In this episode I’m digging into a recent announcement from the astronomy community. The Gaia satellite has been making high precision measurements of the position and velocity of billions of nearby stars. Researchers have used this data to test the theory of gravity, and more specifically Modified Newtonian Dynamics or MOND. This theory was developed to explain away the need for dark matter. Dark matter was originally postulated to account for the anomalous rotation curves of all galaxies. Basically, if you use their surface brightness as a proxy for their matter distribution you would expect the outer regions of the galaxy to be moving slower than they seem to be. MOND suggests that gravitational acceleration stops dropping off as fast when the acceleration drops below a particular threshold value. Researchers analyzed the rotation curves of 10s of thousands of widely separated binary stars in the Gaia dataset and they believe that the data support MOND over Newton, and their results seem to provide a high degree of confidence. The press coverage seems to suggest that this is a smoking gun that decisively overthrows Newtonian gravity and General Relativity all at once. If this is true it is huge news. Why are the authors not packing their bags to Sweden as we speak? With a little digging, I’ve found that other researchers looking at the same Gaia dataset have come to the opposite conclusion that the data supports General Relativity over MOND. What gives? To understand this discrepancy I’m interviewing a skeptical astronomer, Dr. Indranil Banik. Dr Indranil Banik did his undergraduate at Trinity College, Cambridge before moving to Saint Andrews for his PhD with Hongsheng Zhao, where they worked together on Milgromian dynamics (MOND). Dr Banik then went to Bonn for a Humboldt fellowship with Pavel Kroupa. He returned to Saint Andrews in 2021 and spent his first year back on a detailed 150 page invited review on all aspects of MOND. He has been working on the wide binary test since late 2017. He organised the fortieth anniversary celebration of MOND conference in Saint Andrews in summer 2023. Among other results presented here, conflicting results were presented on the wide binary test and there was intense controversy surrounding whether the results indicate a failure of Newtonian gravity at low accelerations.

Famous philosopher Bertrand Russell joins Dr. Al Scott to explore determinism, free will, and their connections to physics, neuroscience, and AI. They discuss the illusion of free will, the mechanistic nature of the universe, and the implications for consciousness and decision-making. They also delve into quantum mechanics and its role in the debate on moral responsibility. Join the conversation and support the podcast!

Have you heard the news? The Fukushima Daiichi nuclear plant is dumping radioactive waste into the Pacific ocean! Is this a travesty or is it a manufactured controversy? The operator of the Fukushima Daiichi nuclear power plant in Japan is planning to dump over 1 million tonnes of radioactive wastewater in the ocean. Environmental groups around the world are outraged. Protesters line the streets in Korea. Chinese governments are boycotting Japanese products. Headlines scream about radioactive fish. What’s going on? It’s time for a Rational View.

In this episode I want to investigate claims in the news of an insect Armageddon. Specifically it has been reported that insect populations around the globe have plummeted by up to 75% in recent years. As anecdotal evidence of this old timers like myself use the car windshield as a gauge.  Back in the day, any summer drive would end up with your windshield plastered with insect carcasses. These days they are often pristine. Are we witnessing the ecological collapse prophesied by climate scientists? Insects are important to ecosystems and their disappearance would have huge impacts in terms of pollinators, and food chains. Is this real, is it global, and what is causing it? Maybe this is a good thing if mosquito populations are dropping. In terms of a potential tipping point where the loss of insects causes whole ecosystems to collapse, the honest answer is we just don’t know when the point of no return is.

In this episode I answer the question, 'Who is misinforming the public about nuclear energy and why?'. I touch on the influence of the oil industry on anti-nuclear disinformation, and I explore the origins of the anti-nuclear protest movement.

Dr. Michael Shermer, a college professor and definitive skeptic, discusses scientific experiments influenced by social factors, the challenges of defining intelligence and success, replication crisis in social sciences, belief in paranormal phenomena, competition and cooperation in science and society, and a casual conversation about Scooby-Doo and Neil deGrasse Tyson

In this episode I want to follow up on last week’s podcast regarding the announcement of the discovery of a room temperature ambient pressure superconductor, how scientists addressed the claim, and compare it with the cold fusion announcement and ongoing scientific controversy from the 1980’s.

In this episode I provide a round-up review of current events in science, and the popular controversies surrounding these issues. The recent announcement of room temperature superconductivity promises to be the biggest scientific breakthrough of the century if verified. We should know in days if it is true. The US congress heard testimony that UFOs are actually aliens visiting us from other worlds. There has been a recent surge of interest in the possibility that COVID-19 was caused by a lab leak in the Wuhan institute of virology. In addition to all of this, surface temperatures in the North Atlantic ocean are hotter than we've ever seen at this time of year. What should we take from all of this?

This episode is a special treat and a bit of a throwback to when I achieved one of my podcast goals. In honour of The Rational View blowing past 100,000 downloads this month, this is a re-release of my interview from almost two years ago with the famous Dr. Neil deGrasse Tyson, director of the Hayden Planetarium. I hope you can sit back and relax and enjoy it with me. Thank you for supporting the podcast! Famed astrophysicist Dr. Neil deGrasse Tyson was named the Sexiest Astrophysicist alive in 2000 by People magazine. Selected as one of the 100 most influential persons in the world by Time magazine in 2007, Dr. Tyson was awarded the Stephen Hawking Medal for Science Communication in 2017.

In this episode I have an interview with a leading scientist specializing in gut microbiota. These are the microbes that live in your intestine and help you digest your food. Our DNA does not have all the enzymes we need to break down food into the vitamins and minerals we need. We live in a symbiotic relationship with this microbial ecosystem.  We provide the microbes a home and they provide us with nutrients. When the ecosystem gets out of whack we can get sick. Sometimes we take anti-biotics to cure an infection and that throws a huge wrench into this ecosystem. I’ve seen a lot of folks saying probiotics help to build a robust microbiome, and I’ve also heard a lot of folks saying that anything you eat gets killed in the stomach. I’d like to hear what the experts have to say. Professor Jack Gilbert joined UCSD in 2019 where he is a Professor in Pediatrics and the Scripps Institution of Oceanography, Associate Vice Chancellor for Marine Science, and Director of both the Microbiome and Metagenomics Center and the Microbiome Core Facility. He uses molecular analysis to test fundamental hypotheses in microbial ecology. He cofounded the Earth Microbiome Project and American Gut Project, has authored over 400 peer reviewed publications and book chapters on microbial ecology, co-authored the book “Dirt is Good,” and is the founding Editor in Chief of ASM mSystems journal. He founded BiomeSense Inc to produce automated microbiome sensors.
