In this talk, Professor Arkani-Hamed discusses how recent developments in physics suggest that spacetime and quantum mechanics may need to be removed from our understanding of the universe. He goes on to say that while this is a daunting task, it is one that scientists are constantly working on.
This video is a lecture by Professor Nima Arkani-Hamed on the end of Spacetime. He explains that the current understanding of space-time and quantum mechanics is only a glimpse of what is to come, and that a new, more radical understanding is needed. He describes some of the new mathematical structures that are involved, and explains how they can be used to generate rules of space-time and quantum mechanics.
