Over the past decades, cosmological inflation has become a well-established paradigm for describing the early universe. Besides explaining the homogeneity and isotropy of the observed universe, it provides a simple mechanism for generating the initial conditions of the large scale structure of the universe. I will discuss how inflation can be regarded as a cosmological particle collider and how 21-cm observations from the Dark Ages could allow us to study its phenomenology, highlighting the various hurdles along the way.
