Fiske Planetarium at Å·ÃÀ¿Ú±¬ÊÓƵ-Boulder will host a live, multimedia presentation titled “Black Holes And Relativity” on Aug. 1 at 8 p.m.

Andrew Hamilton, an associate professor in the astrophysical, planetary and atmospheric sciences department at Å·ÃÀ¿Ú±¬ÊÓƵ-Boulder, will discuss black holes in outer space.

The presentation is based on materials originally produced by Å·ÃÀ¿Ú±¬ÊÓƵ-Boulder undergraduate students. It will feature a “fantastic but mathematically correct view of a one-way flight into a black hole,” according to Geoff Skelton of Fiske.

The program will last 90 minutes with an opportunity for questions and answers at the end. Hamilton will talk about what a black hole is, why they should be considered possible, if they really exist, where black holes are located and what is believed would happen if someone fell into one.

The presentation will feature recent Hubble Space Telescope observations of possible black holes in distant galaxies and look at other evidence of black holes in the Milky Way galaxy.

Along the way to the simulated black hole encounter, the event will demonstrate some of the mind-bending predictions of EinsteinÂ’s theories of special and general relativity.

Hamilton also is a research fellow at the Joint Institute for Laboratory Astrophysics. He has been lecturing at Fiske Planetarium for more than six years and has presented programs to public audiences on topics including Big Bang cosmology, galaxies and the structure of the universe, and black holes and relativity.

Tickets will be available from 9 a.m. to 5 p.m. and after 7 p.m. on the day of the show at the Fiske Planetarium ticket window. The cost is $3.50 for adults and $2 for children and senior citizens.
