Going at light speed towards the future

[Stranger]

Now that'd be an interesting cusp.  If speed is the gateway then faster vibrations are synonymous to time/space and their lower equivalents are synonymous to space/time.

I wouldn't equate the speed of movement which we are discussing with rate of vibration.  I think those are distinct concepts.  
Rate of vibration is typically used to refer to one's level of spiritual development.  Movement through spacetime is unrelated to it - one can be at any level of spiritual development and travel at whatever speed.
Photons always travel at the speed of light, but at the same time can vibrate at any frequency.
