Abstract

Intergalactic gravitational radiation fields with wavelengths in the range of 1 to 10^3^ Megaparsecs have remarkable observational effects if the energy density of the fields becomes comparable to the equivalent “critical” cosmological matter density χo = 3__H__~0~^2^. In this case the perturbation in the space‐time metric caused by the radiation field is high enough to change the frequency and to shift the path of light rays of extragalactic objects in a random manner by observable amounts.

The present paper discusses the wave spectrum as a function of cosmic time and gives a statistical treatment of the redshift fluctuations.
