Abstract.
Gravitational waves are a unique probe of the early Universe, as the Universe is transparent to gravitational radiation right back to the beginning. Here, I will summarise some of the different scopes of primordial events that could lead to a detectable stochastic gravitational wave background. Any such background would shed light on what (if anything) lies beyond the Standard Model, sometimes at remarkably high scales. I will also briefly overview the physics behind stochastic gravitational wave background before delving deep into some of the major primordial events that can source such a background.
