Weekly Space Hangout: Do Black Holes Grow as the Universe Expands? Dr. Kevin Croker Explains Cosmological Coupling

December 29, 2021 @ 8:00 pm - 9:00 pm EST

This week marks the final episode of 2021, and we are excited to welcome Dr. Kevin Croker from University of Hawai’i at Mānoa! Kevin led a team that compared data from simulated black hole mergers with that from gravitational waves detected by the LIGO–Virgo collaboration. This comparison led to a surprising conclusion: ignoring the expansion of the universe may be limiting the scientific understanding of black-hole physics. The team hypothesizes that that as the universe expands outward following the Big Bang, all objects with mass grow as well – and Black Holes are no exception. This new process has been dubbed “Cosmological Coupling.”
