Have you ever wondered whether we are alone in the universe, or if life forms on other planets might exist? If they do exist, how might their languages have evolved? Could we ever understand them, and indeed learn to communicate with them? This highly original, thought-provoking book takes us on a fascinating journey over billions of years, from the formation of galaxies and solar systems, to the appearance of planets in the habitable zones of their parent stars, and then to how biology and, ultimately, human life arose on our own planet. It delves into how our brains and our language developed, in order to explore the likelihood of communication beyond Earth and whether it would evolve along similar lines. In the process, fascinating insights from the fields of astronomy, evolutionary biology, palaeoanthropology, neuroscience and linguistics are uncovered, shedding new light on life as we know it on Earth, and beyond.

4th book in the new 5 book Trillion Theory cosmology series by Canadian theory author Ed Lukowich.Any idea or clue as to who actually owns our universe? T Theory Says: Who Owns Our Universe, is the 4th cosmology book in the Trillion Theory 5 book series by author and Trillion Theory founder Ed Lukowich. T Theory Says, via captioned pictorials, vividly describes the origin and growth of our cosmos over the past trillion years. T Theory says also delves into the possibilities of 'who owns our universe.' T Theory provides a whole new way to see the origin and the trillion-year age of our cosmos. Black holes are shown as the builders of the spheres, solar systems, and galaxies of our gigantic cosmos. Ed says, 'T Theory acceptance will speed our discoveries across the cosmos. To fully understand black holes, and how they built our cosmos, is the key to opening doors to knowing our vast universe.' New T Theory completely disputes the claim that our universe is only 13.7 billion years old and refutes any claims that Big Bang or Nebular theory make as to how our cosmos and our solar system formed. T Theory is ready to become the new paradigm model for our cosmos and our universe.Author Biography: About the Author: Ed Lukowich began writing his new universe theory books back in 1998.

By the star physicist and author of multiple #1 Sunday Times bestsellers, a major and definitive narrative work on black holes and how they can help us understand the universe. At the heart of our galaxy lies a monster so deadly it can bend space, throwing vast jets of radiation millions of light years out into the cosmos. Its kind were the very first inhabitants of the universe, the black holes.Today, across the universe, at the heart of every galaxy, and dotted throughout, mature black holes are creating chaos. And in a quiet part of the universe, the Swift satellite has picked up evidence of a gruesome death caused by one of these dark powers. High energy X-ray flares shooting out from deep within the Draco constellation are thought to be the dying cries of a white dwarf star being ripped apart by the intense tides of a supermassive black hole ? heating it to millions of degrees as it is shredded at the event horizon.They have the power to wipe out any of the universe's other inhabitants, but no one has ever seen a black hole itself die. But 1.8 billion light years away, the LIGO instruments have recently detected something that could be the closest a black hole gets to death. Gravitational waves given off as two enormous black holes merge together. And now scientists think that these gravitational waves could be evidence of two black holes connecting to form a wormhole ? a link through space and time. It seems outlandish, but today's physicists are daring to think the unthinkable ? that black holes could connect us to another universe.At their very heart, black holes are also where Einstein's Theory of General Relativity is stretched in almost unimaginable ways, revealing black holes as the key to our understanding of the fundamentals of our universe and perhaps all other universes.Join Professors Brian Cox and Jeff Forshaw in exploring our universe's most mysterious inhabitants, how they are formed, why they are essential components of every galaxy, including our own, and what secrets they still hold, waiting to be discovered.

NEW SCIENCE / SACRED GEOMETRY "In showing the connection between the Hermetic Code and the genetic code, Michael Hayes points to the fact that the essence of evolution can also be found in religion, and therefore in the realm of the evolution of consciousness. . . . What he has discovered could be as important as the original discovery of DNA. Like Jurij Moskvitin and Jeremy Narby, he has created a new paradigm--that is, he is looking at our familiar universe from a new angle and making us aware of magical possibilities." --Colin Wilson, from the Foreword Many have observed the distinct numerical patterns embedded in ancient philosophies and religions from all over the world; others have noted that these same patterns are apparent in many of the theories of groundbreaking science. Michael Hayes reveals that there is a precise code, the Hermetic Code, that connects these patterns--information once known to ancient cultures but apparently lost over time. Mirrored in the structure of this code are the ordering principles of the universe and, intriguingly, also the harmonic ratios of music. Our notions of what is harmonious in music may therefore arise not from an abstract aesthetic sense but rather as a response to an intuition of a fundamental cosmic harmony. The resonance between biology and cosmology shows that life is music, complete with "overtones"--nowhere more strikingly present than in the helical structure of life itself: DNA. MICHAEL HAYES is an administrator at the University of Central England and is the author of The Infinite Harmony. He first recognized a common link between all major religions and esoteric doctrines while working in postrevolutionary Iran, where he was able to observe all the major religions practiced side by side. He lives with his wife and family in Birmingham, England.

In April 1992, a discovery was made that changed the way we view the world. Dr. George Smoot, distinguished cosmologist and adventurer, whose quest for cosmic knowledge had taken him from the Brazilian rain forest to the South Pole unveiled his momentous discovery, bringing to light the very nature of the universe. For anyone who has ever looked up at the night sky and wondered, for anyone who has ever longed to pull aside the fabric of the universe for a glimpse of what lies behind it. Wrinkles in Time is the story of Smoot's search to uncover the cosmic seeds of the universe. Wrinkles in Time is the Double Helix of cosmology, an intimate look at the inner world of men and women who ask. "Why are we here?" It tells the story of George Smoot's dogged pursuit of the cosmic wrinkles in the frozen wastes of Antarctica, on mountaintops, in experiments borne aloft aboard high-altitude balloons, U-2 spy planes, and finally a space satellite. Wrinkles in Time presents the hard science behind the structured violence of the big bang theory through breathtakingly clear, lucid images and meaningful comparisons. Scientists and nonscientists alike can follow with rapt attention the story of how, in a fiery creation, wrinkles formed in space ultimately to become stars, galaxies, and even greater delicate structures. Anyone can appreciate the implications of a universe whose end is written in its beginnings - whose course developed according to a kind of cosmic DNA, which guided the universe from simplicity and symmetry to ever-greater complexity and structure. As controversial as it may seem today, Wrinkles in Time reveals truths that, in an earlier century, would have doomed its proclaimers to thefiery stake. For four thousand years some people have accepted the Genesis account of cosmic origin; for most of this century, scientists debated two rival scientific explanations known as the steady state and big bang theories. And now, Wrinkles in Time tells what really happened

A half century ago, a shocking Washington Post headline claimed that the world began in five cataclysmic minutes rather than having existed for all time; a skeptical scientist dubbed the maverick theory the Big Bang. In this amazingly comprehensible history of the universe, Simon Singh decodes the mystery behind the Big Bang theory, lading us through the development of one of the most extraordinary, important, and awe-inspiring theories in science.

From Brian Greene, one of the world's leading physicists and author of the Pulitzer Prize finalist The Elegant Universe, comes a grand tour of the universe that makes us look at reality in a completely different way.Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton's unchanging realm in which space and time are absolute, to Einstein's fluid conception of spacetime, to quantum mechanics' entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.
