I will discuss how multimessenger observation of Black Hole mergers and future (and current) colliders can provide complementary windows into new physics beyond the standard model. The former occurs via the possible production of black hole morsels during the merger, which

are observable via Hawking radiation at gamma ray observatories. If this phenomenon is  discovered, the Hawking spectrum close to the final evaporation of the morsels will reveal  the presence of new physics near the TeV scale. The LHC and the future collider programme, instead, provide an ideal platform to test models such as Higgs compositeness.
