String Theory and the First Half of the Universe

Fien Apers


I will describe a stringy exotic epoch in the early universe that connects the end of inflation to the start of the standard radiation dominated epoch. Rolling scalar fields play a crucial role in this epoch that could last as long as half the lifetime of the universe on a logarithmic scale. As the energy scales at the endpoints of this epoch can be largely different, there is a possibility of traversing multiple transplanckian distances and perhaps producing quantum gravity signatures
