Einstein's special theory of relativity made time travel to the future a possibility, and later his general theory of relativity showed us that loops in spacetime could exist, meaning that we might be able to bend time backwards, too. But what are the practicalities of making time travel possible? What do we still need to know? How do we deal with any paradoxical twists in time - and could quantum physics hold the answer?

Hello! Welcome to the StarXiv, hosted by Dr Michelle Collins and Dr Payel Das. This is a biweekly podcast that delves into the latest astronomy papers & results from the arXiv. Michelle and Payel are astronomers at the University of Surrey. They love research, but struggle to find time to read a lot of papers. They’re hoping this podcast fixes that. The beautiful logo is designed by Izzy Gray, a PhD student currently studying at the University of Surrey.

It was not easy being a woman of ambition in early 20th-century England, much less one who wished to be a scientist. Cecilia Payne-Gaposchkin overcame prodigious obstacles to become a woman of many firsts: the first to receive a PhD in astronomy from Radcliffe College, the first promoted to full professor at Harvard, the first to head a department there. And, in what has been called "the most brilliant PhD thesis ever written in astronomy", she was the first to describe what stars are made of.

A Crack in Everything is the story of how black holes came in from the cold and took cosmic centre stage. As a journalist, Marcus Chown interviews many of the scientists who made the key discoveries, and, as a former physicist, he translates the most esoteric of science into everyday language. The result is a uniquely engaging audiobook that tells one of the great untold stories in modern science.

Chasing the Moon thoroughly reimagines the race to the moon, upending much of the conventional mythology. With newly revealed stories about the space race, from its earliest days to the monumental achievement of the lunar landing in 1969, the book features a diverse cast of characters who played key roles in these historic events.

Carl Edward Sagan (November 9, 1934-December 20, 1996), born in Brooklyn, NY, was an American astronomer and astrophysicist. His best-known scientific contribution was his research on the possibility of extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by exposure to light. The following is a lecture Sagan gave in 1977 during which he discussed the place, scale and geometry of earth–the third planet from the Sun, formed 4.5 billion years ago–in our solar system.

Led by physicist James Trefil and astrophysicist Shobita Satyapal, this book traverses the incredible history of black holes and introduces contemporary developments and theories on still unanswered questions about the enigmatic objects. From the early work of Albert Einstein and Karl Schwarzschild to an insider look at black hole-galaxy connection research led by co-author Satyapa, the comprehensive book surveys an exciting and evolving branch of space science.

The product of research around the globe and interviews with dozens of prominent scientists, God's Equation tells us it is almost as though Einstein were God's mouthpiece, revealing the most fundamental truths about our larger environment, truths scientists are just now confirming.

According to Barker, who first published the book in the 1960s, Rampa's claim that his body had been taken over by a Tibetan Buddhist monk was in no way disproved. In fact, Barker provides a letter from a Tibetan Buddhist scholar stating that Rampa's writings about the inner workings of Tibetan Buddhism were quite accurate and actually revealed closely guarded secrets of the Himalayan monasteries.

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds.

Flat Earth has long been denigrated, derided, and disparaged as being the most crackpot of all conspiracy theories, marginalized, mocked, and ridiculed for centuries as being an ignorant ancient unscientific worldview, but the facts of the matter are far from what you have been told. When thoroughly examined and diligently researched with an open-mind, any skeptical critical-thinker will find it is actually the tilting, wobbling, spinning space-ball Earth promoted by NASA and taught in schools that is truly ridiculous and unscientific.

Are we alone in the universe? It's a fundamental question for Earth-dwelling humankind. Are there other worlds like ours, out there somewhere? In Hidden in the Heavens, Jason Steffen, a former scientist on NASA's Kepler mission, describes how that mission searched for planets orbiting Sun-like stars—especially Earth-like planets circulating in Earth-like orbits.

One of the leading physicists of her generation, Dr. Chanda Prescod-Weinstein is also one of fewer than one hundred Black American women to earn a PhD from a department of physics. Her vision of the cosmos is vibrant, buoyantly nontraditional, and grounded in Black and queer feminist lineages. Dr. Prescod-Weinstein urges us to recognize how science, like most fields, is rife with racism, misogyny, and other forms of oppression. She lays out a bold new approach to science and society, beginning with the belief that we all have a fundamental right to know and love the night sky.

The Los Angeles Times headline screamed: Rocket Scientist Killed in Pasadena Explosion. The man known as Jack Parsons, a maverick rocketeer who helped transform a derided sci-fi plotline into actuality, was at first mourned as a scientific prodigy. But reporters soon uncovered a more shocking story: Parsons had been a devotee of the city’s occult scene.

Take a fact-based journey through the cosmos. Tune in to hear weekly discussions on astronomical topics ranging from planets to cosmology. Hosted by Fraser Cain (Universe Today) and Dr. Pamela L. Gay (Planetary Science Institute), this show brings the questions of an avid astronomy lover direct to an astronomer. Together Fraser and Pamela explore what is known and being discovered about the universe around us. Astronomy Cast is supported thru patreon.com/AstronomyCast.

Now in its fourth edition, this low-cost astronomy audio-textbook is designed for a one-semester introductory astronomy course aimed at non-science majors and future teachers. This new edition brings the latest astronomical discoveries together with cutting-edge teaching and learning strategies designed specifically to improve student learning and retention.

En octubre de 2017, científicos del observatorio Haleakala, en Hawái, detectaron un objeto interestelar en movimiento próximo a la Tierra. Primero fue catalogado de cometa, pero esta hipótesis fue descartada. Llamado "Oumuamua", "mensajero" o "explorador" en hawaiano, finalmente fue catalogado como asteroide, si bien su forma y su comportamiento diferían del resto de los asteroides y cometas de nuestro sistema solar. Cuanto más lo observaban los científicos, más extraño les parecía.

In the year 1984, many Americans began to fear that the "surveillance state" predicted by George Orwell might be coming to pass. As a result, legendary writer and ufologist Gray Barker decided to revisit - and hopefully encapsulate - the strange case of Albert K. Bender, who was famously "hushed up" by three Men in Black in 1953 - despite heading up the largest and most successful civilian UFO organization in the world.

In The Universe, today's most influential science writers explain the science behind our evolving understanding of The Universe and everything in it, including the cutting-edge research and discoveries that are shaping our knowledge. Lee Smolin reveals how math and cosmology are helping us create a theory of the whole universe. Neil Turok analyzes the fundamental laws of nature, what came before the big bang, and the possibility of a unified theory. And much more.

In Search of a Theory of Everything takes listeners on an adventurous journey through space and time on a quest for a unified "theory of everything" by means of a rare and agile interplay between the natural philosophies of influential ancient Greek thinkers and the laws of modern physics.
