University of Southern Colorado
Physics Seminar will explore black holes
Pueblo -- Black Holes, perhaps the most
mysterious and least understood phenomenon in the universe, will be the topic of
the next Physics Seminar at the University of Southern Colorado. Daniel
Lesniewski, a USC chemistry major with a minor in physics, will present a
seminar titled "Cosmic Vacuum Cleaners," from noon until 12:50 p.m.,
March 13 in 103 Physics Math.
The Physics Seminars are free and open to the public. "Cosmic Vacuum
Cleaners" will explore how Black Holes are formed, the basic physics that
governs them, and the evidence for their presence. The seminar is free and open
to the public.
Black Holes are the result of supernova explosions that leave behind a fairly
massive burned out stellar remnant. With no outward forces to oppose gravity, a
breakdown of hydrostatic equilibrium occurs and the remnant collapses in on
itself. Black holes were long thought to behave like "cosmic vacuum
cleaners," sucking in surrounding matter. While that analogy may be false,
Black Holes could be the cause of the spectacular events observed in galactic
nuclei.
The University of Southern Colorado is a regional, comprehensive university
emphasizing professional, career-oriented, and applied programs. Displaying
excellence in teaching, celebrating diversity, and engaging in service and
outreach, USC is distinguished by access, opportunity, and the overall quality
of services provided to its students.
