Black hole entropy links high and low energy
The Bekenstein-Hawking result that black hole entropy equals one quarter of the horizon area in Planck units is derived using low-energy semiclassical gravity yet predicts an exponentially large number of high-energy (high-mass) states; this shows that low-energy and high-energy physics are intrinsically linked, so the effective-field-theory decoupling of scales fails for gravity.

“what we are learning, just from the thinking about black holes, that large distance or low energy and high energy are linked intuitively, and we cannot disentangle them. So this idea that one feeds into the other is crucial in this whole idea, and this has been why this picture of effective filter theory fails”
