Prof. Daniel Holz
discusses a new way to calculate the Hubble constant, a crucial number that measures the expansion rate of the universe and holds answers to questions about the universe's size, age and history. "In a flash, we had a brand-new, completely independent way to make a measurement of one of the most profound quantities in physics. That day I'll remember all my life," said Holz.
