OUR Mission
FQxI catalyzes research and outreach primarily on questions at the foundations of physics and cosmology. FQxI supports high-risk, high-reward science—in particular new frontiers and innovative ideas integral to a deep understanding of physical reality that lie beyond the remit of conventional institutional support and funding. FQxI strives to make science more effective and equitable in all its efforts.

Video: IPI Talk – Dr. Emily Adlam: Are Entropy Bounds Epistemic?
Entropy bounds have played an important role in the development of holography as an approach to quantum gravity. In this talk I will introduce the strong and covariant entropy bounds, and then discuss how the covariant bound should be interpreted. I will argue that there is a possible way of thinking about the covariant entropy bound which would suggest that it encodes an epistemic limitation rather than an objective count of the true number of degrees of freedom on a light-sheet; thus I will distinguish between ontological and epistemic interpretations of the covariant bound. I will consider the consequences that these interpretations might have for physics and discuss what each approach has to say about gravitational phenomena. My aim is not to advocate for either the ontological or epistemic approach in particular, but rather to articulate both possibilities clearly and explore some arguments for and against them.
