It is important to take observations seriously. Many discussions of light frequency shift phenomena focus on the transformations, with more than a little implication that any observer’s stationary frame is more real than the others. So let’s take frequency shift seriously, starting with black holes.
Objects near a black hole are very large. As things get near the black hole, their light emissions are redshifted. This redshift is a real, observable indicator of the enlarged size of the object and any measurement device near it.
An interesting way of talking about its increased size is that it is less localized. The object takes up a larger volume as it falls towards the black hole. Take that to the limit! Objects sufficiently near the black hole are as large as the universe!
