Space Nuts Episode 505: Black Holes, TRAPPIST Planets, and Cosmic Fluctuations
In this engaging Q&A edition of Space Nuts, host Andrew Dunkley and astronomer Professor Fred Watson tackle a variety of listener questions that delve deep into the mysteries of the universe. From the nature of black holes and their gravitational effects to the intriguing dynamics of the TRAPPIST system, this episode is packed with thought-provoking discussions and cosmic insights that will keep you captivated.
Episode Highlights:
- Black Hole Mysteries: Andrew and Fred explore whether objects entering a black hole, such as electrons or grains of sand, can be accelerated beyond the speed of light. They clarify the laws of physics that remain intact even within the event horizon and the implications of mass changes.
- TRAPPIST System Insights: The duo discusses the absence of gas giants in the TRAPPIST system and the possible reasons behind this phenomenon, including the formation processes and the potential for undiscovered planets.
- Star Collisions: Lloyd from Cairns asks whether everyday stars like our sun ever collide, leading to a discussion about the rarity of such events compared to black hole and neutron star collisions, especially during galaxy mergers.
- Early Universe Fluctuations: Mark from Louisiana poses a thoughtful question about the energy density fluctuations observed in the WMAP image of the early universe, prompting a conversation about quantum fluctuations and their role in cosmic structure formation.
