It discussed topics in general relativity, including the possible existence of gravitational waves and ways to find a theory of quantum gravity.
Aside from the DeWitts, in the steering committee there was also Frederik Belinfante, Peter Bergmann, Freeman Dyson and John Archibald Wheeler.
Richard Feynman remembers[7] "I was surprised to find a whole day at the conference devoted to this question, and that ‘experts’ were confused.
"Felix Pirani presented for the first time how to mathematically treat gravitational waves using the geodesic deviation introduced by John Lighton Synge.
[10] When discussing the presentations of Yvonne Fourès-Bruhat and Charles W. Misner, Bruce DeWitt pointed out the importance of using computers to solve Einstein field equations.
[11][4] The relative state formulation, better known today as the many-worlds interpretation of quantum mechanics, was being developed by Hugh Everett III, a student of Wheeler, who submitted an edited version of his thesis for the conference but did not attend.
[12] Feynman publicly criticized the idea of an universal wavefunction, suggested by Wheeler, saying[12] "The concept of a 'universal wave function' has serious difficulties.
