Special Guest: Dr. Grant Vezina. How big is the universe? How have key astronomical discoveries fleshed out our understanding of Earth and the universe beyond? In this episode, Aya and Josh further explore the mysteries of the cosmos with Dr. Vezina, including the faint young sun paradox, the great oxidation event, global ice ages, climate feedback loops, mass extinctions and the resilience of life, infrared astronomy, the James Webb vs. Hubble space telescopes, Stargate vs. Futurama, the size and topology of the universe, the expansion of space, the cosmological event horizon, time dilation and black holes, delving deeper into mind-bending sci-fi concepts like FTL travel, wormholes, warp drives, negative mass, dark matter, and manipulation of spacetime, while also touching on the potential merits of astrology (e.g., oracle cards), comparing Western and Eastern astrological practices, and assessing their comfort and entertainment value.
