LANL Frontiers in Science Lecture: Matter, Antimatter and Surviving the Big Bang


LANL News:

  • Talk begins at 7 p.m. and is open to public

Los Alamos National Laboratory scientist Vincenzo Cirigliano asks the question, How did we survive the big bang? in a series of Frontiers in Science lectures beginning Monday, Nov. 4, in the Duane Smith Auditorium at Los Alamos High School.

“Particles and antiparticles were produced in equal numbers in the aftermath of the big bang,” according to Cirigliano. “As the primordial soup cooled, they should have completely destroyed each other, leaving behind a universe with no matter. Instead, an imbalance of matter over antimatter developed, eventually leading to galaxies and stars and planets … and us.”

Cirigliano will explore how this asymmetry arose and whether the known laws of physics can explain how matter survived the big bang.

Other Frontiers in Science lectures are scheduled for 7 p.m. at the following locations:

Nov. 6, New Mexico Museum of Natural History and Science, 1801 Mountain Road N.W., Albuquerque

Nov. 8, James A. Little Theater, New Mexico School for the Deaf, 1060 Cerrillos Road, Santa Fe

Nov. 15, Taos Convention Center, 120 Civic Plaza Drive, Taos.

Sponsored by the Fellows of Los Alamos National Laboratory, the Frontiers in Science lecture series is intended to increase local public awareness of the diversity of science and engineering research at the Laboratory. All talks in the Frontiers in Science lecture series are free of charge.
