Description
The talk covers three subjects. The first is an update on collective explosion in high multiplicity pA and pp collisions. We focus on what the radial flow, more violent than cases observed before, and HBT data tell us about the sizes of those fireballs. The second is a reminder of analytic theory of small hydro perturbations of the hydro evolution, created by fluctuations of the initial conditions. Simple description of acoustic damping of fluctuating angular harmonics describe the data and give insights into simple geometry of the sound circles. The third deals with QCD and electroweak phase transitions in Big Bang: its new element is production of large wavelength sounds, which subsequently produce gravity waves. We end discussing their potential observability.
