Abstract: The Universe is expanding. Unfortunately, different cosmological experiments disagree with respect to just how fast the Universe is expanding. Are these disagreements the harbinger of a new cosmological paradigm? Or is there perhaps something more subtle at play? How can these various data sets be reconciled? Come listen to a panel of eminent cosmologists discuss the measurements that have led to a possible crisis in cosmology, and how these various disparate measurements might be resolved through a new understanding of how our Universe evolves.
