These lectures feature speakers from around the country and globe. Each colloquium
lasts about an hour and gives you a deeper understanding of the types of physics and
astronomy researching going on around the world.
Colloquia will be held in a hybrid format and a recurring Zoom link is provided to access the virtual format.
The talks will be on Thursdays at 4:15PM in the Rogers Room (Jones PSC 409), unless stated otherwise.
If you are interested in being added to our e-mail distribution list regarding upcoming
colloquia, please contact Ms. Nancy Kesar via e-mail at nkesar@mailbox.sc.edu. We appreciate your interest!
Upcoming Colloquium:
The dark dimensions of the Universe
Speaker: Dr. Ignatios Antoniadis Affiliation: Laboratoire de Physique Théorique et Hautes Énergies (LPTHE) Date: 02/19/26
Abstract:
Extra dimensions are an important ingredient of theories of quantum gravity such as
string theory. If their size is large, gravity becomes strong at energies lower than
the Planck scale with important theoretical and observational consequences.
I will argue on the possibility that extra dimensions acquire large size by higher
dimensional inflation, relating the weakness of the actual gravitational force to
the size of the observable universe. Although this can be realised for any number
of extra dimensions, the requirement of (approximate) flat power spectrum of primordial
density fluctuations consistent with present observations makes this simple proposal
possible only for one or two extra dimensions at around the micron scale.
This scenario can then be nicely combined with the Dark Dimension proposal for the
cosmological constant, stemmed from the large distance swampland conjecture. I will
describe its main phenomenological consequences in particle physics and cosmology.
