  • Fakten zum Einschlafen – Das Universum

    Warum sind Galaxien nicht zufällig im Universum verstreut? - Das Gerüst aus Dunkler Materie | Fakten zum Einschlafen - Das Universum

    Bei flüchtiger Betrachtung erscheint der Nachthimmel wie eine zufällige Ansammlung von Lichtpunkten. Doch seit den 1980er-Jahren wissen Astronomen, dass diese scheinbare Willkür einer gewaltigen Architektur folgt. Galaxien sind nicht gleichmäßig verteilt, sondern bilden ein riesiges kosmisches Netz aus Filamenten, Wänden und Knoten, das riesige, nahezu leere Hohlräume umschließt. Diese Episode zeichnet nach, wie sich diese Struktur aus winzigen Quantenfluktuationen in den ersten Sekundenbruchteilen nach dem Urknall entwickelte und wie die Schwerkraft über Milliarden von Jahren aus diesen Keimen die heutige Form des Kosmos schmiedete. Dabei betrachten wir nicht nur die Geschichte dieser Entdeckung, sondern auch die raffinierten Methoden, mit denen Forscher das unsichtbare Gerüst aus Dunkler Materie kartieren. Von der Analyse des kosmischen Mikrowellenhintergrunds über den Gravitationslinseneffekt bis hin zu modernen Durchmusterungen wie dem Sloan Digital Sky Survey verfolgen wir, wie das Bild des Universums immer klarer wurde. Wir beleuchten zudem unseren eigenen Platz in dieser gewaltigen Struktur, als Teil des Laniakea-Superhaufens, der vom Großen Attraktor angezogen wird. Ich wollte verstehen, warum der Nachthimmel nicht so chaotisch ist, wie er aussieht, und wie genau die Atome in unserem Körper mit den frühesten Momenten des Kosmos verbunden sind. Es fasziniert mich, dass wir nicht nur Beobachter dieser Struktur sind, sondern selbst Knotenpunkte in diesem unermesslichen Netz aus Materie und Schwerkraft.

  • The New Quantum Era - innovation in quantum computing, science and technology

    Rational Quantum Mechanics and the Qubit Ceiling with Tim Palmer

    What if the mathematical foundation of quantum mechanics — the infinite continuum of Hilbert space — is subtly wrong, and quantum computers are about to prove it? Tim Palmer, Royal Society Research Professor Emeritus at Oxford and the physicist who revolu

  • E o Resto é... Ciência

    Quente e Frio. Quando acaba afinal este verão? Só quinta vem ar mais fresco, mas ainda não será de outono: calor no litoral e no norte

    Esta terça, metade do país estará sob aviso amarelo, só escapam Setúbal, Beja e Faro. Por 10 km/h de ventos, os Açores não viram o primeiro furacão do ano no Atlântico, muito raro nesta localização. See omnystudio.com/listener for privacy information.

No other podcast has this! https://economist.com/TOE Every episode days early, ad-free, plus my essays: https://curtjaimungal.com This episode is about what physics says is there when nobody is looking, including time itself. Jim Al-Khalili, theoretical physicist and Distinguished Professor Emeritus at the University of Surrey, joins to argue that the arrow of time is fundamental. Entropy increases because the arrow already points that way, and not the other way around. We discuss why he thinks the measurement problem is taught badly. He wants Bohmian mechanics to be right without claiming that it is, since the price is Einstein’s special relativity. He calls the past hypothesis a cheat. The conversation also covers the block universe, where he parts ways with Carlo Rovelli, and why he wants thermodynamics in the search for quantum gravity. I hope you enjoy.
