The universe is big. Really big. And it gets bigger every day. In Cosmological Enigmas, Mark Kidger weaves together history, science, and science fiction to consider questions about the bigness of space and the strange objects that lie trembling at the edge of infinity. What are quasars, blazars, and gamma-ray bursters? Could we ever travel to the stars? Can we really expect aliens to contact us? From the profound (what evidence do we have to support the big bang theory?) to the bizarre (can there be more than one universe and, if so, how many dimensions does it possess?) to the everyday-yet-profound (why is the sky dark at night?), Kidger explains not only what we know but how we came to know it. Reflecting on how stars shine and what may lie beyond the edge of the universe, Kidger takes us on the ultimate cosmic journey. -- John Griffiths

On the astrolabe presented by the young German astronomer Regiomontanus to his ageing patron Cardinal Bessarion there is a Latin epigram and the image of an angel. The former is a geometrically-arranged acrostic with eight hidden vertical axes. Of these, the two principal ones correspond precisely to the two principal axes of the enigmatic painting �The Flagellation of Christ� by Piero della Francesca. In this are five figures in a flagellation scene on the left and three �modern� figures on the right, including a bearded Greek and an �angelic� young man in cardinal red. Over 40 interpretations of the three �moderns� have been proposed over the past 150 years. In this book, David King shows how clusters of letters across the epigram reveal double or multiple identities for each and every one of the eight persons in the painting. The only new person in the drama is Regiomontanus, whose epigram provided the inspiration for the painting. His image embodies three talented young men close to Bessarion who had recently died, and also symbolizes the cardinal's hope for the future.


In verification of the above observation , we are involuntarily guided to suggest
another solution to what was at one time an astronomical enigma , which greatly
perplexed astronomers from the time of Hipparchus , two thousand years ago ...

In a universe as large as this, it would be surprising if earth was the only inhabited planet. Everything we know about cosmology today, suggested that life should be common. Almost certainly some of that would be similar to ourselves, and would also probably be using radio technology in much the way that we do. We should be able to pick up these signals, with the powerful radio telescopes we have today, and the surprising thing is that after 50 years of continuous listening, we have not yet detected a single one. Fermis paradox relates to this finding, but in its original form, was posed as a question, as to why, in a universe such as this, we have no knowledge of the extraterrestrial life which should be common. Many answers have been proposed, none of them satisfactory, and this book looks at the changes which have taken place since Fermis day, both with respect to the origin and evolution of life, and the advancing trends in modern cosmology, to provide current information from which readers can form their own opinion. The author presents a personal view, which is hypothetical and speculative, but consistent with facts nonetheless.

In this volume readers can rediscover A.S. Eddington's elegant proof of the virial theorem for star clusters, Walter Baade and Fritz Zwicky's 1932 proposal for the existence of neutron stars, and Thomas Gold's forecast of collapsed stars as radio sources. They can reread, in the words of the canyons, pulsars, interstellar hydrogen cosmic magnetic fields, quasars, and remnant background radiation of the primeval big bang.

The planet Venus is the closest neighbour to the Earth and in several respects similar to our globe. It revolves around the Sun at an average distance of 0. 72 astronomical units, in an elliptical orbit of eccentricity 0. 007. The corresponding 3 numbers for the Earth are 1 and 0. 017. The mean density of Venus is 5. 2 g/cm , 3 that of the Earth 5. 5 g/cm . Venus’ acceleration of gravity at its equator is 8. 9 2 2 m/s , compared with 9. 8 m/s at the Earth. The escape velocity is 10. 4 km/s, while the corresponding ?gure of the Earth is 11. 2 km/s. Although the mass of Venus is somewhat smaller than that of the Earth – the ratio is M /M =0. 815 V E – the diameters of the two planets are almost the same. In other words, Venus is indeed a sister planet of the Earth. In earlier times, when almost nothing was known about the physical con- tions of Venus, the similarity appeared even stronger than today. Not only was Venus’ period of rotation thought to be close to that of the Earth, it was also p- sible (and indeed common) to imagine intelligent life on Venus.

"The dominant figures of postwar astrophysical cosmology have been the late Yakov Ze'ldovich, of Moscow, and Jim Peebles, of Princeton. But running a close third in influence has been Joseph Silk.... This collection is essential reading for the cosmological enthusiast." Nature These essays represent Joseph Silk's own meandering around cosmic themes. The topics span the beginning of time until its end and encompass the enigma of the evolution of large-scale structure, culminating in the formation of the galaxies. Dr. Silk has taken these writings from pieces written over the years, many commissioned to highlight a new look at a new discovery in cosmology. Some have been rewritten to capture a modern perspective while others remain as written to encapsulate his thoughts of a decade ago.
