We welcomed Dr. Duncan Farrah to the program to discuss his recent paper, "Observational Evidence for Cosmological Coupling of Black Holes and its Implications for an Astrophysical Source of Dark Energy." His paper has been posted in the comments section of the blog for this show. I do urge you to download and read it or at least have it available as a reference while listening to the program. In addition, an excellent short summary of the paper, "Dark energy from supermassive black holes? Physicists spar over radical idea" can be found at https://sciencesprings.wordpress.com/2023/03/07/from-science-magazine-dark-energy-from-supermassive-black-holes-physicists-spar-over-radical-idea. I believe you should definitely read this paper in advance of listening to Dr. Farrah.
As you might imagine, much of our discussion was highly technical and for those without a physics background, probably more than just a little highly technical! Because of this, I again urge you to read the paper and the article. Also, use the Tags as a guide to most of our discussion topics along with the order discussed but in truth, the tags barely touch the surface of what we talked about with our guest. For your convenience, here are the tags being used for this programs:
Dr. Duncan Farrah, Observational Evidence for Cosmological Coupling of Black Holes and its Implications for an Astrophysical Source of Dark Energy, dark energy, Black Holes, elliptical galaxies, impact on everyday life, relativity, vacuum energy of empty space, Black Holes source of vacuum energy, the number of black holes, Dr. Becky of Oxford, disc galaxy, spiral galaxy, avoiding bias, galaxy mergers, event horizons, the Kerr Solution, Kerr Black Holes, dark matter, physics explains the natural world, laws of conservation, symmetry, Schwarzschild radius, gravitational radius, singularity, Super Massive Black Hole growth in elliptical galaxies, supermassive black holes are the source of dark energy, The Scientific Method, science protocols, learning science.
One part of the show that I appreciated pertained to the critique of his work by the Oxford physicist, Dr. Becky. As he explained the differences Dr. Becky stated with his paper plus the endless amount of detail with black holes, I asked Duncan how it came to be that physicists and scientists, regardless of their education, experience and special interests, all seem to speak the same language with each other. In addition, I asked him where and how he learned all the details including the minutia he referenced regarding galaxies, black holes and dark energy, dark matter, relativity, and so much more. This started a most interesting discussion about the scientific method, how scientists learn and study and talk with one another despite their background and educational differences. This turned into an important subtopic for the show. If this interests you or you have ever been curious about some of these questions, do pay attention to this part of our program. Also, post your thoughts and comments about it on our blog.
As for the rest of the program, the best way for me to summarize it is with the key words which I have provided. The tags or key words supplement the source material which includes his paper and a quality summary article of the paper and his work.
Please post your comments/questions for Dr. Farrah on our blog. If you want to reach him at the University of Hawaii, you can do so through his faculty website or through me.
