The ATLAS experiment at CERN's Large Hadron Collider (LHC) continues to explore our femtoscopic universe by searching for exotic new particles. Discovering these minuscule motes of matter would have a tremendous impact on our understanding of the universe as a whole: potentially unraveling the secrets of dark matter or the source of the Higgs boson mass. In this seminar we will dive into the latest results of searches with top quark signatures. We'll also look forward to future detectors, discussing both the ATLAS detector upgrade for the High-Luminosity LHC and prospects for future colliders. The Allegro detector concept at a possible future circular collider at CERN will be presented.
