I don't understand the THEREFORE .... Higher frequencies do mean shorter wavelengths but more of them travel in the same space ??
25000Hz or 50000Hz per second means that the wave alters its amplitude either 25000 times per second .... Long waves ... or 50000 times per second ... shorter waves. But the wave, at whatever frequency still travels the same distance in one 1 second ...
Otherwise FM radio would not work ... different frequency shifts (FM = Frequency Modulation) would cause garbage on your receiver ??

Actually, I think this is what he did say, that it caused an easier path through spacetime. Analgous to your thinner aether.

I may not be correct here, but we do receive the FULL range of frequencies. The colours we interpret are simply frequencies. Longer wavelengths we interpret as Red. Shorter as Blue.
We don't receive ONLY infrared, but as all the frequencies are 'stretched' the same as in the receding Doppler shift for sound waves, then they appear to us as 'more Red-ish' than they would to someone from whom the distant source is not receding.
But they are still the same waves!!
If you are in a really super-fast car, something capable of pulling close to 'c', then as you approach a 'red' light it will, from your view, appear green (doppler shift towards blue).
You will lose your case in court for speeding, but you will win your case for stating that the light was green. If we are ever to legally drive vehicles near 'c' speed ... all the traffic lights will have to be replaced with lights of longer (infra-infra-red ) wavelengths in order to account for the doppler shift. LOL
my thoughts only, you did invite input
