 Anthropic arguments have recently been boosted by the realization that string theory has many possible solutions, or vacua, called the “"string landscape"”, and by Steven Weinberg's prediction of the cosmological constant by anthropic reasoning.The hypothetical universe without the weak interaction is meant to serve as a counter-example to the anthropic approach to the hierarchy problem.For this “"weakless universe"”, other parameters are varied as the electroweak breaking scale is changed.
