  A very brief overview is presented on some of the current most active areas
of research in formal aspects of High Energy Physics and Cosmology. Including
the recent breakthrough on the black hole information paradox, developments on
amplitudes, the bootstrap and swampland programmes as well as progress towards
realistic UV complete models of particle physics and cosmology. Perspectives on
future contact with observations are discussed, emphasising the long term
prospect for ultra high frequency gravitational waves to test early universe
physics beyond the Standard Model.
