The really interesting thing about this is the effect it could have on space travel if applied. For example, we “know” that no spacecraft (or any other entity whose rest mass MR > 0) can achieve an instantaneous velocity V in any frame of reference such that V = c where c = the speed of light in vacuum.

But if there really IS no such thing as “instantaneous velocity”...

That's why NASA should spend some money on this, hire a physicist, and mabe a philosopher, too. Maybe there is no such thing as epitachysis and we can skip all the fire and smoke belching machinery at Cape Canaveral and just go directly to the proper velocity depending on mission requirements
