In this engaging Q&A episode of Space Nuts, join Andrew Dunkley
and Professor Fred Watson as they tackle a variety of intriguing
questions from listeners. From the mysteries of redshift and the
perplexing concept of dark photons to the vastness of deep space
astronomy and the ongoing expansion of the universe, this episode
is brimming with thought-provoking insights and scientific
discussion.

In this episode:

- Understanding redshift: What does it mean for the energy of light
from distant galaxies, and how does it relate to the universe's
expansion?

- A deep dive into dark photons: What are they, and how might they
help explain dark matter and dark energy?

- Clarifying deep space astronomy: Why do we observe light from
distant galaxies as it was billions of years ago, and how does this
relate to our understanding of cosmic history?

- Exploring the universe's expansion: What is it expanding into,
and what shapes might it take?

- The implications of cosmic observations for our understanding of
the universe's structure and evolution.

(00:00) This is a Q and A edition of Space Nuts

(01:14) Question from Roger: Does red shift of galaxies contribute
to universe expansion

(07:53) Roger Stern: Well, generally speaking, you do get
alternative views on this

(08:33) Fred Watson uses term dark photon to describe hypothetical
dark particles

(13:29) Fred: I still can't get my head around deep space
astronomy

(22:03) If the universe is expanding, what is it expanding
into
