  Time-resolved studies have so far relied on rapidly triggering a
photo-induced dynamic in chemical or biological ions or molecules and
subsequently probing them with a beam of fast moving photons or electrons that
crosses the studied samples in a short period of time. Hence, the time
resolution of the signal is mainly set by the pulse duration of the pump and
probe pulses. In this paper we propose a different approach to this problem
that has the potential to consistently achieve orders of magnitude higher time
resolutions than what is possible with laser technology or electron beam
compression methods. Our proposed approach relies on accelerating the sample to
a high speed to achieve relativistic time dilation. Probing the time-dilated
sample would open up previously inaccessible time resolution domains.
