Dolores Cannon uses information obtained from regressive hypnosis to formulate a provocative viewpoint on the ancient astronaut theory of human origins. Her findings indicate that the earth was seeded eons ago by travellers from outer space. These visits by ancient extraterrestrials did not end with their intervention in human evolution. They have continued up to the present day resulting in a whole class of contemporary humans who have been subject to alien abduction.

"Dr. Ardy Sixkiller Clarke has for more than 20 years done a tremendous amount of field work and has carefully and with spiritual sensitivity collected these stories from the original witnesses. This book is an impressive documentation of the scope and depth of the UFO enigma."
--Hakan Blomqvist, Cofounder and Chairman, Archives for UFO Research (AFU), Sweden
Dr. Ardy Sixkiller Clarke, author of Encounters With Star People, vowed as a teenager to follow in the footsteps of two 19th-century explorers, John L. Stephens and Frederick Catherwood, who brought the ancient Maya cities to the world's attention. Dr. Clarke set out on a seven-year adventure (from 2003 through 2010) through Belize, Honduras, Guatemala, and Mexico, collecting stories of encounters, sky gods, giants, little people, and aliens among the indigenous people. She drove more than 12,000 miles, visiting 89 archaeological sites (Stephens and Catherwood visited only 44) and conducting nearly 100 individual interviews.
The result is an enthralling series of unique, original, true stories of encounters with space travelers, giants, little people, and UFOs. "Sky People" may very well change the way you perceive and experience the world.

Reign of the Anunnaki - The Alien Manipulation of Our Spiritual Destiny (Paperback): Jan Erik Sigdell Reign of the Anunnaki - The Alien Manipulation of Our Spiritual Destiny (Paperback)
Jan Erik Sigdell
R375 Discovery Miles 3 750 Ships in 9 - 17 working days

Reveals the ongoing alien manipulation of humanity and how we can break free Cuneiform texts found on clay plates in Mesopotamia tell us about an extraterrestrial race, called the Anunnaki, who came from space to exploit our planet. Through genetic manipulation, they created modern humans from existing earthly life forms to serve them as slaves. They physically left our planet millennia ago, but as Jan Erik Sigdell reveals, their influence and control over humanity is still pervasive and significant. Sigdell explains how the Anunnaki have maintained invisible surveillance over us as well as control over how humanity develops, setting limits on our evolution and holding back our development by means of manipulation and catastrophes, including the deluge immortalized in the Bible and many other ancient myths. He shows how they still manipulate our politics and affairs via secret societies, such as the Illuminati, and the political elite, such as the Bilderberg Group. Examining ancient descriptions of the Anunnaki as entities that resemble winged reptiles or amphibians, the author also explores their diet and how they feed off blood and the energies given off by lower life forms, such as humans, when they are expressing extreme negative emotions, having sex, or dying. * Explores how the Anunnaki have maintained invisible surveillance over us and how they control our development through religion, secret societies, and catastrophes * Reveals how they feed off our energies and how this ability has allowed them to remain here on Earth as multidimensional entities, enforcing their control invisibly * Explains how they established religion to control us and how Gnostic Christianity--which came from Christ and not the Anunnaki--offers a way out of their matrix of control

In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilisations to our existence. Of course, we don't know if such civilisations really exist. For the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the search for extraterrestrial intelligence. So far, SETI has found no evidence of extraterrestrial life, but with more than a hundred billion stars in our Galaxy alone to search, the odds of quick success are stacked against us. The silence from the stars is prompting some researchers to transmit more messages into space, in an effort to provoke a response from any civilisations out there that might otherwise be staying quiet. However, the act of transmitting raises troubling questions about the process of contact. In The Contact Paradox, author Keith Cooper looks at how far SETI has come since its modest beginnings, and where it is going, by speaking to the leading names in the field and beyond. SETI forces us to confront our nature in a way that we seldom have before - where did we come from, where are we going, and who are we in the cosmic context of things? This book considers the assumptions that we make in our search for extraterrestrial life, and explores how those assumptions can teach us about ourselves.

The Prism of Lyra is a book that examines the idea of creation in a different light. In contrast to the notion that humans are the result of creation, it explores the idea that the collective humanoid consciousness (or soul) created our universe for specific purposes. What are those purposes? Who is involved? These questions and many more are addressed, resulting in startling possibilities.

The Prism of Lyra then traces various off-planet races (Lyra, Vega, the Pleiades, Orion, Zeta Reticuli, and more) through their own evolution and ties them into the developing Earth. Highlighted is the realization of our galactic interconnectedness and our shared desire to return home.

More than half of American adults and more than seventy-five percent of young Americans believe in intelligent extraterrestrial life. This level of belief rivals that of belief in God. American Cosmic examines the mechanisms at work behind the thriving belief system in extraterrestrial life, a system that is changing and even supplanting traditional religions. Over the course of a six-year ethnographic study, D.W. Pasulka interviewed successful and influential scientists, professionals, and Silicon Valley entrepreneurs who believe in extraterrestrial intelligence, thereby disproving the common misconception that only fringe members of society believe in UFOs. She argues that widespread belief in aliens is due to a number of factors including their ubiquity in modern media like The X-Files, which can influence memory, and the believability lent to that media by the search for planets that might support life. American Cosmic explores the intriguing question of how people interpret unexplainable experiences, and argues that the media is replacing religion as a cultural authority that offers believers answers about non-human intelligent life.

R692 R621 Discovery Miles 6 210 Save R71 (10%) Ships in 18 - 22 working days

This book presents evidence that UFOs are mainly invisible and consist of both physical craft and living, biological creatures. The author convincingly shows that our atmosphere is the home of huge, invisible living organisms that are sometimes confused with spacecraft when they became visible. Mr. Constable has photographed both types of UFOs with special infrared film, some of which are reproduced in this expanded and updated edition. Despite his bold leap into the future, the general public and official ufology have a hard time accepting the evidence. In recent years teams of engineers and technicians in both Italy and Romania, unaware of Constable's earlier discoveries, obtained virtually identical infrared photos of UFOs, which were published in Italy. In 1996, NASA used ultraviolet-sensitive videotape to record swarms of invisible UFOs that looked like Constable's earlier photos. Examples from these photos are also contained in this book. Also covered are earlier pioneers into important life energies that play a big role in this research, including Wilhelm Reich, Rudolf Steiner, and Dr. Ruth B. Drown. This is an important book, recommended for those interested in the higher realms of our physical reality.

Len Kasten
R379 Discovery Miles 3 790 Ships in 18 - 22 working days

Reveals the Nazi-Reptilian infiltration of the U.S. government, their secret space program, and their slave colonies throughout the solar system. The Nazis did not really lose World War II. They made it appear that way in order to divert attention from the alliance between the Fourth Reich and the race of aliens known as the Reptilians--an ancient galactic civilization obsessed with conquest and domination. After the German surrender in 1945, the Nazi-Reptilian alliance infiltrated the U.S. military-industrial complex. Through "Operation Paperclip," the Nazis and Reptilians removed their political opponents, such as the Kennedys, and moved into policy-making positions in post-war America, infiltrating aerospace companies, banking, media, and the U.S. government, including NASA and the CIA. But their real target was not the United States--it was the solar system. As Len Kasten reveals in startling detail--including revelations of antigravity propulsion technology, alien techniques of mass mind control, and hyperdimensional teleportation capabilities--the Nazi-Reptilian alliance used their newfound power, wealth, and influence to launch a Secret Space Program with interstellar spaceports in Antarctica and on Mars as well as an eleven-story base of operations on the Moon. They commenced mining and manufacturing operations on Mars and Ceres, forming colonies there and elsewhere in the solar system. And, most shocking, they have used thousands of human slaves, easily transported in their spaceships, for both work and sexual exploitation. Sharing testimonies from American and British "supersoldiers" who participated in the "20 and Back" age-regression programs, Kasten reveals the various forces inside and outside government that are resisting the Nazis and thwarting Reptilian attempts to achieve total dominance of the planet and the solar system. The U.S.-led Secret Space Program has its own fleet of spaceships, the Solar Warden Space Armada, which patrols the edges of the solar system and poses a growing threat to the Nazi Dark Fleet. * Details "Operation Paperclip," which enabled Nazis and their Reptilian partners to infiltrate the U.S. military-industrial complex, including NASA and the CIA * Reveals their interstellar space ports in Antarctica and on Mars, their base on the Moon, and their alien technologies, including nano-technology, antigravity propulsion, mass mind control, and hyperdimensional teleportation capabilities * Shares testimonies from American and British "supersoldiers" who participated in the "20 and Back" age-regression programs, revealing advanced human technology and our Space Armada that constitutes a counter-balance to the Nazi Dark Fleet

R3,355 Discovery Miles 33 550 Ships in 18 - 22 working days

This book presents the result of an innovative challenge, to create a systematic literature overview driven by machine-generated content. Questions and related keywords were prepared for the machine to query, discover, collate and structure by Artificial Intelligence (AI) clustering. The AI-based approach seemed especially suitable to provide an innovative perspective as the topics are indeed both complex, interdisciplinary and multidisciplinary, for example, climate, planetary and evolution sciences. Springer Nature has published much on these topics in its journals over the years, so the challenge was for the machine to identify the most relevant content and present it in a structured way that the reader would find useful. The automatically generated literature summaries in this book are intended as a springboard to further discoverability. They are particularly useful to readers with limited time, looking to learn more about the subject quickly and especially if they are new to the topics. Springer Nature seeks to support anyone who needs a fast and effective start in their content discovery journey, from the undergraduate student exploring interdisciplinary content, to Master- or PhD-thesis developing research questions, to the practitioner seeking support materials, this book can serve as an inspiration, to name a few examples. It is important to us as a publisher to make the advances in technology easily accessible to our authors and find new ways of AI-based author services that allow human-machine interaction to generate readable, usable, collated, research content.

Evo-SETI - Life Evolution Statistics on Earth and Exoplanets (Paperback, 1st ed. 2020): Claudio Maccone Evo-SETI - Life Evolution Statistics on Earth and Exoplanets (Paperback, 1st ed. 2020)
Claudio Maccone
R3,947 Discovery Miles 39 470 Ships in 18 - 22 working days

This book offers a vision of how evolutionary life processes can be modelled. It presents a mathematical description that can be used not only for the full evolution of life on Earth from RNA to modern human societies, but also the possible evolution of life on exoplanets, thus leading to SETI, the current Search for ExtraTerrestrial Intelligence. The main premise underlying this mathematical theory is that the Geometric Brownian Motion (GBM) can be applied as a key stochastic process to model the evolution of life. In the resulting Evo-SETI Theory, the life of any living thing (a cell, an animal, a human, a civilization of humans, or even an ET civilization) is represented by a b-lognormal, i.e., a lognormal probability density function starting at a precise instant (b, birth) then increasing up to a peak time, then decreasing to senility time and then continuing as a straight line down to the time of death. Using this theory, Claudio Maccone arrives at remarkable hypotheses on the development of life and civilizations, the possibility of extraterrestrial life, and when computers will take over the reins from us humans (Singularity). The book develops the mathematical Evo-SETI Theory by integrating a set of articles that the author has published in various journals on Astrobiology and Astronautical Research.

Are there 10,000-year-old secret societies that still exist today?
Was there a race of giants that once inhabited the Americas?
Did ancient Egypt and ancient China have heretofore undiscovered ties?
"Lost Secrets of the Gods" delves into these ancient mysteries and many more in articles by some of the world's most intrepid and knowledgeable researchers. The old paradigms of history are being radically transformed as we discover more evidence of little-known cultures and what they achieved.
Many ancient cultures spoke and wrote of visitors that gave them knowledge and helped shape their societies. Who were they, and where did they come from?
We now know that many ancient cultures had advanced knowledge of science, agriculture, and astronomy, only some of which has been rediscovered in the last 100 years.
Were The Iliad and The Odyssey really about an epic struggle in pre-Celtic Europe? What happened to the Persian army that completely disappeared from Egypt 2,500 years ago? Did the ancients know how to create psychic guard dogs to protect sacred sites?


There is much more to history than what has officially been recorded.
"Lost Secrets of the Gods" reveals startling truths and asks fascinating questions traditional historians have long ignored.

- An awe-inspiring work of research that calls for a profound reappraisal of our role in the universe
- Over 10,000 copies sold in its first two months of release in Britain
Publication of "The Sirius Mystery" in 1976 set the world abuzz with talk of an extraterrestrial origin to human civilization and triggered a 15-year persecution campaign against Robert Temple by the KGB, CIA, NASA, and other government agencies. Undaunted, however, Temple is back, with 140 pages of new scientific evidence that makes his hypothesis more compelling than ever.
Many authors have speculated on the subject of extraterrestrial contact, but never before has such detailed evidence been presented. Temple applies his in-depth knowledge of ancient history, mythology, Pythagorean physics, chaos theory, and Greek, to a close examination of the measurements of the Great Pyramid of Giza, which was built to align directly with the star Sirius. He concludes that the alien civilization of Sirius and our own civilization are part of the same harmonic system, and are destined to function and resonate together. His findings warrant a profound reappraisal of our role in the universe.

This collection of scientific papers provides a state-of-the-art look at current knowledge on ocean worlds in our solar system and beyond. It is the result of a collaborative effort by scientists studying both terrestrial and extraterrestrial oceans, and analyzes the emergence of life and its survival on Earth as well as other potentially habitable planets and moons. The papers examine the more remote provinces of our solar system, focusing on the icy moons of the giant planets, like Europa and Titan, as well as bodies like Ceres and putative extrasolar ocean worlds. Their potential for subsurface liquid water oceans are explored, as is as their astrobiological potential. The collection also takes a look at Earth's own oceans, which offer important clues for the investigation of other ocean worlds. In addition, the collection addresses the outstanding key scientific questions and measurements, technologies and laboratory experiments necessary for the exploration of ocean worlds known today.

Starting from Newton's times this follow-up to the author's Springer book "Our Place in the Universe - Understanding Fundamental Astronomy from Ancient Discoveries" addresses the question of "our place in the Universe" from astronomical, physical, chemical, biological, philosophical and social perspectives. Using the history of astronomy to illustrate the process of discovery, the emphasis is on the description of the process of how we learned and on the exploration of the impacts of discoveries rather than on the presentation of facts. Thus readers are informed of the influence of science on a broad scale. Unlike the traditional way of teaching science, in this book, the author begins by describing the observations and then discusses various attempts to find answers (including unsuccessful ones). The goal is to help students develop a better appreciation of the scientific process and learn from this process to tackle real-life problems.

Are we alone in the universe? If not, where is everybody? An engaging exploration of one of the most important unsolved problems in science. Everything we know about how planets form and how life arises suggests that human civilization on Earth should not be unique. We ought to see abundant evidence of extraterrestrial activity-but we don't. Where is everybody? In this volume in the MIT Press Essential Knowledge series, science and technology writer Wade Roush examines one of the great unsolved problems in science: is there life, intelligent or otherwise, on other planets? This paradox (they're bound to be out there; but where are they?), first formulated by the famed physicist Enrico Fermi, has fueled decades of debate, speculation, and, lately, some actual science. Roush lays out the problem in its historical and modern-day context and summarizes the latest thinking among astronomers and astrobiologists. He describes the long history of speculation about aliens (we've been debating the idea for thousands of years); the emergence of SETI (the Search for Extraterrestrial Intelligence) as a scientific discipline in the 1960s, and scientists' use of radio and optical techniques to scan for signals; and developments in astrobiology (the study of how life might arise in non-Earth like environments) and exoplanet research (the discovery of planets outside our solar system). Finally, he discusses possible solutions to the Fermi Paradox and suggests way to refocus SETI work that might increase the chances of resolving the paradox-and finding extraterrestrials.
