    Join Andrew Dunkley and Professor Fred Watson in this captivating Q&A episode of Space Nuts, where they explore the cosmic questions posed by our curious audience. From the mysteries of a universe without black holes to the peculiar atmosphere of Saturn's moon Titan, this episode is brimming with fascinating insights and astronomical discussions.
    Episode Highlights:
    - Universe Without Dark Matter and Energy: Delve into the possibilities of a universe devoid of dark matter, dark energy, and black holes. Explore the implications for galaxy formation and the cosmic web, and ponder the nature of dark energy's role in the universe's expansion.
    - Energy Loss and the Universe's Age: Investigate the concept of energy loss in the universe and the methods used to calculate its age. Discover why uranium's half-life isn't the key to unlocking the universe's timeline and how the Hubble constant plays a role.
    - Early Universe Surprises: Question the surprises of finding ancient cosmic structures in the early universe. Examine how galaxy formation models are continually refined and the potential revelations from the Square Kilometre Array.
    - Titan's Unique Atmosphere: Unravel the mystery of Titan's dense atmosphere and compare it to Mars' inability to retain one. Consider the possible factors contributing to Titan's atmospheric retention and the role of cryovolcanism.
