Black holes continue to mystify scientists more than a hundred years after Albert Einstein and others theorized about their existence. University of Arizona professor Sam Gralla says studying black holes has implications for challenging much of what we know about physics.
“We all dream of changing everything, and you do have to consider ideas that seem a little insane, but you have to find somewhere you can do calculations where you can ultimately make predictions for experiments," he said. "Because experiment is the ultimate arbiter of what is true.”
Gralla will be the lead-off speaker for this year’s College of Science free lecture series February 7. This year's theme focuses on surprise twists that have transformed science.
