  The inception of a universal gravity-related irreversibility took place
originally in quantum cosmology. The ultimate reason of universal
irreversibility is thought to come from black holes close to the Planck scale.
Completely different instances of irreversibilities are quantum state
reductions unrelated to gravity or relativity but related to measurement
devices. However, an intricate relationship between Newton gravity and
quantized matter might result in fundamental and spontaneous quantum state
reduction --- in the non-relativistic Schr\"odinger-Newton context. The above
two concepts of fundamental irreversibility emerged and evolved with few or
even no interactions. The purpose here is to draw a parallel between the two
approaches first, and to ask rather than answer the question: can both the
Planckian and the Schr\"odinger-Newton indeterminacies/irreversibilities be two
faces of the same universe. A related personal note of the author's 1986
meeting with Aharonov and Bohm is appended.
