Das Universum 03: Der Kreislauf der Materie: Astrophysik

Prof. Dr. Harald Lesch ist Professor für Theoretische Astrophysik am Institut für Astronomie an der Ludwig-Maximilians-Universität und Professor für Naturphilosophie an der Hochschule für Philosophie in München. In der letzten Folge seiner dreiteiligen Hörbuch-Serie 'Das Universum' behandelt Harald Lesch die folgenden Themen: Sterne und Kerne Die Energie der Sterne scheint unerschöpflich. Woher kommt diese Energie? Nur ein fein abgestimmtes Gleichgewicht der Kräfte macht es möglich, dass unsere Sonne 'scheint'. Wieso sind Sterne so groß? Ein Stern ist ein gigantischer Kernreaktor in dem Kerne miteinander verschmelzen. Das Leben und Sterben der Sterne Sterne sind Gaskugeln, ihr Material entstammt großen Gaswolken. Woher kommen diese Wolken und wie entstehen in ihnen Sterne? Was passiert, wenn die Energiequellen eines Sternes versiegen? Gibt es stellare Leichen? Der große Kreislauf der Materie Bis auf Wasserstoff und Helium werden alle Elemente in Sternen erzeugt. Große Explosionen drücken die Erzeugnisse der Sterne ins Medium zwischen den Sternen. Der große Materie-Kreislauf setzt ein. Sind wir alle Sternenstaub? Von Scheiben und Kugeln Sind viele Sterne von Planeten umgeben? Wie bilden sich Planeten aus Gas und Staub? Ist unser Sonnensystem etwas Besonderes?

Kosmologie für Fussgänger: Eine Reise durch das Universum

Eine Reise durch das Universum ist dieses Hörbuch mit Harald Lesch. Er ist Professor für Theoretische Astrophysik an der Universität München und TV-Star der BR-Sendereihe 'alpha-Centauri'. Ihm zur Seite steht sein Kollege, Jörn Müller, Physiker und Astronom. Die Geheimnisse, Gesetzmäßigkeiten und Phänomene des Weltalls werden auf den irdischen Boden geholt. Für Fußgänger also. Kein Fachchinesisch, sondern Allgemeinbildungsdeutsch. Wann entstand das Universum und mit ihm Raum und Zeit? Widerspricht der Urknall der Unendlichkeit? Wie entstand unser Sonnensystem, seine Planeten und im speziellen unsere Erde? Wie wichtig ist der Mond? Vergnügliche, inhaltsreiche zwei Stunden und die beruhigende Einsicht: Im Universum tappt auch der Experte gerne im Dunkeln.

Das Universum-Paket, Teil 1 - 3: Astrophysik

In seiner dreiteiligen Hörbuch-Reihe 'Das Universum' behandelt Harald Lesch die folgenden Themen: DER ANFANG VON ALLEM Was war die Ursache für die Entstehung des Universums? Hier zeigen sich die Grenzen der physikalischen Fundamente. Nötig wäre eine Verschmelzung von Relativitätstheorie und Quantenmechanik. Aber wie? DIE EXPLOSION Zunächst war das Universum sehr klein, sehr dicht und sehr heiß. Aber dann fing es an sich wie eine Explosion auszubreiten. Und doch auch wieder nicht. Wo hinein expandiert das Universum und was passierte als es sich immer weiter ausdehnte und abkühlte? DER URKNALL Jetzt endlich sind die Kräfte da. Es beginnt sich etwas zu bilden: die Kerne von Wasserstoff- und Helium-Teilchen tauchen auf, die schon längst wieder ausgestorben sind. Eine Hierarchie der Wirkungen verändert das sich abkühlende Universum. Woher kamen die kleinen Abweichungen vom perfekten Urknall? DIE MATERIE ENTSTEHT Die Materie nabelt sich von der Strahlung ab. Die Atomkerne fangen die Elektronen ein. Das Universum ist so kalt geworden, dass sich hier und da Verdichtungen bilden, die Keime zukünftiger Galaxien. Woher kamen diese Keime und wieso ist das Universum heute so leer? DIE DUNKLE MATERIE Es gibt eine Form von Materie, die ist ganz anders. Sie sendet keine Strahlung aus und sie schluckt auch keine Strahlung. Sie ist nur schwer und viel häufiger im Universum vertreten als die normale leuchtende Materie. Ohne sie gäbe es keine Galaxien, Sterne und Planeten. Was ist das? DIE DUNKLE ENERGIE Nach Einstein entspricht Energie einer Masse. Masse aber wirkt als Schwerkraft immer bremsend auf die Ausdehnung des Universums. Seit einiger Zeit aber wissen wir, dass es noch eine andere Energieform gibt. Eine, die die Ausbreitung des Universums sogar beschleunigt.

Electric Universe: How Electricity Switched on the Modern World

In his bestselling E=mc2, David Bodanis led us, with astonishing ease, through the world's most famous equation. Now, in Electric Universe, he illuminates the wondrous yet invisible force that permeates our universe and introduces us to the virtuoso scientists who plumbed its secrets. For centuries, electricity was seen as little more than a curious property of certain substances that sparked when rubbed. Then, in the 1790s, Alessandro Volta began the scientific investigation that ignited an explosion of knowledge and invention. The force that once seemed inconsequential was revealed to be responsible for everything from the structure of the atom to the functioning of our brains. In harnessing its power, we have created a world of wonders complete with roller coasters and radar, computer networks and psychopharmaceuticals. A superb storyteller, Bodanis weaves tales of romance, divine inspiration, and fraud through lucid accounts of scientific breakthroughs. The great discoverers come to life in all their brilliance and idiosyncrasy, including the visionary Michael Faraday, who struggled against the prejudices of the British class system, and Samuel Morse, a painter who, before inventing the telegraph, ran for mayor of New York City on a platform of persecuting Catholics. Here too is Alan Turing, whose dream of a marvelous thinking machine what we know as the computer was met with indifference, and who ended his life in despair after British authorities forced him to undergo experimental treatments to cure his homosexuality. From the frigid waters of the Atlantic to the streets of Hamburg during a World War II firestorm to the interior of the human body, Electric Universe is a mesmerizing journey of discovery by a master science writer. From the Hardcover edition.

Astronomy II: Stars, Galaxies, and the Universe

As huge and prominent as it appears to us, our planet and solar system are but small parts of our galaxy, a massive assembly that spatters the sky with billions of stars and that extends away from us for tens of thousands of light years. And this galaxy of ours is in turn but a small portion of the universe of trillions of other galaxies that reaches outward for billions of light years, back to the dawn of time. This course places our local solar system into the greater context to show where it all came from and what its fate may be. We will study our sun and its interior, learn about stellar red giants, white dwarfs, neutron stars, and black holes, and encounter the mysteries of dark matter and dark energy. We explore the natures of the stars, what different kinds there are, what makes them shine, how they are born, and how they die, some with a whimper, others with explosions that rock the cosmos. We then look to our galaxy of stars, and then to the great variety of other galaxies, to their clusters, and to their fiery interactions and collisions. Finally, we encounter the universe as a whole, the collection of all there is, which is still expanding from its Big Bang origin of nearly 14 billion years ago.

The Fabric of the Cosmos: Space, Time, and the Texture of Reality

From Brian Greene, one of the world's leading physicists, comes a grand tour of the universe that makes us look at reality in a completely different way. 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? Greene uses these questions to guide us toward modern science's new and deeper understanding of the universe. From Newton's unchanging realm in which space and time are absolute, to Einstein's fluid conception of spacetime, to quantum mechanics' entangled arena where vastly distant objects can bridge their spatial separation to instantaneously coordinate their behavior or even undergo teleportation, Greene reveals our world to be very different from what common experience leads us to believe. Focusing on the enigma of time, Greene establishes that nothing in the laws of physics insists that it run in any particular direction and that time's arrow is a relic of the universe's condition at the moment of the big bang. And in explaining the big bang itself, Greene shows how recent cutting-edge developments in superstring and M-theory may reconcile the behavior of everything from the smallest particle to the largest black hole. This startling vision culminates in a vibrant eleven-dimensional multiverse, pulsating with ever-changing textures, where space and time themselves may dissolve into subtler, more fundamental entities. Sparked by the trademark wit, humor, and brilliant use of analogy that have made The Elegant Universe a modern classic, Brian Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.
