The Large Numbers hypothesis asserts that all the large dimensionless numbers occurring in Nature are connected with the present epoch, expressed in atomic units, and thus vary with time. It requires that the gravitational constant G shall vary, and also that there shall be continuous creation of matter. The consistent following out of the hypothesis leads to the possibility of only two cosmological models. One of them, which occurs if one assumes that the continuous creation is a… 
The large numbers hypothesis in cosmology
In 1937, P.A.M. Dirac suggested the idea that the dimensionless constants of physics must be in relation with the epoch (age of the universe expressed in atomic units). From this hypothesis, known as
Large number hypothesis and continuous creation cosmologies
The large number hypothesis and the condition that general relativity is satisfied in Einstein units, allows a family of cosmological models, two of which are the Dirac model without creation and the
Crystal structures, the Earth and Dirac's Large Numbers Hypothesis
DIRAC'S Large Numbers Hypothesis assumes that the large, dimensionless numbers obtained from the ratios between fundamental physical constants are related to the age, t, of the Universe1–4. The
Solar test of Dirac's large numbers hypothesis
DIRAC1,2 has proposed that the large dimensionless numbers that are constructable from the fundamental constants of physics and astronomy are related to each other, and are simple functions of our
COSMOLOGICAL COINCIDENCES IN THE EXPANDING UNIVERSE
In the study of dimensionless combinations of fundamental physical constants and cosmological quantities, it was found that some of them reach enormous values. In addition, the order of magnitude of
Dirac's continuous creation cosmology and the temperature of the Earth
DIRAC1,2 has modified his earlier cosmological model based on the large number hypothesis3,4, that the observed approximate equalities are not accidental but causal—even though we are as yet unaware
Particle creation and Dirac's large numbers hypothesis
IN connection with cosmologies based on the large numbers hypothesis1 (LNH), Dirac2 has suggested that continuous creation of matter is required. Two modes of particle creation have been proposed and
Inflation and cosmological constant
In construction of an inflationary model, one usually assumes that the matter sector of the gravitational action is minimally coupled to the background. It means that the matter (inflaton) part of
A Time-Dependent and Cosmological Model Consistent with Cosmological Constraints
The prevailing constant cosmological model agrees with observational evidence including the observed red shift, Big Bang Nucleosynthesis (BBN), and the current rate of acceleration. It assumes that
Large numbers hypothesis. II. Electromagnetic radiation
This paper develops the theory of electromagnetic radiation in the units covariant formalism incorporating Dirac's large numbers hypothesis (LNH). A direct field-to-particle technique is used to
