The hole claim is a clear dilemma that, in general relativity, interrupted Einsten in developing his famous field formula. Some philosophers of physics have used the aforementioned hole claim to create a question mark about the principle of multi-layered materialism, the multilayered nature of events in the space-time continuum independent of the material it contains. Other philosophers and physicists disagree with this observation and characterize the hole claim as a confusion of invariance and stability in measurement.
