What is a White Hole? - Exploring Black Holes and Quantum Gravity

Embark on a mind-bending journey into the depths of black holes and the emergence of white holes in this captivating lecture by renowned physicist Carlo Rovelli. Explore the circular appearance of black holes, the experience of traveling into one, and the bizarre space within. Delve into quantum gravity, loop quantum theory, and the concept of quantum jumps leading to white holes. Discover how these ideas challenge Einstein's theory and ponder the formation time of white holes. Examine the evidence supporting white hole theory, its connection to dark matter, and the potential for detection. Throughout this intellectual adventure, gain insight into the nature of scientific exploration as a form of mind travel, pushing the boundaries of our understanding of the universe.

Steeped in nearly two centuries of tradition, a Discourse is more than just a lecture. To keep the focus on the topic, presenters begin sharply at pm without introduction and we lock the speaker into a room ten minutes ahead of the start legend has it that a speaker once tried to escape!. Some of our guests dress smartly for our Discourse events to add to this sense of occasion.
