Heavy-ion collision experiments have provided overwhelming evidence\u00a0that quarks and gluons, the elementary particles within protons and\u00a0neutrons, can flow as a nearly frictionless, strongly interacting\u00a0relativistic liquid over distance scales not much larger than the size\u00a0of a proton. On the other hand, with the dawn of the multi-messenger\u00a0astronomy era marked by the detection of a binary neutron star merger,\u00a0it became imperative to understand how extremely dense fluids behave\u00a0under very strong gravitational fields. Therefore, cutting-edge\u00a0experimental apparatus in modern science, such as the Relativistic Heavy\u00a0Ion Collider (RHIC), the Large Hadron Collider (LHC), and the Laser\u00a0Interferometer Gravitational-Wave Observatory (LIGO) are now taking data\u00a0whose description requires pushing the boundaries of our current\u00a0understanding of fluid dynamics. In this talk I will discuss the new\u00a0developments that have contributed to redefine the onset of relativistic\u00a0fluid dynamics and its extension towards the far-from- equilibrium\u00a0regime. New results involving viscous fluids and their coupling to\u00a0general relativity will also be presented. These developments pave the\u00a0way for the inclusion of viscous effects in neutron star merger\u00a0simulations.<\/p>\n
