TL;DR

This paper discusses the potential need for paradigm shifts in cosmology and particle physics, questioning whether current theories like Einstein's gravity and the Standard Model require modifications based on recent experimental and theoretical developments.

Contribution

It explores the possibility of paradigm shifts in cosmology and particle physics, highlighting open questions about inflation, gravity, and new particles beyond the Standard Model.

Findings

Open questions about modifications to Einstein's gravity due to inflation

Uncertainty about discovery of new particles at the LHC

Encourages theoretical exploration of alternative paradigms

Abstract

Cosmology and particle physics have long been dominated by theoretical paradigms: Einstein's general theory of relativity in cosmology and the Standard Model of particle physics. The time may have come for paradigm shifts. Does cosmological inflation require a modification of Einstein's gravity? Have experiments at the LHC discovered a new particle beyond the Standard Model? It is premature to answer these questions, but we theorists can dream about the possibilities.
