Space Nuts Q&A: Background Modulation, Energy into Matter, and Spacecraft in Space

Join Andrew Dunkley and Professor Fred Watson in this intriguing Q&A episode of Space Nuts, where they delve into listener questions about the mysteries of space and the universe.Episode Highlights:

- Background Modulation: Craig from Maroombula, NSW, asks about the effects of background gravitational modulation on the cosmic microwave background. Fred explains the relationship between gravitational waves and the cosmic microwave background, and whether these modulations could influence our observations.

- - Energy into Matter: John inquires about the possibility of turning energy into matter in a lab setting. Fred discusses a groundbreaking experiment at Brookhaven National Laboratory that successfully demonstrated this phenomenon.

- - Spin Rates in Space: John also asks why the Earth spins at a constant speed and whether all celestial bodies spin at constant rates. Fred provides insights into the physics of spin and the factors that influence it.

- - Spacecraft in Space: Nigel from Brisbane wonders if two spacecraft meeting in interstellar space would stay perfectly still or drift apart. Fred explains the concept of station keeping and the factors that could cause spacecraft to drift.
