What is the antonym of horoscope?

The antonym of "horoscope" is not straightforward, as "horoscope" refers to a forecast based on astrological signs and celestial positions. However, one could consider "reality" as an antonym, since horoscopes deal with predictions and interpretations rather than concrete facts. Alternatively, terms like "science" or "reality check" might also serve as opposites, emphasizing empirical evidence over astrological beliefs.
