In this brilliant exploration of our cosmic environment, the renowned particle physicist and New York Times best-selling author of Warped Passages and Knocking on Heaven's Door uses her research into dark matter to illuminate the startling connections between the farthest reaches of space and life here on Earth.

At the end of his career, Albert Einstein was pursuing a dream far more ambitious than the theory of relativity. He was trying to find an equation that explained all physical reality - a theory of everything. Experimental physicist and award-winning educator Dr. Don Lincoln takes you on this exciting journey in The Theory of Everything: The Quest to Explain All Reality. Suitable for the intellectually curious at all levels and assuming no background beyond basic high-school math, these 24 half-hour lectures cover recent developments at the forefront of particle physics and cosmology.

All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.

Neil deGrasse Tyson has a talent for guiding readers through the mysteries of outer space with stunning clarity and almost childlike enthusiasm. This collection of his essays from Natural History magazine explores a myriad of cosmic topics. Tyson introduces us to the physics of black holes by explaining what would happen to our bodies if we fell into one; he also examines the needless friction between science and religion, and notes Earth's status as "an insignificantly small speck in the cosmos".

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?

Scientists tell us that ninety-six percent of the universe is unexplained dark matter and dark energy. Also, they admit that no unifying “theory of everything” exists in physics. This shaky foundation is the basis of modern thinking about the cosmos and Earth’s place in it. Something big seems to be missing. Thus, we’re left with no choice but to question the “consensus” cosmological model. Are we really flying through space on a spinning ball within an expanding universe, while free-falling around the Sun—all as a consequence of a “Big Bang” that supposedly occurred 13.8 billion years ago?

Hello! Welcome to the StarXiv, hosted by Dr Michelle Collins and Dr Payel Das. This is a biweekkly 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.

El siglo XX se recordará como el de la era espacial. Durante las cuatro últimas décadas, además de la inolvidable hazaña de la llegada del hombre a la Luna, se han conseguido otros importantes logros: la exploración minuciosa de Marte y Venus, la visita a los planetas gigante Júpiter, Saturno, Urano y Neptuno, el encuentro con el cometa Halley, la colocaron en órbita de grandes observatorios de rayos X que han descubierto agujeros negros invisibles y quasars lejanos… Hasta el resplandor del fósil de la creación del universo ha sido "radiografiado".

Gravity controls everything from the falling of an apple to the rising of ocean’s tides to the motions of the heavens above. If you’ve ever wondered how this most puzzling force works across our entire universe, you will be delighted by this 24-part course that is accessible to any curious person, regardless of your science education. No other product on the market presents the subject of gravity in as much detail as this course, which will follow the past 400 years of research and experimentation in the field.

We know the universe had a beginning. But what happens at the end of the story? With lively wit and wry humour, astrophysicist Katie Mack takes us on a mind-bending tour through each of the cosmos' possible finales: the Big Crunch, Heat Death, Vacuum Decay, the Big Rip and the Bounce. Guiding us through major concepts in quantum mechanics, cosmology, string theory and much more, she describes how small tweaks to our incomplete understanding of reality can result in starkly different futures.

Are you up for a trip through the ultimate neighborhood? Join astrophysicist Hugh Ross for an insider’s look at our cosmic neighborhood, where you’ll see everything from the largest-scale structure of the universe to Earth’s innermost layers. In Designed to the Core, Ross explains how the most sophisticated scientific instruments reveal exquisite “interior designs” throughout the universe that are ideally suited for human habitation here on Earth right now.

On 12th April 1981 a revolutionary new spacecraft blasted off from Florida on her maiden flight. NASA's Space Shuttle Columbia was the most advanced flying machine ever built - the high watermark of post-war aviation development. A direct descendant of the record-breaking X-planes the likes of which Chuck Yeager had tested in the skies over the Mojave Desert, Columbia was a winged rocket plane, the size of an airliner, capable of flying to space and back before being made ready to fly again.

Are we on the brink of discovering the first ever evidence that aliens exist? Join astronomer Professor Alan Duffy on his search to answer this question, as he speaks to a new generation of alien hunters embarking on the greatest hunt for extraterrestrials that’s ever been undertaken.

Les Johnson takes you on a thrilling tour of the physics and technologies that may enable us to reach the stars. He discusses the latest exoplanet discoveries, promising interstellar missions on the not-so-distant horizon, and exciting new developments in space propulsion, power, robotics, communications, and more. But interstellar travel will not be easy, and it is not for the faint of heart. Johnson describes the harsh and forbidding expanse of space that awaits us, and he addresses the daunting challenges that we need to overcome in order to realize tomorrow's possibilities.

Children's author and science communicator Lucy Hawking, daughter of Professor Stephen Hawking, invites listeners to the launch of a new space age. Fuelled by commercial finance and looking for new horizons, this is a revolutionary change from the old era in which superpowers competed for supremacy in space. Lucy is accompanied by Peter Diamandis, founder of the XPRIZE, which kickstarted the privatised space, and Kellie Gerardi, a spaceflight industry professional and trainee astronaut, as well as visionaries at the forefront of this new age of space travel.

We understand the stars at a much deeper level, not as legendary figures connected with constellations, but as engines of matter, energy, and the raw material of life itself. The Life and Death of Stars introduces you to this story in 24 half-hour lectures that lead you through the essential ideas of astrophysics - the science of stars. Your guide is Professor Stassun, an award-winning teacher and noted astrophysicist. He provides lively, eloquent, and authoritative explanations at a level suitable for science novices as well as for those who already know their way around the starry sky.

Technologically there's never been a better time to search for a new earth beyond our solar system.

Right now, you are orbiting a black hole. The Earth goes around the Sun, and the Sun goes around the centre of the Milky Way: a supermassive black hole—the strangest and most misunderstood phenomenon in the galaxy. In A Brief History of Black Holes, University of Oxford astrophysicist Dr Becky Smethurst charts the scientific breakthroughs that have uncovered the weird and wonderful world of black holes, from Hawking radiation to the iconic first photographs of a black hole in 2019.
