Quanto è grande l'universo? C'è stato un inizio e ci sarà una fine? Come si è fatta strada l'ipotesi del Big Bang? Come si fa a scoprire il passato dell'universo e a prevederne l'evoluzione futura? Domande antiche e in parte ancora irrisolte. Nel volume i passi più importanti del lungo cammino scientifico dall'età moderna fino alle scoperte più recenti, riguardanti la gerarchia di strutture cosmiche, l'espansione dell'universo, lo stato iniziale ultracaldo e ultradenso, che oggi i cosmologi possono osservare direttamente grazie a sofisticati telescopi e strumenti spaziali.

Of all the things we know about the universe, what do we really know about the nature of space? For example, is there a beyond space? Can space exist in the absence of matter? Though it may seem like a dumb question - 'where' does space come from? This essay takes a look at what some scientists have to say on this issue; the work also contains many references on the topic of spacetime and relativity, which should be useful to physics students.

L'Universo ha 13,8 miliardi di anni. Da quando si è formata, la Terra ha compiuto intorno al Sole quattro miliardi e mezzo di orbite. È un tempo impensabile, un tempo infinito. Un tempo che gli esseri umani non hanno occupato che per la più piccola delle frazioni. Eppure, da quando siamo comparsi sulla faccia del pianeta, da quando abbiamo iniziato ad accendere fuochi per tenere a bada la notte, non abbiamo mai smesso di alzare gli occhi alla volta senza confini. A meravigliarci per tutto quell'infinito sopra di noi, per tutto quello che non possiamo vedere.

Just trying to define a man who had the qualities of a mathematician, astronomer, philosopher, inventor, and astrologer can prove difficult. But all of that can be ascribed to Johannes Kepler, one of the giants of his era who ushered in the Scientific Revolution and is often considered the first modern scientist.

The #1 New York Times bestseller from David McCullough, two-time winner of the Pulitzer Prize—the dramatic story-behind-the-story about the courageous brothers who taught the world how to fly—Wilbur and Orville Wright. On a winter day in 1903, in the Outer Banks of North Carolina, two...

Ripples in Spacetime is an engaging account of the international effort to complete Einstein's project, capture his elusive ripples, and launch an era of gravitational-wave astronomy that promises to explain, more vividly than ever before, our universe's structure and origin. The quest for gravitational waves involved years of risky research and many personal and professional struggles that threatened to derail one of the world's largest scientific endeavors.

In the most authoritative book ever written about Apollo, David Whitehouse reveals the true drama behind the mission, telling the story in the words of those who took part - based around exclusive interviews with the key players. This enthralling book takes us from the early rocket pioneers to the shock America received from the Soviets' launch of the first satellite, Sputnik; from the race to put the first person into space, through President Kennedy's enthusiasm and later doubts, to the astronauts' intense competition to leave the first footprint.

Is time travel possible? What does it mean to say the universe is fine-tuned? Could our universe be fake? Or, if it is real, is it part of a multiverse? In an attempt to solve such mysteries, leading experts attempt to break the world down to its smallest particles and build it back up - to understand the universe by understanding the atom. In this compelling audio course, Dr. Robert Lawrence Kuhn, creator and host of the PBS series Closer to Truth, examines the riddles of the universe with 13 luminaries in physics, cosmology, astronomy, philosophy, mathematics, and chemistry.

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.

The Earth, that trusty old spinning marble we call home, isn't a sphere at all. No, according to some, it is flat as a pancake (or a pizza, if we're being generous). Yet for thousands of people, this is reality – or at least their version of it. The Flat Earth phenomenon isn't new. It has ancient roots, woven into the cosmologies of civilizations long past. But what's fascinating is how, in a time when we can send rovers to Mars, carry pocket supercomputers, and live-stream cat videos from space stations, this belief has not only persisted but thrived.

A century ago very few people dreamed of space travel. Today it is the most daring and technologically sophisticated quest ever undertaken, being driven not just by government agencies such as NASA and ESA, but also by visionaries such as Richard Branson (Virgin Galactic), Elon Musk (SpaceX) and Jeff Bezos (Blue Origin). To mark the 50th anniversary of the 1969 moon landing, this major drama-documentary series charts the definitive story of the past, present and future of humankind’s exploration of space. The Space Race is narrated by Kate Mulgrew and features a full cast.

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.

Imagine a region in space where the force of gravity is so strong that nothing - not even light - can escape. This phenomenon is a black hole: one of the most exotic, mind-boggling, and profound subjects in astrophysics. Nearly everyone has heard of black holes, but few people outside of complex scientific fields understand their true nature and their implications for our universe. No movie, novel, or other fictional treatment of black holes matches Professor Filippenko’s absorbing presentation of the actual science behind these amazing objects.

Astronomers have recently discovered thousands of planets that orbit stars throughout the Milky Way. Much of what has captured the imagination of planetary scientists and the public is the unexpected strangeness of these distant worlds. The quest to find other worlds brims with possibility, and Donald Goldsmith presents the science of exoplanets and the search for extraterrestrial life in a way that even Earthlings with little to no background in astronomy or astrophysics can understand and enjoy.

Quasars are the brightest sustained phenomena in the known universe—engines of light powered by supermassive black holes devouring matter at the centers of distant galaxies. But they are more than cosmic spectacles. Every beam of quasar light that crosses the universe accumulates an extraordinarily detailed record of the gas, matter, and structure it passes through. The intergalactic medium writes its autobiography in the spectra of quasars, using absorption lines as words and sightlines as sentences.

In the gripping Never Panic Early, Fred Haise, Lunar Module Pilot for Apollo 13, offers a detailed firsthand account of when disaster struck three days into his mission to the moon. An oxygen tank exploded, a crewmate uttered the now iconic words, “Houston, we’ve had a problem here,” and the world anxiously watched as one of history’s most incredible rescue missions unfolded. Haise brings listeners into the heart of his experience on the challenging mission—considered NASA’s finest hour—and reflects on his life and career as an Apollo astronaut.

What’s so funny about space and science? Our season finale features the incomparable comedian Joan Rivers. In this episode, she provides color commentary for a Red Carpet parade of previous show topics, including space tourism, the anniversary of Apollo 11, and the search for alien life (both in space and in Hollywood).

A sweeping account of the century of experimentation that confirmed Einstein's general theory of relativity, bringing to life the science and scientists at the origins of relativity, the development of radio telescopes, the discovery of black holes and quasars, and the still unresolved place of gravity in quantum theory.
