DIFT Colloquium: ‘String Theory and the Dark Sector’
06/11/2025 | 15:30 - 17:30
Speaker: Cumrun Vafa (Harvard)
Venue & Time: Aula Polivalente, Plaza Mayor UAM / 15:30
Abstract: The dark sector — comprising dark energy and dark matter — has remained a profound mystery for decades. In this talk, I will review this subject and show how string theory naturally leads to a predictive framework for a unified dark sector. I will also discuss how these string-theoretic predictions align with exciting recent cosmological observations from the DES and DESI collaborations.
This seminar is related to the I+D+i project whose reference is CEX2020-001007-S, funded by MCIN/AEI/10.13039/501100011033. The topic is framed within the following research lines:
- Origin and composition of the universe: Astroparticles and Cosmology (Astro/Cosmo)
- Strings and quantum gravity (Gravity/Strings)
