The only beings, then, the presence of which would justify us in regarding another world as "inhabited" are such as would justify us in applying that term to a part of our own world. They must possess intelligence and consciousness on the one hand; on the other, they must likewise have corporeal...

Exoplanets: Finding, Exploring, and Understanding Alien Worlds probes the basis for possible answers to the fundamentals questions asked about these planets orbiting stars other than our Sun. This book examines what such planets might be like, where they are, and how we find them. Until around...

This book tells the incredible story of the birth of a whole new field of science called Astrobiology. In the 1990's, powerful new ground - based telescopes plus space telescopes placed in orbits high above earth's atmosphere allowed astronomers to begin discovering that our sun is not the only star in our galaxy to have planets circling it.

Did an enormous collision in the Asteroid Belt, orbiting the sun between Mars and Jupiter, bombard Earth with meteorites 470 million years ago? Astonishing new research suggests it did, and a revolutionary theory is emerging that this bombardment resulted in the single greatest increase in biological...

Making use of the laws of physical transactions, we study symmetrical many-points systems. Relation of group-theory to physical transactions in such symmetrical systems is dealt with. Studying perturbations in the stability states in the attractor-maps for transactions, approximate values of the observables...

Over some years now, a large part of the energies of the scientific community has been employed solely for finding a theory that will fit in all known happenings of the physical world. Various groups of scientists have tried to attack the problem from different ends. Some of these theories have been...

This book, which is a reworked and updated version of Steven Bloemen’s original PhD thesis, reports on several high-precision studies of compact variable stars. Its strength lies in the large variety of observational, theoretical and instrumentation techniques that are presented and used and paves...

This book is composed of two parts: First part describes basics in numerical relativity, that is, the formulations and methods for a solution of Einstein's equation and general relativistic matter field equations. This part will be helpful for beginners of numerical relativity who would like to understand...

This book is a lighthearted look at the universe and our understanding of it as provided by the mass media. This book is about the shenanigans going on in the mass media involving the subject.. All the entities of both the news and the entertainment media are in competition. The more of John Q. Public's...

Space curves around you, time slows down, particles are waves, a cat is both alive and dead. What's going on? It all starts to make sense when we untangle the universe with this clear and enlightening book. Day-dreamers and deep-thinkers, these are the concepts that will send your mind wandering to...

The aim of this book is to analyze the all important implications of Heisenberg's Uncertainty Principle for a finite universe with very large mass-energy content such as ours. The earlier and main contributors to the formulation of Quantum Mechanics are briefly reviewed regarding the formulation of...

Since Einstein first described them nearly a century ago, gravitational waves have been the subject of more sustained controversy than perhaps any other phenomenon in physics. These as yet undetected fluctuations in the shape of space-time were first predicted by Einstein's general theory of relativity,...

Low Earth Orbit (LEO) is the near Earth space zone internationally designated from 160 kilometers (99 miles) out to a distance of 2000 kilometers (1200 miles). Primarily, it is the orbital home to numerous satellites used for communication, the military, experiments, and the International Space Station....

Astronomer Peter Linde takes the reader through the story of the search for extraterrestrial life in a captivating and thought-provoking way, specifically addressing the new research that is currently devoted towards discovering other planets with life. He discusses the methods used to detect possible...
