Violent events in the very early Universe, when its age was less than 10 picoseconds, may have produced gravitational waves which can be observed in future space-based gravitational wave observatories, like the LISA satellite constellation scheduled for launch in 2034. I discuss how strong first order phase transitions produce gravitational waves, and how the signal can be used to obtain information about beyond the Standard Model particle physics.
