Consistency of de Sitter vacua in string theory KU Leuven
The experimental proof for the existence of positive vacuum energy in the universe is overwhelming. In the context of string theory this implies that we need to search for low energy states of the universe with positive vacuum energy, called de Sitter vacua. One of the ruling ideas is that string theory contains an extremely large quantity of such vacuum states, named the landscape. If correct this changes drastically how we should address ...
