An all-listener questions episode. Hear what's on the minds of our
listeners. Explore the mysterious universe and uncover the secrets
of dark matter and dark energy with Andrew and Fred. "Matter
tells space how to bend. Space tells matter how to move." - John
Wheeler Professor Fred Watson is an astronomer and science
communicator, best known for his work in the field of astrophysics.
He is a regular contributor to numerous science-related media
outlets around the globe. Professor Fred Watson was taken aback by
Rusty's question about how the rotation curves vary with
wavelength. After exploring Einstein's famous theory of gravity,
Fred discussed the dangers of the neutron star and the web of dark
matter that formed structures in the universe. He explained that
dark energy, while being uniform throughout the universe, was the
cause of the universe's accelerating expansion. He then discussed
the possibility of dark matter black holes, concluding that they
should behave the same as normal matter black holes. Finally, he
discussed the research done by colleagues in Australia which
suggested that the speed of light may have been different in the
past. This thought-provoking conversation left Fred and the
listeners with questions to ponder. In this episode, you will learn
the following: 1. What phenomena would you encounter if you were
magically transported to a neutron star? 2. What is the difference
between dark matter and dark energy and how do they interact with
each other? 3. Could the speed of light or charge of the electron
have been different in the past? Resources: For more Space Nuts and
