We don't know the infintismal or infinite ends of the electromagnetic spectrum. If the universe has boundaries, then surely there is a single standing wave that traverses it i.e. wavelength = 1 (lemmy.world)

There are the 3 considered outcomes for the universe - continued expansion, reaching a static astrophysical plane or gravitational collapse. No matter the outcome, if there is a standing wave the length (why would you have 1.5 times or anything other than 1 !?) Then under the expansion, statis and contraction scenarios, only one of these would ever reach stasis, all other scenarios have a standing wave in flux.

In ATR FTIR (attenuated total reflectance Fourier transform infra-red spectroscopy) evanescent waves penetrate outside the medium to complete the Quantisation rule. Would the same occur if we did try produce a 1.2 times wave?

Absolutely.

I read Cycles of Time by Penrose and liked what he had to say, although I did not find some arguments bullet proof. How do we test these hypotheses?

How could we interact with such large wavelengths of EM radiation?

For the short end I think high energy materials are shorter lived, so I haven't thought about this end as much.

If I generated a wavelength that was not a single multiple of the the universe (i.e. does not quantise easily into the universe) would we create evanescent like interaction with any edge?
