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.

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.

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.

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...

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.

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.

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.

Science Concepts Explained for Non-Scientists: Clear Guides to How the World Works Astronomy Explained for Non-Scientists: How the Universe Works From Stars and Planets to Space and Time is a clear, engaging guide designed for curious readers who want to understand the universe without advanced math, technical jargon, or a science background. Written in an accessible and concept focused style, this book explains how astronomers study space, what they have discovered about stars, planets, galaxies, and the cosmos, and how we know what we know. It transforms astronomy from an intimidating ...

Abhishek joins in with Doug from his home in India to discuss the UFO/Extraterrestrial phenomena and history in India.

Broadcaster and author Dallas Campbell joins Space Boffins Sue Nelson and Richard Hollingham to discuss NASA's new plans for Artemis, space culture, Alien and Clangers. Sue also meets the UK team working on the joint European and Chinese space weather mission, Smile.

En este episodio de PARSEC, analizamos la evolución reciente del programa Artemisa de la NASA, marcado por retrasos técnicos, problemas recurrentes en el SLS y una reestructuración significativa impulsada por Jared Isaacman.A lo largo del episodio, desglosamos los cambios en la hoja de ruta: desde el aplazamiento de Artemisa II hasta la redefinición de Artemisa III como misión de pruebas, y el nuevo objetivo de alunizaje en 2028 en un contexto de competencia entre SpaceX y Blue Origin.Tambien tratamos el trasfondo estratégico del programa lunar, incluyendo la presión geopolítica frente...

Depuis toujours, l’humanité cherche à comprendre ses origines. Mais une autre question, plus discrète et pourtant tout aussi fondamentale, mérite d’être posée : comment tout cela pourrait-il se terminer ? Contrairement aux mythes et aux prophéties, la science ne prédit pas une fin spectaculaire unique, mais explore des mécanismes réels, observables et parfois déjà en cours. Extinctions de masse, bouleversements climatiques, effondrement des écosystèmes… l’histoire de la Terre montre que la disparition n’est pas une exception, mais une règle.Aujourd’hui, les ...

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. Gerdes van der Wall vom Institut für Flugsystemtechnik (DLR) und Markus Raffel vom Institut für Aerodynamik und Strömungstechnik (DLR).

An astronomer greets visitors to a science museum in Canberra, Australia. He’s made of riveted iron plates, and he stands atop a wide ring, gazing skyward through a smaller ring in his right hand. He’s the last remnant of an historic telescope that was destroyed in a massive wildfire. The fire blazed across Australia in January of 2003. It destroyed most of Mount Stromlo Observatory, one of the major astronomy research centers in the southern hemisphere. The fire consumed five telescopes, plus a laboratory where scientists and engineers built astronomical instruments. One of the casualties...
