The Large Hadron Collider, the largest machine ever built, is now deep into its mission to explore physics scenarios at the TeV scale. In a triumph for the Standard Model of particle physics, the LHC has confirmed the existence of the Higgs Boson. However, mysteries about fundamental physics abound. As motivations to posit new physics extending the Standard Model remain manifold, the LHC is an invaluable tool for investigating fundamental theories. By the end of its lifetime LHC will have completed its High Luminosity run and have taken a staggering amount of data. In the total timescale of LHC's run, new physics may be discovered at any time, many scenarios will be ruled out, and some will not reach the threshold of detectability. In this talk I will explore the prospects for new physics discovery and theory selection as Beyond the Standard Model scenarios confront the full high luminosity run of the LHC.
