Astrophysicist Kirill Maslennikov will give a lecture “Exotic Physics of Black Holes.” Black holes are paradoxical objects. We will discuss: what happens beyond the event horizon; why time slows down near a black hole; what a singularity is; what the temperature of a black hole means; what white holes and wormholes are. Trace from Einstein to EHT telescope and LIGO. Discuss Hawking’s contribution and quantum gravity. After: Q&A session.
