You might be pleased to know that there could be a slight chance of quartz crystal being used to create time-travel

..
Some researchers are attempting to design lattices of extremely tiny pieces of quartz crystal and sending a sound wave through them which in turn creates a sound wave in the terahertz regions (very simplistic), different frequencies are dependant on how thin or thick the quartz crystal actually is..
I have no idea what the frequency of the sound wave is that goes through the quartz crystals, neither do i know what frequencies in the terahertz regions are needed to facilitate time travel (assuming this concept could actually work)
