Did the big bang violate the laws of thermodynamics? Why did the Universe have such low entropy at that time? Are the laws of physics consistent across the multiverse?
Sean Carroll discusses the laws of thermodynamics and their place in the Universe. How did the Universe as we know it start in a state of such low entropy? Can we see evidence of other regions of the multiverse? Do we expect the laws of physics to be conserved across the multiverse?
Sean Carroll is a theoretical physicist who thinks about the fundamental laws of nature, especially as they connect to cosmology. Watch his past Ri lectures on black hole firewalls and the particle at the end of the universe.
