Nonlinear gravitational-wave memory is the phenomenon whereby a passing burst of gravitational waves leaves freely-falling test masses in a different configuration than prior to the burst. Can we detect this unusual feature of general relativity? In this talk, I will dig into the memory effect to address this question. (Yes.) I will also explore other types of memory and discuss the chances that LISA or other future experiments can “remember”.
