Gravitation and the Extended Uncertainty Principle

 

The Generalized and Extended Uncertainty Principles (GUP and EUP) disclose a variety of new physics over a range of length scales. The GUP probes possible Planckian transitions to a theory of quantum gravity, for which an inordinate number of studies populate the literature. Surprisingly, little attention has been paid to the EUP, since the governing length scale is taken to be Hubble sized. If this assumption is relaxed, the EUP may naturally lead to observable large-scale quantum gravity effects in supermassive black holes and other astrophysical systems. This talk will introduce the formalism of EUP enhanced gravitation and review the experimental constraints placed on each that could be tested by the LSC, Event Horizon Telescope, and other future collaborations.
