On the third day of HowTheLightGetsIn, the Arena was buzzing with those brave souls wishing to see the clash of titans over string theory. An extraordinary panel: Nobel Laureate Roger Penrose, pioneering string theorist Tasneem Zehra Husain, Polymath Mathematical Physicist Eric Weinstein and the ground-breaking string theorist Brian Greene. The panelists gathered at HTLGI to debate the trouble with String Theory, theory or framework, community or oligarchy, a beautiful theory or one detached from reality.

String theory, heralded as a potential theory of everything, has dominated theoretical physics for over thirty years, with more scientific papers arising from it than any other theory. But critics argue the theory has held undue influence and proclaimed that it is an error to pursue it. String theory proposes 11 dimensions and a vast landscape of possible universes without any evidence. Moreover, a theory of everything has not been forthcoming, and predictions of supersymmetry particles have not been confirmed.
