Strong Gravity News & Events

In this talk, I aim to challenge persistent misconceptions surrounding Brans-Dicke and (Buchdahl's) pure Ricci-squared theories. Through concrete counterexamples in the form of new exact solutions, I will shed light on theoretical aspects related to the violation of the Weak Energy Condition, the construction of wormholes, and the revelation of novel structures within these spacetimes.

I will present recent analytical results on the evolution of the trapping horizon of a spherically symmetric black hole, as due to the
