TASI Lectures on Cosmic Signals of Fundamental Physics

Understand

The history of the Universe and the forces that shaped it are encoded in maps of the cosmos.

• From understanding these maps, we gain insights into nature that are inaccessible by other means.
• Unfortunately, the connection between fundamental physics and cosmic observables is often left to experts (and/or computers), making the general lessons from data obscure to many particle theorists.
• Fortunately, the same basic principles that govern the interactions of particles, like locality and causality, also control the evolution of the Universe as a whole and the manifestation of new physics in data.
