Are Black Holes Elementary Particles?

Speaker:Prof. Yuan K. Ha
Affiliation:Temple University, USA
Date:December 5, 2008 (Fri)
Time:4:00-5:00 p.m.
Venue:Room 522, 5/F, Chong Yuet Ming Physics Building, HKU


Quantum black holes are the smallest and heaviest conceivable elementary particles. They have a microscopic size but a macroscopic mass. Several fundamental types have been constructed with some remarkable properties. Quantum black holes in the neighborhood of the Galaxy could resolve the paradox of ultra-high energy cosmic rays detected in Earth's atmosphere. They may also play a role as dark matter in cosmology.

Coffee and tea will be served 20 minutes prior to the seminar.
