Quantum genesis: The emergence of a flat universe and its mirror from nothing

I've long been fascinated by the fundamental mystery of our universe's origin. In my work, I explore an alternative to the traditional singularity-based models of cosmology. Instead of a universe emerging from an infinitely ...

Exploring the limits of power: Where quantum theory and the theory of relativity meet

Âé¶¹ÒùÔºics has a problem—their key models of quantum theory and the theory of relativity do not fit together. Now, Dr. Wolfgang Wieland from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) is developing an approach ...
