Cosmology is both source and arbiter of some of the biggest questions in physics, such as the origin and fate of space and time, as well as the nature and evolution of everything within it. Precise observations of the cosmic microwave background and the large-scale structure of the universe have recently brought these questions into sharp focus. Although there is growing evidence that the primordial fluctuations originated from quantum fluctuations during a period of inflation, the physics of inflation remains a mystery.

Moreover, while there have been significant theoretical advances in our understanding of cosmological correlation functions, it remains challenging to isolate fundamental physics from these correlators. In particular, we don’t know the precise rules that cosmological correlators have to obey, so that, naively, it
might seem that anything goes.

This is to be contrasted with the observation that the laws of physics are a nearly inevitable consequence of quantum mechanics and special relativity. Nowhere is this seen more clearly than in the invariant observables associated with scattering amplitudes in asymptotically flat space. If cosmology is a source of ultimate questions, scattering theory can be thought of as a source of ultimate answers. Demanding only the minimal criteria of self-consistency, scattering theory has recently discovered a variety of often radically simpler ways to frame, extract, and unify predictions from physical theories. Generalizing from the relative security of flat spacetime to confront cosmological challenges provides a spectacular opportunity to stretch the applicability and reach of the S-matrix framework’s greatest ambitions.

The Simons Symposium on Amplitudes meet Cosmology will bring experts from the cosmology and scattering amplitudes communities together, at this critical time, to share their key insights and challenges, in order to synthesize their complementary perspectives. Through a series of organized discussions, the goal of the symposium is to identify a set of precise questions against which shared progress can be measured jointly in both communities. For example, we will discuss what progress will mean in the inflationary context and how this might shape collaborations at the boundaries of both fields.
