We welcomed back Dr. Jim Woodward to the program to discuss the Mach Effect, Mach thrusters and drive, and breakthrough propulsion. During our discussion, Dr. Woodward mentioned his book, “Making Starships and Stargates which you can order at http://ssi.org/exotic-propulsion-initiative as this allows SSI to get a royalty payment on the sale of the book. If you buy the book through Amazon using TSS/OGLF portal, The Space Show gets a percentage of the sales price of the book. In addition, the Charles Platt article, “Strange thrust: the unproven science that could propel our children into space” can be found here: http://boingboing.net/2014/11/24/the-quest-for-a-reactionless-s.html. Finally, Dr. Woodward mentioned the paper written by Dr. Heidi Fearn, “New Theoretical Results for the Mach Effect Thruster.” You can download this paper at www.researchgate.net/publication/280134421_New_Theoretical_Results_for_the_Mach_Effect_Thruster. Note that in the final minutes of our program, Dr. Woodward spoke very softly and we were unable to get some of what he said as part of his final comments. While the 1 hour 56 minute program was divided into two segments, this summary will be in one segment only and short as the papers above tell the story. I urge you to read them and become familiar with Dr. Woodward’s work either before or after listening to this discussion which was at times very technical and heavy in the theoretical physics fields for gravitational forces, electromagnetic forces and more as he described the Mach Effect. In addition to the physics, since Dr. Woodward’s work is dependent on funding so he spent a good amount of time in both segments answering questions and telling us what it was like trying to get funding, approved proposals, etc. for cutting edge work or even work considered to be out of the box or on the fringe. His realistic assessment of the challenges posed by his and similar work goes to the point of why we don’t see more out of the box science & advanced projects being financed. In addition to the physics and funding discussions, we talked timelines for his having commercial uses for small Mach thrusters which would start off servicing satellites. This discussion covered both segments.

Please post your comments/questions on TSS blog above. You can contact Dr. Woodward through me at drspace@thespaceshow.com or his Cal State Fullerton website.

We welcomed Dr. Paul Davies to this 65 minute discussion about his contribution to the excellent book, “Starship Century: Toward the Grandest Horizon.” Other topics included interstellar travel, microbiology, human spaceflight, Mars, ET and much more.  We started our discussion with his Afterword in the “Starship Century” book and I asked him about his comments regarding microbes.  One quickly learns from reading his Afterword that it is not the propulsion and engineering that presents the greatest challenge to interstellar travel but what happens to essential microbes needed for life in microgravity and the space environment.  We learned that even in LEO such microbes can transform and become toxic to life.  This is a fascinating microbiology discussion regarding deep space missions to Mars, the Moon, and long interstellar travel. Don’t miss what Dr. Davies said about microbes as it opens up an entirely new study in human factors for human spaceflight.  Other issues we talked about included planetary contamination, microbial ecosystems, figuring out the minimal needed for sustainability regarding the good microbial environment.  Also, what microbes are crucial and those that might be irrelevant for the spaceflight passengers as well as for animals and plants needed for sustaining the mission.  Dr. Davies was asked that given microbiology being a bigger challenge than propulsion and engineering, were we close to having propulsion and engineering for interstellar travel.  You will appreciate his very “witty” answer to this listener’s question.  Faster than light travel came up and so did the work being done around the Alcubierre Drive.  Dr. Davies had much to say about faster than light travel, the speed of light, physics, and related disciplines.  In this discussion, we also talked about both black holes and worm holes.  Later, we talked about the possibility of life in the solar system other than on Earth.  You might be surprised by some of what Dr. Davies said, including the probabilities that Earth might have been visited over 100 million years ago.  Don’t jump to conclusions, listen to the discussion first.  Helen of Atlanta asked why bother with interstellar travel when we can’t even return to the Moon. Again, another terrific response by our guest.  More came up on the Fermi Paradox, the need to stay grounded in fundamental science but to have a vision and healthy skepticism.  Viking and Gil Levin came up regarding the possibility of life on Mars and the reluctance of NASA to do biological experiments regarding the possibility of life on Mars.  A listener asked our guest about ET conspiracy theories and government cover-ups.  In closing, Dr. Davies reminded us to have and conduct healthy speculation which means always staying in tune with fundamental science.  That is what separates speculation from fantasy, Kool Aid, and La La thinking.  As the program was ending, we talked some about his work in cancer research.
