Most egregious Flat Earth claim – Gravity is simply buoyancy & density – Debunked

I am a Christian Universalist, All will ultimately be saved through Jesus Christ (1 Cor 15:22), a retired NASA engineer, a student of conspiracy theories, and started blogging in 2017 initially due to concern about the emergence of the flat earth movement, within which many Biblical literalists claim the earth is actually flat and that this truth has been hidden by Satan and science and NASA in the greatest of all conspiracies to keep people from the truth of God. I have ended up blogging on a variety of topics since then. In May 2020 I had the privilege and honor of being a reviewer of the English version of the book “The Ground Zero Model” by physicists Heinz Pommer and Colleagues. On the occasion of writing my review of the book, I updated my bio which is given below. T. Mark Hightower has both B.S. & M.S. degrees in chemical engineering from San Jose State University. He initially worked in the chemical industry and then worked for NASA for 25 years as a federal government employee, where he took an oath to support and defend the Constitution of the United States against all enemies, foreign and domestic. He retired from NASA in 2015. His work at NASA included space life support systems for future long duration missions, hazardous materials management, arc jet testing of heat shield materials for spacecraft entry into planetary atmospheres, hyper velocity free flight aerodynamic testing of spacecraft and aircraft models in enclosed terrestrial ballistic range, facility water management including drinking water, storm water, industrial waste water, water conservation and reclamation, pollution prevention, above ground storage tanks, and climate change risk management. While at NASA he also served in the Ames Federal Employees Union as secretary, deputy chief steward, and vice president for safety. He became a born again student of conspiracy theories in January 2004 after stumbling upon Peter Meyer's Serendipity web site and learning that controlled demolition was a more likely explanation for the destruction of the Twin Towers than the official government story. Based on further research and conversations with fellow employees with extensive explosives expertise, it did not take long for him to see that the evidence pointed very strongly to 9/11 having been a neocon false flag operation designed to falsely blame Muslims for something they did not do in order to ignite the “war on terror” against them for the benefit of Israel. Ever since then he has been working hard with many others to obtain true justice in the exposure apprehension conviction and punishment of the many real perpetrators who have so far eluded justice. He has said, “The blood of many thousands if not millions in the world who have lost their lives and suffered horribly because of their traitorous schemes cries out for them to be brought to justice and severely punished.” In 2010 he became concerned when consulting with some retired military veterans with explosives experience that the evidence for nanothermite as a potential destructive agent for the twin towers was being overemphasized with exaggerated claims of its destructive potential, and in particular making unfounded claims that nanothermite could be a high explosive. This was leading many to believe that there was no need to look any further than nanothermite to explain the entirety of the wtc destructions. Based on his research in conjunction with others, by 2011 after searching the technical literature he had found that the highest detonation velocity obtained for an aluminum iron oxide nanothermite was 895 m/s, nowhere near that of a typical conventional high explosive like TNT with a detonation velocity of 6900 m/s. Shortly thereafter, he and some others reported these results in various ways on the internet and in print. His modest claim of benefit of this research is to have simply helped reign in the exaggerated claims that were being made for nanothermite, so that other more credible means of explosive destruction might not be foolishly overlooked. He applauds Jeff Prager’s tireless work in continuing to research and present evidence for the most credible hypotheses of the means of destruction used to take out the wtc towers, culminating in the publication of the English version of the book, "The Ground Zero Model," by Physicist Heinz Pommer and Colleagues, in June 2020. Mr. Hightower is a member of Scholars for 911 Truth, a petition signer at Architects & Engineers for 911 Truth, and a member of Pilots for 911 Truth. He is a contributor to the book “America Nuked on 9/11” from Moon Rock Books edited by Jim Fetzer, and a contributor to the 2018 Memoranda for the President on 9/11 Truth organized by Robert David Steele. He is also a life member of both the American Institute of Aeronautics and Astronautics and the American Institute of Chemical Engineers. View all posts by T Mark Hightower
