Abstract We use gauge/gravity duality to study the dynamics of strongly coupled gauge theories undergoing boost invariant expansion in an arbitrary number of space-time dimensions (D).By eeboo coupons keeping the scale of the late-time energy density fixed, we explore the infinite-D limit and study the first few corrections to this expansion.In agreement with other studies, we find that the large-D dynamics are controlled by hydrodynamics and we use our computation to constrain the leading large-D dependence of a certain combination of transport coefficients up to 6th order in gradients.Going beyond late time physics, we discuss how non-hydrodynamic modes appear in the johnny cash style clothing large-D expansion in the form of a trans-series in D, identical to the non-perturbative contributions to the gradient expansion.We discuss the consequence of this trans-series in the non-convergence of the large-D expansion.
