Hal Haggard's Research on Black Holes Featured on PBS Space Time
Hal Haggard, associate professor of physics.
Research by Associate Professor of Physics Hal Haggard was featured on Matt O’Dowd’s PBS Space Time, an informational show that introduces viewers to concepts in astrophysics. The episode focused on an idea Haggard helped pioneer about black holes: that instead of becoming singularities at the end of their lifetime, as was previously thought, they may instead lead into cores of energy, also known as “white holes.” Haggard’s research on these structures, also known as Planck stars, and black-to-white hole tunneling was discussed in the context of physicists’ anxieties around black holes and how the perception of them has changed in previous decades. The Planck star’s existence is “one of our final hopes,” O’Dowd says. “Let’s hope they’re real, for physics’ sake.”
