Space Nuts Q&A: Gravity Without Mass, Energy and Gravity, and
Early GalaxiesJoin Andrew Dunkley and Professor Fred Watson in this
engaging Q&A episode of Space Nuts, where they tackle
intriguing questions from our listeners about gravity, energy, and
the movement of galaxies.

Episode Highlights:

Gravity Without Mass? Steve from New Zealand asks if gravity
can exist without mass. Fred dives into the complexities of this
question, exploring the relationship between energy and mass, and
whether this could offer an alternative explanation for dark
matter.

- Energy and Gravity: Gus from Issaquah, Washington, ponders
whether energy creates gravity and if a gravitational field
itself generates energy and mass. Fred discusses the potential
implications and the concept of gravitational energy.

- Early Galaxies Moving Towards Us: Nick from Auckland, New
Zealand, wonders if early galaxies could be moving towards us,
currently out of reach. Fred explains the mechanics of galaxy
movements and the Doppler effect, shedding light on whether such
galaxies could be hidden from view.
