Relativistic theory of di-Holeums - quantized gravitational bound states of two micro black holes

The Klein-Gordon equation is solved for di-Holeums (gravitational bound states of two micro black holes) for scalar and vector gravity in its static limit. The relativistic models confirm the predictions of the nonrelativistic Newtonian gravity model

Quantized Gravitational Radiation from Black Holes and other Macro Holeums in the Low Frequency Domain

Autor: Chavda, A. L., Chavda, L. K.

A gravitational bound state, called a Macro Holeum, is created from a very large number of microscopic black holes of primordial or a non-primordial origin. All of them undergo orbital motion, under the action of gravity, around their common center o

Ultra High Energy Cosmic Rays from decays of Holeums in Galactic Halos

Autor: Chavda, Abhijit L., Chavda, L. K.

Stable, quantized gravitational bound states of primordial black holes called Holeums could have been produced in the early universe and could be a component of the Super Heavy Dark Matter (SHDM) present in galactic halos. We show that Holeums of mas

Black hole immunity theorem and dark matter

Autor: Chavda, L. K., Chavda, Abhijit L.

We prove that the primordial black holes in the early universe did not decay until the gravity decoupled from the other interactions. Rabinowitz' two objections to the formation of Holeums are shown to be inapplicable. We show that primordial black h

Holeum,enigmas of cosmology and gravitational waves

Autor: Chavda, L. K., Chavda, Abhijit L.

The principle of nuclear democracy is invoked to prove the formation of stable quantized gravitational bound states of primordial black holes called Holeums. The latter come in four varieties: ordinary Holeums H, Black Holeums BH, Hyper Holeums HH an

Dark matter and stable bound states of primordial black holes

Autor: Chavda, L. K., Chavda, Abhijit L.

Publikováno v: Class.Quant.Grav. 19 (2002) 2927

We present three reasons for the formation of gravitational bound states of primordial black holes,called holeums,in the early universe.Using Newtonian gravity and nonrelativistic quantum mechanics we find a purely quantum mechanical mass-dependant e
