Science Saturday: Two Ways to Make a Black Hole

  • Saturday, June 08, 2019
  • 2:30pm - 3:30pm

Two Ways to Make a Black Hole — And See It!

Dr. Dan Reichart will discuss what a black hole is, and two ways to make them. The first is the collapse of a massive star, which sometimes results in a gamma-ray burst (GRB). The second is the merger of binary neutron stars, which results in a burst of gravitational waves and a kilonova (and possibly also a GRB). We will discuss the roles that Dr. Reichart played in locking down both of these physical pictures, including linking GRBs to supernova explosions, and hence to the collapse of massive stars, in 1999; the discovery of the most distant explosion in the universe then known, in 2005; and the discovery of the first optical counterpart (a kilonova) to a gravitational-wave event in 2017. Lastly, Dr. Reichart will also present our plans for discovering more of these, and possibly even measuring Hubble’s Constant in a new way, moving forward.

Science Saturday is a series of lectures and demonstrations that are held on a Saturday each month in the SECU Daily Planet Theater at 2:30pm. The presentations are meant to demonstrate the vast variety of careers in scientific fields, from astronomy to zoology, and are most appropriate for ages eight and older. Meet a scientist, learn about current research and ask your questions!
