This woman communicated with beings from another world, handed over impossible technology, and vanished without a trace. One of the most enigmatic cases ever recorded. Did she leave… or did they come for her?https://www.viajealodesconocido.orghttps://www.youtube.com/viajealodesconocido

What is the nature of space and time? How do we fit within the universe? How does the universe fit within us? There's no better guide through these mind-expanding questions than acclaimed astrophysicist and best-selling author Neil deGrasse Tyson. But today, few of us have time to contemplate the cosmos. So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in digestible chapters consumable anytime and anywhere in your busy day.

Cosmos is one of the bestselling science books of all time. In clear-eyed prose, Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space.

By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know it happened at all? Here prominent cosmologist Niayesh Afshordi and science communicator Phil Halper offer a tour of the peculiar possibilities: bouncing and cyclic universes, time loops, creations from nothing, multiverses, black hole births, string theories, and holograms. Along the way, they offer both a call for new physics and a riveting story of scientific debate.

How can we make intelligent decisions about our increasingly technology-driven lives if we don’t understand the difference between the myths of pseudoscience and the testable hypotheses of science? Pulitzer Prize-winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions.

Reality is not what it seems. Not fixed. Not silent. Not separate from the one who observes it. Quantum experiments reveal seams in the world… places where information appears without traveling… where outcomes wait for attention… where time behaves like something far more flexible than a river. These seams form a doorway. A narrow line where darkness gives way to light… where the familiar dissolves into the possible… where a question becomes the beginning of understanding. This book does not claim answers. It offers a key. If you have ever sensed something beneath the surface… Step closer.

America’s favorite astrophysicist has written the most entertaining and universally appealing book of his stellar career: a practical guide for dealing with Alien visitors, an exploration of how it might happen, and a cultural history of our fascination with extraterrestrials. “Ever since...

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.

"It doesn't take an Einstein to understand modern physics," says Professor Wolfson at the outset of these 24 lectures on what may be the most important subjects in the universe: relativity and quantum physics. Both have reputations for complexity. But the basic ideas behind them are, in fact, simple and comprehensible by anyone. These dynamic and illuminating lectures begin with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics.

Where do you go to let your curiosity fly? The backyard, of course. The setting for this audio original program is the backyard of William Shatner’s Los Angeles home, where he and Neil deGrasse Tyson enjoy a powerful, open-hearted conversation steeped in wonder. Having become fast friends and verbal sparring partners, the two men discuss the quest for knowledge that has driven human exploration and discovery over centuries, drawing from historical and contemporary examples.

A bold and all-embracing exploration of the nature and progress of knowledge from one of today's great thinkers. Throughout history, mankind has struggled to understand life's mysteries, from the mundane to the seemingly miraculous. In this important new book, David Deutsch, an award-winning pioneer in the field of quantum computation, argues that explanations have a fundamental place in the universe.

A Russian dissident, a Jesuit priest, and an American mule skinner are but a few of the bold visionaries who crafted the scientific story of cosmic origins. The collective insights of these and numerous creative thinkers advanced human understanding from mythology to mathematics, yielding falsifiable alternatives to ancient folklore and campfire tales. Listening to the Big Bang tells the dramatic human story—filled with colorful characters, unsung catalysts, and glorified heroes—which made the Big Bang the leading cosmological theory.

Welcome to the Universe is a personal guided tour of the cosmos by three of today's leading astrophysicists. Inspired by the enormously popular introductory astronomy course that Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott taught together at Princeton, this book covers it all - from planets, stars, and galaxies to black holes, wormholes, and time travel.

Told in language we all can understand, A Brief History of Time plunges into the exotic realms of black holes and quarks, of antimatter and "arrows of time," of the big bang and a bigger God—where the possibilities are wondrous and unexpected. Stephen Hawking brings us closer to the ultimate secrets at the very heart of creation.

In Neil deGrasse Tyson’s delightful journey through the cosmos, his fictional character Merlin responds to popular questions asked by adults and children alike. Merlin, a timeless visitor from Planet Omniscia in the Andromeda Galaxy, has observed firsthand many of the major scientific events of Earth’s history.

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.

Mercury, a lifeless victim of the Sun’s expanding power. Venus, once thought to be lush and fertile, now known to be trapped within a toxic and boiling atmosphere. Mars, the red planet, doomed by the loss of its atmosphere. Jupiter, twice the size of all the other planets combined, but insubstantial. Saturn, a stunning celestial beauty, the jewel of our Solar System. Uranus, the sideways planet and the first ice giant. Neptune, dark, cold and whipped by supersonic winds. Pluto, the dwarf planet, a frozen rock.

This episode explores the science of time dilation and why time does not pass at the same rate for everyone.Based on Einstein’s relativity, we examine how speed and gravity distort time, a phenomenon confirmed by atomic clock experiments and particle physics.The discussion also reveals why technologies like GPS satellites must constantly correct for relativistic effects.Finally, we explore the famous twin paradox and what time distortion could mean for future deep-space travel—raising deeper questions about whether the flow of time itself is just a human illusion.This episode includes ...

Hubschrauber sind laut. Richtig laut. 85-100 Dezibel – das ist Presslufthammer-Niveau. Doch das DLR arbeitet an einer Lösung: Rotorblätter mit eingebauten Piezomaterialien, die sich wie künstliche Muskeln bewegen.
