[NOTE: This 1983 preprint is being uploaded to arXiv.org after the death of its author, who supported online distribution of his work. Contact info of the submitter is at this http URL .] The positions of neutron resonances have been shown to be highly sensitive to the variation of fundamental nuclear constants. The analysis of the measured isotopic shifts in the natural fossil reactor at Oklo gives the following restrictions on the possible rates of the interaction constants variation: strong…

The structure of the world from pure numbers

I investigate the relationship between physics and mathematics. I argue that physics can shed light on the proper foundations of mathematics, and that the nature of number can constrain the nature of

Feynman-Weinberg Quantum Gravity and the Extended Standard Model as a Theory of Everything

I argue that the (extended) Standard Model (SM) of particle physics and the renormalizable Feynman-Weinberg theory of quantum gravity comprise a theory of everything. I show that imposing the

Dark can’t be on the same sentence of a Hypothesis. Let’s surmise here an alternative model in which the time turn around the space with non-zero angular momentum. Then, there should be a center and

Parity-violating nuclear forces.

The first experimental observation of parity violation in nuclear forces was reported in 1964, but when this experiment was repeated elsewhere no effect was observed, and there was general disagreement between various experimental results until late 1969, when an experiment at the California Institute of Technology confirmed an earlier Russian result.

Time variation of the coupling constants

The possibility of the variation with time of the electromagnetic and strong coupling constants is investigated using nuclear systematics. Previous work by Dyson (1967) and Broulik and Trefil (see

Is the Gravitational Constant Changing

The question posed by the title is not yet conclusively resolved. Nonetheless, determinations of the lunar tidal acceleration based on dynamical time scales are now in reasonable accord with one

Evidence for large-scale uniformity of physical laws

The coincidence of redshifts deduced from 21 cm and resonance transitions in absorbing gas detected in front of four quasi-stellar objects results in stringent limits on the variation of the product

The modern study of cosmology is dominated by Hubble’s observations of a shift to the red in the spectra of the spiral nebulae—the farthest parts of the universe—indicating that they are receding

Status of Experimental Gravitation

The gist of what I am going to say is the following. 1. In recent years, a great wealth of experiments and observations related to gravity have been made and striking agreement with the theory of

Large Number Coincidences and the Anthropic Principle in Cosmology

Prof. Wheeler has asked me to say something for the record about some ideas that I once suggested (at the Clifford Memorial meeting in Princeton in 1970) and to which Hawking and Collins have

The anthropic principle and the structure of the physical world

The basic features of galaxies, stars, planets and the everyday world are essentially determined by a few microphysical constants and by the effects of gravitation. Many interrelations between

Time without end: Physics and biology in an open universe

The general conclusion of the analysis is that an open universe need not evolve into a state of permanent quiescence and life and communication can continue for ever, utilizing a finite store of energy, if the assumed scaling laws are valid.
