What's the problem?
Relativity does not give a full description of the universe, therefore it is likely that Relativity is not quite the correct description...
Your favourite Leonard Susskind made the remark that light with a wavelength longer than the diameter of a black hole would bounce off and not be trapped. Now I have no idea of the validity of this statement but it did get me thinking.Going back to the 1 hertz wave. 1 second is to 1 Planck time as 1 light second is to 1 Planck length. However if we reduce our wave to match we have an insanely high frequency. Since the Planck mass has a Scharzschild radius of two Planck lengths then the wavelength has to be 4 Planck lengths or less to be consumed. So that whatever our lower limit for wavelength turns out to be will set a lower limit on stable black holes. For if a black hole cannot trap light then is it really a black hole?

That is not a full description. Therefore it is probably incorrect! There's a flaw in the logic, I feel.
This web page just about sums up my viewpoint. Read in particular the part about primordial black holes. Note that this refers to observational data, the analysis of which produced the indicated conclusions.This is where folks like us are at a disadvantage. Not enough funds to develop or deploy measuring devices of the type required.https://medium.com/starts-with-a-bang/the-smallest-black-hole-in-the-universe-e75c4b56e538
On the premiss that a clock runs faster in the higher gravity potential, (which it does), this 'can' lead to the line of logic that... A black holes clock will run at a ridiculously faster rate than a clock on earth will, because a black holes gravity potential is that much greater.
A theory of the workings of the universe that does not fully describe the universe is incomplete, and possibly faulty...

Remember the term "potential well" - the very opposite to far space!
There are always unknowns in physics. Nothing special there. What makes your time dilate in inter-galactic voids? There has to be a cause. The function would start at a dense mass and have a positive gradient but at some unspecified point the gradient is zero and then becomes negative. Minima and maxima can indicate a connection to symmetries and conservation laws. So you have my attention...

(I can say a lot more on this but don't wish to cloud the issue).
It also requires you to look at light as having no mass.
The function of change in frequency for light is the gravitational shift for light, whereby the velocity related aspect of Doppler shift for light 'can' be transposed into time, instead of distance.Because light travels through space emitted at a whole spectrum of different frequencies that suffer Doppler shift, calculating the inverted time dilation exactly via light would not give us the exact measure, but as Hubble's candle is used for redshift...?If the hypothetical graviton exists, then it can be attributed energy and frequency that would suffer changes according to its distance from mass.The frequency in relation to a time related wave'length' would be inverted time dilation.The reason anything possessing mass increasing in time at elevation being due to adding gravity potential.

Consider a sine wave. Nothing to do with light or gravity. Forget those. If the wave length is constant we can move along the wave marking it off at regular intervals. Everything will be constant and cyclic. Now if we start again but this time continuously vary the intervals at which we mark off the wave using a function to determine the increase or decrease in the steps we can see how this can make it appear that something has changed. If we were blissfully unaware that our function existed then we may come to the conclusion that it was the wave that was changing.
Light, when looked at as having no mass, is then not affected by gravitation, and gravity potential energy is not applicable.
