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.

A New Vision of the Early Universe starts the early expansion of the universe differently, while retaining all the evidence supporting the Big Bang Theory. In the New Vision model, the first things created are supermassive blackholes. The book provides compelling arguments for that scenario, accounting for both their massive size and early existence. The model also easily answers why the universe is so homogeneous (without inflation), and convincingly accounts for our galactic distribution in the form of the cosmic web. It also suggests answers to a dozen other mysteries plaguing cosmology and particle physics that will inspire discussion, debate, and experimentation for years to come. The model is a wellspring for inspirational thinking.A New Vision is the culmination of many years of research and study in the quest to resolve the many questions issuing from the Big Bang Theory. The work was pieced together from the reported experiments, discoveries, and observations of many well-respected particle physicists, cosmologists, and mathematicians. Their observations of how the universe works provided an excellent foundation for a new vision of the early universe.

This book presents the first comprehensive exploration of the state of this well studied and thus unsolved mystery of the value of the Hubble constant. Chapters covering data, systematics, independent methodologies, and theoretical explanations are authored by distinguished subject-matter experts. Tailored for scientists in the field or adjacent fields, this book provides a resource of insights and also an in-depth background sufficient for motivating future study. Key Features: Introduction: Written by the Nobel Laureate Adam Riess. Measurement Techniques: Gain a profound understanding of the leading Hubble constant measurement techniques, from parallax and masers to supernovae and cosmic chronometers, dissected by leading authorities on each. Systematic Errors: A deep dive into the complexities of data. Experts scrutinize potential sources of systematics that may contribute to the observed disagreements, offering a nuanced view of the challenges in Hubble constant determinations. Theoretical Explanations and Progress: A review of the theoretical explanations, some that are still standing, and some that have been ruled out; all of which have led to scientific progress toward the truth. A Comprehensive Take: This book covers every key and influential aspect to the dilemma of the Hubble tension to date and has gathered world-leading voices on each respective topic.

A.E. Taylor describes Cornford's book as "excellent piece of work, which will be found indispensable by serious students of Plato... Of course the great interest of any new commentary on the "Timaeus" must be in its handling of the metaphysical, astronomical and biological matter of the dialogue and Mr. Cornford's services in connection with all these topics are eminent." First published in 1937, the book is still considered '"...one of the masterpieces of classical scholarship...Contemporary work on the Timaeus will inevitably take Plato's Cosmology as its starting point" - Charles H Kahn, University of Pennsylvania.

This book, the first in a three-volume set, explains general relativity using the mathematical tool of differential geometry. The book consists of ten chapters, the first five of which introduce differential geometry, which is widely applicable even outside the field of relativity. Chapter 6 analyzes special relativity using geometric language. In turn, the last four chapters introduce readers to the fundamentals of general relativity. Intended for beginners, this volume includes numerous exercises and worked-out example in each chapter to facilitate the learning experience. Chiefly written for graduate-level courses, the book¿s content will also benefit upper-level undergraduate students, and can be used as a reference guide for practicing theoretical physicists.

In A Brief History of Black Holes, award-winning University of Oxford researcher Dr Becky Smethurst charts five hundred years of scientific breakthroughs in astronomy and astrophysics.Right now, you are orbiting a black hole.The Earth orbits the Sun, and the Sun orbits the centre of the Milky Way: a supermassive black hole, the strangest and most misunderstood phenomenon in the galaxy.In this cosmic tale of discovery, Dr Becky Smethurst takes us from the earliest observations of the universe and the collapse of massive stars, to the iconic first photographs of a black hole and her own published findings.A cosmic tale of discovery, Becky explains why black holes aren't really 'black', that you never ever want to be 'spaghettified', how black holes are more like sofa cushions than hoovers and why, beyond the event horizon, the future is a direction in space rather than in time. Told with humour and wisdom, this captivating book describes the secrets behind the most profound questions about our universe, all hidden inside black holes.'A jaunt through space history . . . with charming wit and many pop-culture references' - BBC Sky At Night Magazine

Martinus’ verdensbillede er unikt i verdenshistorien. Det giver et afrundet og færdigt billede af verdensaltet som et guddommeligt skaberværk, som ikke er blevet til på noget tidspunkt, men er en evig skabelse af en almægtig, alvidende og alkærlig Gud. Den evige skabelse finder sted i kredsløb, hvori de levende væsener er under stadig udvikling. Mennesket og menneskeheden gennemlever nu en mørk historisk periode med krige, sygdomme, depressioner og lidelser. Men disse tilstande er et led i en udvikling af en ny mentalitet, som afviser materiel grådighed og vold, men i stedet viser tolerance, ligeret, menneskelighed og alkærlighed. Martinus ser en strålende og lykkelig fremtid for menneskeheden og hvert enkelt menneske, når alle er kommet igennem dommedags- eller ragnarokperioden. Det enkelte individ reinkarnerer gennem historien og er med i hele udviklingsprocessen og opstandelsen til Guds rige. Dette værk i to bind er en revideret og udvidet udgave af en tidligere bog ”Martinus’ Verdensbillede” fra 2008. Udvidelsen består blandt andet i en sammenligning med fortidens store religioner og filosofier, for eksempel den kinesiske taoisme, den indiske brahmanisme, Kristus, antikkens græske filosoffer, særlig Parmenides, Platon og Plotin. Desuden med Hermesskrifterne fra Egypten, gnosticismen fra de første århundreder efter for tidsregning og med mystikere fra alle religioner. Selvom Martinus’ verdensbillede er unikt og enestående i sin helhed, kan man i de historiske religioner og filosofier finde interessante paralleller til dele af Martinus’ helhedsbillede af tilværelsen og livet. Der redegøres tillige for kristendommens historiske forhold til reinkarnation.
