I sometimes ponder what the frequency of an EM wave with a wavelength of twice the diameter of the known universe would be, and how it would compare with the wavelength of an oscillation with a period of twice the age of the known universe. This would all be relatively easy to calculate but before doing the maths I'd rather contemplate what the implications of this would be. Tbh, I have absolutely no idea!

It would work out as a ratio - so, just a number. But what number? Would this tell us anything at all?
