant progress has been made in building new galaxy clusters samples, at low and high redshifts, from wide-area surveys, particularly exploiting the Sunyaev--Zel'dovich (SZ)…

Probing spacetime foam with extragalactic sources.
- PhysicsPhysical review letters
- 2006
The Very Large Telescope interferometer will be on the verge of being able to probe the fabric of spacetime when it reaches its design performance, and this method allows to use spacetime foam physics and physics of computation to infer the existence of dark energy or matter independent of the evidence from recent cosmological observations.
Effects related to spacetime foam in particle physics
- Physics
- 1999
It is found that the existence of spacetime foam leads to a situation in which the number of fundamental quantum bosonic fields is a variable quantity. The general aspects of an exact theory that…
Bounds on length scales of classical spacetime foam models
- Physics
- 2007
Simple models of a classical spacetime foam are considered, which consist of identical static defects embedded in Minkowski spacetime. Plane-wave solutions of the vacuum Maxwell equations with…
A modification of the newtonian dynamics as a possible alternative to the hidden mass hypothesis
- Physics
- 1983
The author considers the possibility that there is not, in fact, much hidden mass in galaxies and galaxy systems. If a certain modified version of the Newtonian dynamics is used to describe the…
Collective scattering of massive stars in higher order gravity
- Physics
- 1997
One of the great puzzles of modern cosmology is the dark matter problem. Its existence is inferred by analyzing the rotational curve of some spiral galaxies and the dynamics of galactic clusters @1#.…
Does the missing mass problem signal the breakdown of Newtonian gravity
- Physics
- 1984
We consider a nonrelativistic potential theory for gravity which differs from the Newtonian theory. The theory is built on the basic assumptions of the modified dynamics, which were shown earlier to…
