it is accepted that electromagnetic (EM) waves can travel through vacuum (absence of media), right? if they are indeed waves in literal sense, then shouldn't they need a medium for transmission?

so, then the riddle is how do they travel in vacuum? if u have insight that'll help me understand the propagation of EM waves in vacuum, PLEASE email me.

i've also posted this Q/riddle and the discussion continues, here.
