Stellar Engineering

In terms of the scale of the galaxy, both in space and time, we humans are new comers. Though we are newly on the scene, we are already thinking about how to create large structures in space. Recently, analysis of data from one of the stars in the Kepler data set has led to speculation regarding huge artificial structures (called Stapledon/Dyson Spheres) constructed by advanced extraterrestrial civilizations. The NASA Kepler space observatory has been observing light curves of about 100,000 stars in the constellations of Cygnus and Lyre. This star, popularly dubbed “Tabby’s Star” after the first name of the astronomer leading one of the data reduction teams, shows intriguing periodic dips in its luminosity. Stellar Engineering starts by considering terrestrial organisms, and early humans, who have constructed, on their scale, “megastructures,” and continues with a history of the development of the stellar engineering concept. Kepler data on the subject star is reviewed as is observational data on other possible Stapledon/Dyson Sphere candidates. Possible applications of such enormous constructs are discussed, as well as the intriguing speculation that we might live in a Stapledon/Dyson swarm of alien space habitats within our Solar System’s Kuiper Belt. The chapter frontispiece art illuminates the ideas presented.

The growing population of engineering students who identify as Latin* are underrepresented in the field of engineering. Latin* refers to an individual of Latin American origin or descent, without restricting to a specific gender. The asterisk (*) includes related identity terms such as Latina/é/o/u/x.There is, however, a rising need to train U.S. students in engineering skills to meet the demands of our increasingly technological workforce. Structurally excluding Latin* students hinders their economic and educational opportunities in engineering. Latin* Students in Engineering examines the state of Latin* engineering education at present as well as considerations for policy and practice regarding engineering education aimed at enhancing opportunity and better serving Latin* students. The essays in this volume first consider, theoretically and empirically, the experiences of Latin* students in engineering education and then expand beyond the student level to focus on institutional and social structures that challenge Latin* students' success and retention. Finally, it illuminates emergent work and considers future research, policy, and practice.

In the 26th century, humanity relentlessly continues their fight for survival, an enduring conflict set against the backdrop of the enigmatic and ancient ringworld known as Halo. The universe of Halo is remarkably vast in scale and astonishingly elaborate in detail, telling rich stories filled with bold characters, breathtaking worlds, and thrilling conflicts. In celebration of the 20th anniversary of Halo, Dark Horse and 343 Industries have teamed up to deliver the most definitive guide to the universe thus far. Spanning over a hundred millennia and encompassing over a hundred thousand light years, the Halo Encyclopedia captures two decades of storytelling with stunning, never-before-seen art and the most detailed exploration of the universe’s many characters, worlds, and technologies to have ever been created

There are various arguments for the metaphysical impossibility of time travel. Is it impossible because objects could then be in two places at once? Or is it impossible because some objects could bring about their own existence? In this book, Nikk Effingham contends that no such argument is sound and that time travel is metaphysically possible. His main focus is on the Grandfather Paradox: the position that time travel is impossible because someone could not go back in time and kill their own grandfather before he met their grandmother. In such a case, Effingham argues that the time traveller would have the ability to do the impossible (so they could kill their grandfather) even though those impossibilities will never come about (so they won't kill their grandfather). He then explores the ramifications of this view, discussing issues in probability and decision theory. The book ends by laying out the dangers of time travel and why, even though no time machines currently exist, we should pay extra special care ensuring that nothing, no matter how small or microscopic, ever travels in time.

In this fascinating journey to the edge of science, Vidal takes on big philosophical questions: Does our universe have a beginning and an end or is it cyclic? Are we alone in the universe? What is the role of intelligent life, if any, in cosmic evolution? Grounded in science and committed to philosophical rigor, this book presents an evolutionary worldview where the rise of intelligent life is not an accident, but may well be the key to unlocking the universe's deepest mysteries. Vidal shows how the fine-tuning controversy can be advanced with computer simulations. He also explores whether natural or artificial selection could hold on a cosmic scale. In perhaps his boldest hypothesis, he argues that signs of advanced extraterrestrial civilizations are already present in our astrophysical data. His conclusions invite us to see the meaning of life, evolution and intelligence from a novel cosmological framework that should stir debate for years to come.

Experts critically examine the belief that other intelligent life exists in our galaxy.

Since antiquity, theology has frequently gone hand in hand with the study of the heavens. Speculation regarding the plurality of worlds, and the possibility of intelligent life beyond Earth, has posed questions for, and been stimulated by, Christian theology. Advancements in astronomy and astrophysics now reveal a vast universe containing trillions of galaxies. Each new exoplanet discovered brings with it a new context in which to consider the place of humanity, and the role of divinity in relation to creatures. In particular, the Christian doctrines of the incarnation and redemption must be understood afresh in light of the likelihood of extraterrestrial life. In Exotheology, Joel L. Parkyn examines the twin historic developments in scientific and theological thought on extraterrestrials from antiquity to the twenty-first century. In doing so he demonstrates a consistent pattern of theological formulations that allow for a distinct relation between Christianity and extraterrestrial life, but this has so far been without sufficient resolution. Applying concepts from anthropology, psychology and sociology to putative extraterrestrials, he explores in new depth the implications of contact, and argues for a 'divine pedagogy' of potential modalities of supernatural presence and action with extraterrestrial intelligences.
