SpaceTime with Stuart Gary Gary - Series 29 Episode 10In this episode of SpaceTime, we explore groundbreaking developments in space exploration, including the imminent launch of the first nuclear-powered rocket, the merging of low mass dwarf galaxies, and the intriguing connection between Earth-like planets and gas giants.The Dawn of Nuclear Rocket TechnologyHistory is set to be made as NASA and DARPA prepare to test the world's first fully operational nuclear-powered orbital rocket. This innovative vehicle utilizes a nuclear thermal propulsion system that heats liquid hydrogen propellant through nuclear fusion, achieving nearly double the efficiency of conventional rockets. The test aims to validate reactor operation in orbit, potentially revolutionizing space travel by reducing transit times to Mars and allowing for larger payloads.Merging Dwarf Galaxies: A New DiscoveryA recent study published in the Astrophysical Journal Letters confirms that low mass dwarf galaxies can merge with one another. Observations of the Ursa Minor dwarf spheroidal galaxy reveal previously hidden stellar structures, suggesting that even the smallest galaxies experience mergers. These findings challenge traditional views on galaxy formation and evolution, indicating that interactions between dwarf galaxies may be more common than previously believed.The Connection Between Earth-Like and Gas Giant PlanetsAstronomers have found that rocky planets similar to Earth are more likely to exist in star systems that also contain large gas giants like Jupiter. This research, reported in Astronomy and Astrophysics, shows that cold Jupiters, which orbit beyond the snow line, play a significant role in the formation of super Earths in the inner regions of their planetary systems. The study offers new insights into the complex dynamics of planetary formation and the conditions that lead to the development of terrestrial planets.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journal LettersAstronomy and AstrophysicsScience AdvancesBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.(00:00:00) NASA and DARPA prepare to test the first nuclear-powered orbital rocket(00:10:15) New study confirms mergers among low mass dwarf galaxies(00:20:45) Link discovered between Earth-like planets and gas giants(00:30:00) China breaks through barriers in nuclear fusion reactor development(00:35:20) The impact of ultra-processed foods on global health.

SpaceTime with Stuart Gary Gary - Series 29 Episode 4In this episode of SpaceTime, we explore the latest revelations about supermassive black holes, the enigmatic interstellar comet 3I Atlas, and NASA's innovative tests on lunar surface interactions.Do All Galaxies Host Supermassive Black Holes?A groundbreaking study utilizing NASA's Chandra X-ray Observatory challenges the long-held belief that all galaxies harbor supermassive black holes at their centers. Analyzing data from over 1,600 galaxies, researchers discovered that only about 30% of dwarf galaxies contain these cosmic giants. The findings, published in the Astrophysical Journal, provide crucial insights into the formation of supermassive black holes and suggest that smaller galaxies may have significantly fewer black holes than their massive counterparts.No Evidence of Alien Intelligence from Comet 3I AtlasDespite sensational claims, a thorough investigation into the interstellar comet 3I Atlas has yielded no signs of extraterrestrial technology. Observations from the Green Bank Radio Telescope during the comet's closest approach revealed only radio frequency interference, dismissing earlier speculations of alien signals. The analysis reinforces the understanding that the comet's behavior aligns with natural phenomena, rather than advanced civilizations.NASA's Rocket Plume Studies on Lunar RegolithNASA is conducting new experiments to understand how rocket plumes interact with the lunar surface, crucial for future lunar landings. Using a sophisticated camera system, scientists are simulating rocket engine behavior in a vacuum chamber to analyze the impact of exhaust on lunar dust and rocks. The data collected will inform the design of landing systems for the Artemis missions and future Mars explorations, ensuring crew safety and mission success.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical JournalNASA ReportsJournal of Molecular and Cellular BiochemistryBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.(00:00:00) This is Space Time Series 29, Episode 4 for broadcast on 9 January 2026(00:00:47) Study reveals fewer supermassive black holes in smaller galaxies(00:12:30) No signs of alien technology from comet 3I Atlas(00:20:10) NASA's lunar regolith plume interaction tests(00:25:00) Science report: Microplastics and neurodegenerative diseases, dog ownership and community ties

In this episode, we dive into a myriad of exciting developments in the space industry and cosmology. We kick things off with a major shake-up as Blue Origin hires Tory Brian, the former president and CEO of United Launch Alliance, to lead their new national security group. This strategic move signals Blue Origin's serious intent to compete for lucrative national security launch contracts, especially with their upcoming Glenn Heavy Lift rocket. Next, we explore a new and intriguing theory regarding dark matter, proposing that it may be composed of giant, star-sized objects, referred to as exotic astrophysical dark objects (IADs). Researchers are optimistic about detecting these objects through gravitational lensing, potentially using data from the Gaia Space Telescope. Shifting our focus, we discuss the upcoming close encounter of Asteroid Apophis with Earth in 2029, where the European Space Agency and JAXA will collaborate on the Ramses mission to study the asteroid's behavior under Earth's gravity. Understanding these interactions is crucial for future planetary defense strategies. We also tackle the mystery of missing normal matter in the universe. A recent study utilizing fast radio bursts has confirmed that a significant portion of this matter resides in the cosmic web, providing a monumental victory for cosmology by completing the census of normal matter. As we move closer to home, we highlight a groundbreaking dataset released by researchers at Lawrence Livermore Laboratory, mapping one million stable trajectories in the cis-lunar space. This open-source resource will aid future lunar missions and infrastructure planning. Finally, we preview the astronomical events of 2026, including a total solar eclipse, a total lunar eclipse, and exciting meteor showers, all set against a backdrop of high solar activity promising stunning auroras.

SpaceX has revolutionised space travel, making reusable rockets a reality and dramatically reducing the cost of reaching orbit. But two high-profile Starship explosions have raised concerns about the company's approach to innovation and risk.Commercial spaceflight has rapidly expanded, with private companies looking to harness space resources and build new economies beyond Earth. Reusability has been a game-changer, significantly lowering launch costs and enabling more ambitious missions.SpaceX operates with a philosophy of rapid iteration, treating test failures as learning opportunities rather than setbacks. While this approach has led to major breakthroughs, repeated failures raise questions about long-term reliability and safety. Meanwhile, growing competition from other private space firms suggests the industry is no longer dominated by a single player.With rivals gaining ground and technological hurdles ahead, does SpaceX still have the edge in the new space economy?Contributors: Professor Michelle Hanlon, Executive Director of the Center for Air and Space Law at the University of Mississippi School of Law in the USAJack Burns, Professor Emeritus in the Department of Astrophysical and Planetary Sciences and Professor Emeritus in the Department of Physics in the USADr Ella Atkins is Fred D.

Episode 73: Astrophysical Prison Break   We're planning a prison break! But first, we're consulting the experts on this topic. Sabrina takes us to a distant galaxy cluster to figure out how so much light is escaping. Once we know how it's breaking free, Will brings us back a little closer to home where he consults with the Trojans (and we don't mean the ones from Homer's Odyssey) about how a fraction of their fellow soldiers made a successful getaway. As Kiersten comes along for the ride, she makes the terrible mistake of mentioning the dreaded space sound by name. Will we successfully escape? Or will we be caught and forced to listen to space sounds forever?   Astrobites: https://astrobites.org/2023/03/11/ https://astrobites.org/2020/05/13/   Space sound: https://youtu.be/BAWkuv1HXy4

Dr. Beatriz Villarroel is a researcher at the Nordic Institute for Theoretical Physics who is the brains behind the VASCO project - a study of Vanishing and Appearing Sources During a Century of Observation. The project asked a stunningly simple question - if we compare photographic plates of the cosmos taken in the 1950s with photographs taken in the last few years, would there be much of a difference? To their great surprise, Villarroel and colleagues discovered more than 100,000 mismatches between the two datasets. We talk to her about the missing objects, the art of astronomical observation, how to stay creative in a system that rewards incremental progress, and her ambitious goal of identifying and recovering an extraterrestrial object from within our solar system.

Can denoising diffusion probabilistic models generate realistic astrophysical fields? by Nayantara Mudur et al. on Thursday 24 November Score-based generative models have emerged as alternatives to generative adversarial networks (GANs) and normalizing flows for tasks involving learning and sampling from complex image distributions. In this work we investigate the ability of these models to generate fields in two astrophysical contexts: dark matter mass density fields from cosmological simulations and images of interstellar dust. We examine the fidelity of the sampled cosmological fields relative to the true fields using three different metrics, and identify potential issues to address. We demonstrate a proof-of-concept application of the model trained on dust in denoising dust images. To our knowledge, this is the first application of this class of models to the interstellar medium. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.12444v1

This meditation is to help you remove yourself from your human mind and connect deeper with your soul. In this meditation, you will find yourself in the soul realm. Here you will be guided to connect with the soul energy of a person who you feel that you have been holding a lot of emotional energy for. This means - if you have been waiting for someone to reach out, such as a friend, parents, interviewer, or client if you are a coach. This will allow you to release what you cannot control, and have a conversation, soul to soul, with that person to release the hold of your physical body and human mind. This is one of the most intimate and spiritual meditations I have ever wrote and shared. Thank you for opening yourself up to this space and the possibilities of this release. Once you complete this meditation, send me a message and let me know what you experienced. This meditation is a great one to come back to if you feel that you are holding energy that is not serving you with another person. You are in control of your own thoughts, emotions, and energy. Use this meditation to release the connection and take back your power while empowering the soul you connect with each time. --- Support this podcast: https://anchor.fm/jessbax/support

A crack in the track of the Hubble Constant by Marie Gueguen. on Tuesday 18 October Measuring the rate at which the universe expands at a given time -- the 'Hubble constant' -- has been a topic of controversy since the first measure of its expansion by Edwin Hubble in the 1920's. As early as the 1970's, Sandage et de Vaucouleurs have been arguing about the adequate methodology for such a measurement. Should astronomers focus only on their best indicators, e.g., the Cepheids, and improve the precision of this measurement based on a unique object to the best possible? Or should they 'spread the risks', i.e., multiply the indicators and methodologies before averaging over their results? Is a robust agreement across several uncertain measures, as is currently argued to defend the existence of a 'Hubble crisis' more telling than a single one percent precision measurement? This controversy, I argue, stems from a misconception of what managing the uncertainties associated with such experimental measurements require. Astrophysical measurements, such as the measure of the Hubble constant, require a methodology that permits both to reduce the known uncertainties and to track the unknown unknowns. Based on the lessons drawn from the so-called Hubble crisis, I sketch a methodological guide for identifying, quantifying and reducing uncertainties in astrophysical measurements, hoping that such a guide can not only help to re-frame the current Hubble tension, but serve as a starting point for future fruitful discussions between astrophysicists, astronomers and philosophers. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.09661v1

The PhotoDissociation Region Toolbox: Software and Models for Astrophysical Analysis by Marc W. Pound et al. on Monday 17 October The PhotoDissociation Region Toolbox provides comprehensive, easy-to-use, public software tools and models that enable an understanding of the interaction of the light of young, luminous, massive stars with the gas and dust in the Milky Way and in other galaxies. It consists of an open-source Python toolkit and photodissociation region models for analysis of infrared and millimeter/submillimeter line and continuum observations obtained by ground-based and sub-orbital telescopes, and astrophysics space missions. Photodissociation regions (PDRs) include all of the neutral gas in the ISM where far-ultraviolet photons dominate the chemistry and/or heating. In regions of massive star formation, PDRs are created at the boundaries between the H II regions and neutral molecular cloud, as photons with energies 6 eV $ < h nu < $ 13.6 eV photodissociate molecules and photoionize metals. The gas is heated by photo-electrons from small grains and large molecules and cools mostly through far-infrared fine-structure lines like [O I] and [C II]. The models are created from state-of-the art PDR codes that includes molecular freeze-out; recent collision, chemical, and photo rates; new chemical pathways, such as for oxygen chemistry; and allow for both clumpy and uniform media. The models predict the emergent intensities of many spectral lines and FIR continuum. The tools find the best-fit models to the observations and provide insights into the physical conditions and chemical makeup of the gas and dust. The PDR Toolbox enables novel analysis of data from telescopes such as ISO, Spitzer, Herschel, STO, SOFIA, SWAS, APEX, ALMA, and JWST. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.08062v1

Constraints on extended Bekenstein models from cosmological, astrophysical, and local data by Léo Vacher et al. on Wednesday 12 October Searching for variations of nature's fundamental constants is a crucial step in our quest to go beyond our current standard model of fundamental physics. If they exist, such variations will be very likely driven by the existence of a new fundamental field. The Bekenstein model and its extensions introduce such a scalar field in a purely phenomenological way, inducing a variation of the fine-structure constant on cosmological scales. This theoretical framework is as simple and general as possible while still preserving all the symmetries of standard quantum electrodynamics. When allowing for couplings to the other sectors of the Universe, such as baryons, dark matter, and the cosmological constant, the Bekenstein model is expected to reproduce the low energy limits of several grand unification, quantum gravity, and higher dimensional theories. In this work, we constrain different versions of the Bekenstein model by confronting the full cosmological evolution of the field with an extensive set of astrophysical, cosmological, and local measurements. We show that couplings of the order of parts per million (ppm) are excluded for all the cases considered, imposing strong restrictions on theoretical frameworks aiming to deal with variations of the fine-structure constant. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2207.03258v2

Testing the mean field theory of scalar field dark matter by Andrew Eberhardt et al. on Wednesday 12 October Scalar field dark matter offers an interesting alternative to the traditional WIMP dark matter picture. Astrophysical and cosmological simulations are useful to constraining the mass of the dark matter particle in this model. This is particularly true at low mass where the wavelike nature of the dark matter particle manifests on astrophysical scales. These simulations typical use a classical field approximation. In this work, we look at extending these simulations to include quantum corrections. We look into both the ways in which large corrections impact the predictions of scalar field dark matter, and the timescales on which these corrections grow large. Corrections tend to lessen density fluctuations and increase the effect of "quantum pressure". During collapse, these corrections grow exponentially, quantum corrections would become important in about ~30 dynamical times. This implies that the predictions of classical field simulations may differ from those with quantum corrections for systems with short dynamical times. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.05842v1

GWSim: A python package to create GW mock samples for different astrophysical populations and cosmological models of binary black holes by Christos Karathanasis et al. on Wednesday 12 October Precision cosmology with gravitational wave (GW) sources requires understanding the interplay between GW source population and cosmological parameters governing the dynamics of the Universe. With the fast increase of GW detections, for exploring many aspects of cosmology and fundamental physics it is necessary to develop a tool which can simulate GW mock samples for several population and cosmological models with and without a galaxy catalog. We have developed a new code called GWSim, allowing to make GW mock events from a large range of configurations, varying the cosmology, the merger rate, and the GW source parameters (mass and spin distributions in particular), for a given network of GW detectors. We restrict the cosmology to spatially flat universes, including models with varying dark energy equation of state. GWSim provides each mock event with a position in the sky and a redshift; these values can be those of random host galaxies coming from an isotropic and homogeneous simulated Universe or a user-supplied galaxy catalog. We use realistic detector configurations of the LIGO and Virgo network of detectors to show the performance of this code for the latest observation runs and the upcoming observation run. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.05724v1

Samuil Kaplan and the development of astrophysical research at the Lviv University dedicated to the 100th anniversary of his birth by Bohdan Novosyadlyj et al. on Tuesday 20 September Samuil Kaplan (1921-1978) was a productive and famous astrophysicist. He was affiliated with a number of scientific centers in different cities of former Soviet Union. The earliest 13 years of his career, namely in the 1948-1961 years, he worked in Lviv University in Ukraine (then it was called the Ukrainian Soviet Socialist Republic). In the present paper, the Lviv period of his life and scientific activity is described on the basis of archival materials and his published studies. Kaplan arrived in Lviv in June 1948, at the same month when he obtained the degree of Candidate of science. He was a head of the astrophysics sector at the Astronomical Observatory of the University, was a professor of department for theoretical physics as well as the founder and head of a station for optical observations of artificial satellites of Earth. He was active in the organization of the astronomical observational site outside of the city. During the years in Lviv, Kaplan wrote more than 80 articles and 3 monographs in 9 areas. The focus of his interests at that time was on stability of circular orbits in the Schwarzschild field, on white dwarf theory, on space gas dynamics, and cosmic plasma physics, and turbulence, on acceleration of cosmic rays, on physics of interstellar medium, on physics and evolution of stars, on cosmology and gravitation, and on optical observations of Earth artificial satellites. Some of his results are fundamental for development of theory in these fields as well as of observational techniques. The complete bibliography of his works published during the Lviv period is presented. Respective scientific achievements of Samuil Kaplan are reviewed in the light of the current state of research in these areas. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.09494v1

David Grinspoon is an astrobiologist, an award-winning science communicator, and a prize-winning author of books including Earth in Human Hands, Lonely Planets, and Chasing New Horizons. He works as a scientist at the Planetary Science Institute and an Adjunct Professor of Astrophysical and Planetary Science at the University of Colorado. He was appointed as the inaugural Chair of Astrobiology at the U.S. Library of Congress and has been involved with interplanetary missions for NASA, the Japanese Space Agency, and the European Space Agency.David joins me today to discuss planet changing and the need to see ourselves as a planetary force. He shares why we need the humility to realize that we don't know enough and why we should encourage more insight. He shares what the Anthropocene era is and how humanity has become the first self-aware geological process. We discuss hidden, long-term threats such as climate change and pandemics. David shares how past human activity resulted in unintended consequences of planetary change and how intentional intervention, such as the coordinated global response and transnational cooperation to stop damage to the ozone layer, demonstrates how we can win the race between education, action, and catastrophe. We also discuss whether we know enough to build a self-sustaining habitat on Mars and the values we will need to take.“We need to recognise ourselves as a planetary force and fold that knowledge into our responses.” - David GrinspoonThis week on Insert:Human●      What astrobiology is and how it brings science and philosophy together●      How we can use astrobiology as a tool to look at our planet and situation●      The Anthropocene era and humanity's geological effect on the planet●      The most pressing long-term threats that are almost invisible and the risks of not acting now●      Why we need to recognize that we are a planetary force to make intentional change●      The need for global governance and coordinated responses●      How international scientific cooperation is a model for common goals transcending local affiliations●      The scientific and social challenges of planet colonization●      Thriving versus surviving and how we measure successResources Mentioned:●      Our World in DataConnect with David Grinspoon:●      David Grinspoon's website●      Earth in Human Hands by David Grinspoon●      Chasing New Horizons by David Grinspoon●      Lonely Planets by David Grinspoon●      David Grinspoon on LinkedInInsert:Human - For a Better Life & Better WorldThanks for tuning into this week's episode of Insert:Human.

Astrophysical fluid dynamics is a modern branch of astronomy involving fluid mechanics which deals with the motion of fluids, like the gases which the stars are made up of or any fluid which is found in outer space.

Another one from the Taco Bell Quarterly rejections file. Admittedly, reading it again and knowing TBQ's voice, this wasn't a great fit, but I still think it's a fun little piece of absurdism that I'd like to share with you. A couple more of these to go before I likely go dark again, unless I start selling a lot of poetry books and y'all demand that I carry on (https://lefthandrob.net is where you can find the links to the goods).

2022 is a big year for space science. NASA has two major missions underway. The first – DART (Double Asteroid Redirection Test) – will test the agency's ability to defend Earth against asteroids. The second – the James Webb Space Telescope (the successor to Hubble) – will be used to study the origins of the universe and search for possible life in the universe beyond Earth. We talked about these missions with Nancy Chabot, Planetary Chief Scientist at Johns Hopkins University's Applied Physics Laboratory and Coordination Lead on the DART mission, and Meredith MacGregor, assistant professor of Astrophysical and Planetary Sciences at the University of Colorado Boulder.

This week, we present two stories about respect in science — how we get it and how we keep it.Part 1: Meisa Salaita's brand-new PhD in chemistry isn't much help as she prepares to teach ninth-grade physics.Part 2: Early in her career, astronomer Jackie Faherty's work is stunned when a senior researcher eviscerates her work at a conference.Meisa Salaita has made it her mission to help others see and appreciate the beauty of science by making it a part of everyday cultural experiences. Through her work founding and directing the non-profit Science ATL, she spends her days bringing people together through the wonder of science by creating public science events like the Atlanta Science Festival. Meisa also writes, has produced radio stories, and hosted TV shows — all in the name of science. In addition to her work with Science ATL, Meisa is a producer for The Story Collider, a science storytelling podcast. Meisa has a Ph.D. in chemistry from Northwestern, and has been named by the Atlanta Business Chronicle as one of their "Women Who Mean Business" and by Atlanta Magazine as one of their "Women Making a Mark".Jackie Faherty is a senior scientist and senior education manager at the American Museum of Natural History (AMNH). Her research group entitled “Brown Dwarfs in New York City (BDNYC)” is at the forefront of low mass star, brown dwarf and giant exoplanet characterization studies. She is also co-founder of the successful citizen science project called “Backyard Worlds: Planet 9” which has involved over 150,000 volunteers in searches for previously missed cold components of the nearby solar neighborhood. Dr. Faherty has over 100 peer-reviewed papers in Astrophysical journals and has won numerous awards or grants from private and national foundations such as NASA and the NSF. She is also a regular science communicator having consulted on stories that ran in the NY Times, the Wall Street journal, NPR, and on national television. In her position at AMNH, Faherty strives to create more opportunities for underrepresented minorities to enter STEM through unique outreach endeavors.  Learn more about your ad choices.

Out of all the conspiracy theories we've done, this is by far the best one. Consider that the world as we knew it ended in 2012; it's plausible. We're 8+ years from the end times the Mayans predicted of December 21, 2012, and if you told 2012 you some of things that have happened since then...would you believe yourself? Like, really? I don't think I could.In this episode we discuss five great theories:Astrophysical phenomena caused the end times.The discovery of the Higgs Boson, or God Particle, by CERN led to the end of our universe as we know it.There was a reality changing event.2012 was the end of history as we know itAnd the god damn Mayans were right all along.Matt and I go in-depth on all of these, which definitely left me with the Larry David face of, well....eh...it could happen.

On this edition of the Seven Ages Audio Journal, after news pertaining to the surprising results of DNA studies in West Africa and a Japanese experiment in search of answers about ancient seafaring, we turn our attention to one of the greatest controversies in modern science that unites the fields of archaeology, geology, and climate science: the Younger Dryas impact hypothesis. Joining us to discuss it are two leading experts on the topic--a geoarchaeologist and a planetary scientist--who offer their perspectives on the latest developments in support of this hotly debated theory. Christopher R. Moore, PhD, is a geoarchaeologist and Special Projects Director with the Savannah River Archaeological Research Program. His research interests include site formation processes and geochronology of stratified sites in the southeastern Coastal Plain, paleoenvironmental reconstruction, early hunter-gatherer adaptations, lithic technology, and immunological blood residue analysis of stone tools. Chris is also the lead researcher of the White Pond Human Paleoecology Project and has authored and coauthored numerous papers on the Younger Dryas Impact Hypothesis including one documenting the presence of widespread Platinum anomalies at the Younger Dryas Boundary (YDB) as well as a recent paper on White Pond (near Elgin, SC) supporting the YD impact hypothesis. Malcolm Lecompte is a planetary scientist and remote sensing specialist. He holds a B.S. with Honors in Physics from the University of Wyoming and an MS in Astro-geophysics from the University of Colorado in Boulder. He received his Ph.D. in Astrophysical, Planetary and Atmospheric Sciences in 1984. Lecompte also became affiliated with the Naval Aviation reserve in 1980, and before ending his military flight career in 1991, compiled over 1,000 hours of military aircrew and private pilot time, officially retiring from the Naval Reserve as a Commander in 1998 after 23 years of active service. From 2004 until 2009, after a post-doctoral appointment at the Harvard College Observatory and Smithsonian Center Astrophysics (as well as a period managing DoD sponsored R&D projects), Lecompte held a faculty position as an Associate Professor and Research Director at Elizabeth City State University's Center of Excellence in Remote Sensing Education and Research. Now retired, LeCompte has since devoted himself to investigating earth impacts during the late Pleistocene and Holocene epochs by asteroid and comets. He is currently working in collaboration with colleagues at ECSU and other research organizations.

Ken Ham deletes my comments and questions about his discussion of atheists in a live video and myself being the atheist I am had some rebuttals. Too much for good ole Ham. Kenneth Alfred Ham (born 20 October 1951) is an Australian-born Christian fundamentalist, young Earth creationist and apologist living in the United States. He is the president of Answers in Genesis (AiG), a creationist apologetics organization that operates the Creation Museum and the Ark Encounter. Ham advocates biblical literalism, believing that the Book of Genesis is historical fact and the universe is approximately 6,000 years old,[n 1] contrary to multiple individual lines of scientific evidence which show the Earth is about 4.5 billion years old and the universe is about 13.8 billion years old.[2][3] According to Ham, he was inspired by his father, also a young Earth creationist, to interpret the Book of Genesis as "literal history" and first rejected what he termed "molecules-to-man evolution" during high school.[5] As a young Earth creationist and biblical inerrantist, Ham believes that the Book of Genesis is historical fact. Ham believes the age of the Universe to be about 6,000 years[n 1] and asserts that Noah's flood occurred about 4,400 years ago in approximately 2348 BC.[41] (Astrophysical measurements and radiometric dating show that the age of the universe is about 13.8 billion years and the age of the Earth is about 4.5 billion years.)[2] Arguing that knowledge of evolution and the
