“…It was totally unclear how the distant pairs of radio lobes could be related to this but we were groping for something that might supply the energy. In August 1961, I attended the IAU meeting in Berkeley where Ambartsumian (1962) emphasized the importance of activity in the nuclei of galaxies. Work inspired by him made the Byurakhan Observatory of the Armenian Soviet Socialist Republic one of the great centers of research into active galactic nuclei, producing, e.g., the Markarian and Arakelian catalogs.…”

Is space-time only brought into being by its energy content? The jury is still out, but other questions that have been with me for much of my lifegiant black holes in galactic nuclei, the formation of the Galaxy, the connection between first-order phase transitions and negative specific heats, the cause of the large-scale flow of galaxies relative to the cosmic microwave background-have all received reasonable answers. I have found great fun in understanding the dynamical mechanisms underlying such phenomena as magnetohydrodynamic jets, relativistic disks, and the bars, spirals, and chemical evolution of galaxies. The great challenges for future astronomers will be the exploration of the 96% of the Universe now believed to be neither atomic nor baryonic but perhaps partially leptonic. However, most advances do not come via frontal attack but from "bread-and-butter" investigations in related areas where observation is possible today! SCIENTIFIC PHILOSOPHYGod is truth, so the truth is a way to God. So argued the late medieval monks and it opened the way to the support of study not only in theology but also in natural philosophy (the name science was coined later). William of Occam was a monk living in Surrey in the years 1285-1349. He devised one of the most important principles for the advancement of natural knowledge. Even today, Occam's razor is often too sharp for the most imaginative but it remains a vital tool in the development of science. It does not show us a direct way to truth, but its economy of hypotheses curtails theorists' wild castles in the air. Newton (Newton 1730) thought that his studies of natural philosophy revealed something about the nature of God. By contrast, Darwin was fearful of the religious reaction to his work, which did indeed lead to a mighty revolution in theological thought that has still not percolated to all of Christendom! As scientists, we must be led by curiosity over the mechanism of the natural world, but doing bread-and-butter science, straightforward extensions of what is known in order to elucidate new phenomena, is the main job. We should not spend all our time groping at great problems that may be beyond our capacity. Too often those of great intellect spend all their time so doing, achieve little, and become disillusioned when they could have achieved much. Although few of us now see the search for a deeper understanding of natural philosophy as a search for God, to which A.S. Eddington saw parallels in his work (Eddington 1929), many of us find those parts of science that have a bearing on philosophy to be among the most interesting (e.g., Penrose 2005).Ideas are not readily described through the positions and motions of particles and fields but, as in philosophy, ideas and questioning are the gist of all science. I am not ashamed to ask questions that others claim are nonsensical and have gathered some at the end of this review. Knowing how often I have not seen the obvious implications of my own work, I regard all mankind, myself included, as somewhat sho...

“…As was shown (Barnothy and Barnothy, 1963), a consequent application of the above postulates and of the conservation laws leads to the inference that if n 0 photons of wavelength k 0 and energy E 0 are emitted by a source and have travelled for a time t before reaching the observer, the beam would contain at arrival n photons of wave length k and energy E, where …”

“…Due to the random character of the neutrino impacts, the infrared radiation produced should display a quite considerable intensity fluctuation and the sources of strong infrared radiation may have the properties of secondary nuclei within the nucleus of a galaxy. The neutrino impact could also supply an explanation of the fragmentation of protogalaxies into clusters of galaxies, of the phenomenon of supernovae and of meteor craters in which no traces of meteorites were found (Barnothy and Barnothy, 1967a).…”

“…The FIB cosmology (Barnothy and Forro, 1944) was originally developed to explain a phenomenon we found between 1928 and 1942 while registering with large coinci dence telescopes the sidereal time periodicity of cosmic radiation. This anisotropy of cosmic radiation is a Doppler effect caused through the rotation of the Galaxy.…”

“…Its existence was predicted by Compton and Getting (1935) and it was discovered by Hess in 1936. The FIB cosmology explains the flux density, the spectral characteristics and the extreme particle energies (10 21 eV) of cosmic rays arriving from outside of our Galaxy (Barnothy andBarnothy, 1963, 1967a).…”

Abstract. An attempt is made to explain Morgan cD supergiant galaxies, the microwave background radiation and extended discrete radio sources as ghost images in a universe of strong positive curvature and inhomogeneous mass distribution.The observations of Humason et al. (1956), and of Minkowski (1960) and Baum (1962) revealed that up to z = 0.46 the Hubble plot of galaxies follows the equation B = 51ogz + 23.23 ±0.13.(1)The first
