Abstract: (IOP)
In the context of large extra-dimension or TeV-scale gravity scenarios, miniature black holes might be produced in collider experiments. In many works the validity of the cosmic censorship hypothesis has been assumed, which means that there is no chance to observe trans-Planckian phenomena in the experiments since such phenomena are veiled behind the horizons. Here, we argue that 'visible borders of spacetime' (as effective naked singularities) would be produced, even dominantly over the black hol es, in the collider experiments. Such phenomena will provide us an arena of quantum gravity.
