Episode 159: Living on the Edge: Are We On the Boundary of an Expanding Universe?, with Ulf Danielsson

Feature Guest: Ulf Danielsson

Our universe is big. But what if all of this was just one of an unimaginably large number of bubble universes. That’s the proposal by a group of scientists who recently introduced a new model for the universe which for the first time links string theory with dark energy and higher dimensions. But how does it compare to rival multiverse theories? Today we’re joined here at The Star Spot by physicist Ulf Danielsson to explain how his model, uniquely, provides for universes that far from being isolated might actually come into contact.
