Title:
The Mysterious Nature of the Big Bang Singularity
Abstract:
100 years ago, Friedmann and Kasner discovered the first exact cosmological solutions to Einstein’s field equations, revealing the presence of a striking new phenomenon, namely, the Big Bang singularity.
Since then, it has been the object of study in a great deal of research on general relativity. However, the nature of the ‘generic’ Big Bang singularity still remains a mystery. Rivaling scenarios are abound (monotonicity, chaos, spikes) that make the classification of all solutions a very intricate problem. I will give a historic overview of the subject and describe recent progress that confirms a small part of the conjectural picture.
Short Bio:
Grigoris obtained his Ph.D. at the University of Toronto, advised by Spyros Alexakis. After graduating, he held postdoc positions at Cambridge, the Sorbonne, Princeton, and now he is an Assistant Professor in the Mathematics Department at Crete. He is originally from Athens.
