In 1905, H. G. Wells wrote a short story titled “The New Accelerator” about the subjective effects of super speed under the influence of an accelerating serum. The Flash is the chief modern inheritor of that early speculative idea.
Perhaps Mercury was the messenger of the gods because great enough speed engages Einsteinian relativity and all its resultant paradigm shifts, which feel almost like flashes of conscious light from another dimension.
I’d like to see the Flash depicted strictly and consistently in terms of physics. At certain speeds the air would appear to him viscous, and gravity nonexistent. He might easily run right into outer space accidentally, because escape velocity is a mere 25,000 m.p.h!
Since childhood my chief fascination with drawing superheroes lay in the effort to create the feeling of movement on a static page, and no one moves like the Flash.
