Special Guest: Dr. Grant Vezina. Do the stars influence our lives? Is there any scientific basis to astrology? In this episode, Aya and Josh are joined by longtime friend Grant Vezina as they chat about high school and delve into the origins of — and differences between — astronomy and astrology, exploring the dichotomy between science and pseudoscience, horoscopes, the PT Barnum Effect, the precession of the equinoxes, orbital changes and paleoclimatology, comparing the scientific basis (or lack thereof) of astrology to the rigor of astronomy and the scientific method, while also touching on the potential for relativistic speeds and interstellar travel, the vastness of the universe, and the power of science fiction to inspire and predict the future.
