  Several works in the last few years devoted to measure fundamental probes of
contemporary cosmology have suggested the existence of a delocalized dominant
component (the "dark energy"), in addition to the several-decade-old evidence
for "dark matter" other than ordinary baryons, both assuming the description of
gravity to be correct. Either we are faced to accept the ignorance of at least
95 % of the content of the universe or consider a deep change of the conceptual
framework to understand the data. Thus, the situation seems to be completely
favorable for a Kuhnian paradigm shift in either particle physics or cosmology.
We attempt to offer here a brief discussion of these issues from this
particular perspective, arguing that the situation qualifies as a textbook
Kuhnian anomaly, and offer a tentative identification of some of the actual
elements typically associated with the paradigm shift process "in the works" in
contemporary science.
