The existence of Large Extra Dimensions has been an intriguing prospect since they were first suggested. In such scenarios, the “true” Planck mass can be as low as a few TeV, and much of the large discrepancy between the observed Planck scale and the electroweak scale can be explained by geometric effects. One of the more tantalizing signatures of such scenarios is the creation of microscopic black holes in collisions of high-energy particles. I will first describe the reach of the next generation of neutrino observatories, which can probe energies far in excess of the LHC, and will describe the novel experimental signatures of microscopic black holes in neutrino telescopes like IceCube Gen2. I will end by showing that, if LEDs can be also probed at future colliders such as the FCC, these black holes can be used to detect and constrain dark matter — or any dark sector particle lighter than a few TeV — regardless of its coupling to the standard model.
