Physics says there's no doubt that the universe originated in a Big Bang. There's a lot of compelling evidence for this. But it's only evidence. Furthermore, the Big Bang model has always had major problems, and now more and more new data is emerging that doesn't fit the picture. Are we on the verge of a revolution in the worldview of physics?

Man merkt, dass wir kurz vor einem Umbruch im Weltbild stehen könnten, weil die alten Erklärungen einfach nicht mehr alles abdecken. Ein absolut fesselndes Thema, das einem wieder vor Augen führt, wie wenig wir letztlich wirklich über den Ursprung von allem wissen.
Chapeau Professor, Sie haben wirklich Humor!

Ein Vortrag ohne KI, dafür aber kompetent vorgetragen.
Das gibt's heutzutage nur noch ganz selten.
