its all part and parcel of the same thing. Energy, frequently[sic] and vibration. 'Zackly! Energy ebbs and flows.  The rate at which it does this is the frequency.  If it's in a range that can be felt, it's called vibration.  The range where it can be seen is called light.  The range where it can be heard is called sound.  Frequency ranges above and below these also have names, like radio or microwave, xrays, etc., but it's all energy. The story you reference was a 23 part series that Ben has condensed into a one-hour vid on the Catastrophe Cycle called COSMIC DISASTER | CIA: classified.  Definitely on the must-watch list.  Thanks for the reminder.
