Cosmology

Sie sind die wohl rätselhaftesten Dinger im Universum, beflügeln unsere Fantasie und bereiten der Forschung Kopfzerbrechen: Schwarze Löcher. Seit 100 Jahren hält uns die Vorstellung dieser lichtlosen Weltraum-Monster in Atem. In der ersten Ausgabe von „Erzähl mir alles: Physik" beleuchten wir, wie Schwarze Löcher vom theoretischen Hirngespinst zur astronomischen Tatsache wurden. Wie die Reise ins Innere eines Schwarzen Lochs wirklich aussähe, und wie die Forschung die dunklen Schwergewichte heute am Himmel dingfest macht.

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.

We have always looked up at the sky and wondered. The desire to explore and understand what lies beyond us is at the heart of scientific discovery. Ever since the ancient Babylonians tracked celestial objects on clay tablets, the search for meaning in an infinitely vast universe has been a...

Rather than celebrating or rejecting holography, it subjects its claims to disciplined evaluation, asking not whether the mathematics works, but what, if anything, it entitles us to say about reality itself. The analysis proceeds from a simple but often neglected distinction between three levels of theoretical success: mathematical consistency, explanatory power, and ontological entitlement.
