Disagree on the semantics. Physical realities are concepts as well. "Energy", despite being an extremely useful physical measurement, is an abstract concept. "Physical realities" and "concepts" are not mutually exclusive nor antonymous words.

In this case, the Aries/vernal point is a concept used to define coordinate systems using physical measures from Earth.
