Topological Gravity as the Early Phase of Our Universe
Prateek Agrawal, Sergei Gukov, Georges Obied +1
Motivated by string dualities we propose topological gravity as the early phase of our universe. The topological nature of this phase naturally leads to the explanation of many of…
On the Cosmological Implications of the String Swampland
Prateek Agrawal, Georges Obied, Paul J. Steinhardt +1
We study constraints imposed by two proposed string Swampland criteria on cosmology. These criteria involve an upper bound on the range traversed by scalar fields as well as a lowe…
De Sitter Space and the Swampland
Georges Obied, Hirosi Ooguri, Lev Spodyneiko +1
It has been notoriously difficult to construct a meta-stable de Sitter (dS) vacuum in string theory in a controlled approximation. This suggests the possibility that meta-stable dS…
