Supercharged Neutrinos, Exploding Black Holes & Lunar Mysteries Uncovered | Q&A
5/18/202659 min
Exploding Black Holes, Lunar Mysteries, and Cosmic Questions In this enlightening Q&A edition of Space Nuts, hosts Andrew Dunkley and Professor Jonti Horner tackle an array of fascinating questions from listeners. From the enigmatic nature of supercharged neutrinos linked to black holes to the mysteries of the Moon's surface, this episode is a deep dive into the cosmos.
Episode Highlights:
- Supercharged Neutrinos and Black Holes: Nick's intriguing question about the detection of a supercharged neutrino prompts a discussion on the theoretical concept of exploding black holes and Hawking radiation. Jonti explains the complexities of black hole evaporation and the potential implications for our understanding of the universe.
- The Dark Side of the Moon: Andrew returns with her questions about the far side of the Moon, exploring why it appears less damaged than the near side. Jonti provides insights into the Moon’s geological history and the differences in surface features that contribute to this phenomenon.
- Shallow Craters on the Moon: Continuing with Andrew's inquiries, the hosts discuss the nature of lunar craters and why many appear shallower than expected. Jonti elaborates on the processes that lead to complex craters and their unique characteristics compared to simpler ones.
- Planet Formation and Solar System Dynamics: Eli's two-part question leads to a discussion about the composition of planets in our solar system and how their formation relates to the elements present in the Sun. The hosts delve into the nuances of planetary formation and the role of distance from the Sun in determining a planet's composition.
- Speed of the Solar System: Eli's second question prompts an exploration of how fast our solar system could travel without causing noticeable effects on Earth. Jonti explains the implications of high speeds in a dense stellar environment and how it might alter our cosmic perspective.

[ship horn] Hi there. Thanks for joining us on a Q&A edition of Space Nuts. Andrew Dunkley here, your host. Great to have your company. Coming up, we've got a few questions. Nick is going to ask about supercharged neutrinos. Andrea is making a return appearance. She's got a couple of questions about the dark side of the moon and shallow craters, and Eli is asking about elements and the speed of objects. And if we've got time, we'll chuck another question into the mix as well. All coming up on this edition of Space Nuts.

And with Fred away, Jonti can play. It's, uh, Professor Jonti Horner, Professor of Astrophysics at the University of Southern Queensland. Jonti, hello again.
Jonti Horner· Guest1:18
Good afternoon. How are you going?
Andrew Dunkley· Host1:19
I'm well. Great to see you. I think we should just go straight into it and, uh, hit you with our first question. It's a, it's a topic I'm not overly familiar
