Constraint data from dark matter caused human deaths.

Macroscopic dark matter (macros) refers to a class of dark matter candidates that scatter elastically off of ordinary matter with a large geometric cross-section. A wide range of macro masses \(M_X\) and cross-sections \(\sigma_X\) remain unprobed. Over a wide region within the unexplored parameter space, collisions of a macro with a human body would result in serious injury or death. The absence of such unexplained impacts with a well-monitored subset of the human population to exclude a region bounded by \(\sigma_X > 10^{−8} − 10^{−7}\) cm2 and \(M_X < 50\) kg [1].
