We welcomed Kelvin F. Long to the show to discuss both his new book, “Beyond the Boundary” and interstellar human spaceflight.  During the first segment of our 1 hour 51 minute show, Mr. Long introduced his book which has been published on http://www.lulu.com by The Initiative for Interstellar Studies.  We discussed the book and many of the contributing authors, then I asked our guest if we might have interstellar starships next century.  Mr. Long said it was possible but also a very big problem so you do not want to miss this comprehensive discussion.  During this segment, we addressed warp drive, worm holes, negative energy, and public sector responsibility for interstellar spaceflight.  Kelvin provided us with some interesting history going back to the 1930s and the British Interplanetary Society (BIS) early work about rockets to the Moon.  Later, nuclear propulsion came up in terms of both fission and fusion technology.  As part of this discussion, Kelvin mentioned problems caused by the Outer Space Treaty. In addition, we discussed Project Dragonfly which is a laser sail competition, robotic payloads, Project Daedelus, and more.  Listener Helen asked our guest about the plausibility of a hibernation ship and BJohn asked about gravitational forces of the Sun and interstellar travel.  John called from Ft. Worth to seek a clarification about the Outer Space Treaty comments and to talk about NTG usage in space.

In the second segment, Kelvin talked about Project Icarus and directed us to http://www.icarusinterstellar.org.  We also talked about the growing interstellar community and some of those in different industry segments working for and supporting interstellar travel.  Tim called to ask about the fission fragment rocket and Mach’s thruster.  BJohn asked about ET civilizations and the Fermi Paradox.  Kelvin had much to say on this subject.  Near the program’s end, I asked Kelvin for an action plan. He proposed one covering three areas:  Education, Business, and New Technologies.  Make sure you here the details of his plan.  Our guest offered us powerful closing comments.

We welcomed back Marc Millis to discuss the needed advanced physics for interstellar spaceflight plus his take on the new hit movie, “Interstellar.”  During our 90 minute program without a break, Marc debriefed us on his take on the science behind and involved with the new movie, “Interstellar.”  He said there were things about the science and the movie that he liked and that they did a good job with and other things that got a less than positive grade.  For example, he said the way the movie depicted the worm hole was nicely done & he explained why.  One area he did not like was the shuttle like craft being blasted to space on a Saturn V like vehicle but then going back and forth to the other planets.  He said this raised serious fuel issues & questions.  He also said the time dilation effects were confusing and inconsistent.  We talked about black holes, then Marc mentioned the Incessant Obsolescence Postulate which suggests that should a probe or occupied spaceship be launched to the stars, eventually a more modern one will pass it in the future enabling it to reach the destination a lot sooner than the initial ship.  Marc returned to discussing worm holes and the negative energy needed for them to be useful tools for interstellar spaceflight.  A listener from Boston asked about nuclear propulsion and if that was the advanced propulsion needed for interstellar flight.  Marc talked about both fission and fusion propulsion & their respective applicability & usefulness for interstellar flight.  SLS John called for an advanced physics discussion which included the inertial frame of reference and gravity discussion, Mach’s principle, the Equivalence principle, the Higgs particle and more.  This is a great discussion, don’t miss it.  Another listener asked Marc what the minimum advanced physics and propulsion would be to get started with an interstellar flight, then evolving to more advanced tools over time.  Marc outlined a plan he talked about earlier for doing small steps at a time as opposed to a giant leap needing far more advanced technology than what is available now or will be in the near future.  Another listener asked a similar question focusing on the minimum amount of knowledge needed to get started with interstellar spaceflight.  Pooley called in to talk about the Equivalence Principle.  Marc talked about the Tau Zero Foundation and its needs, and then Beth asked why we don’t focus on Mars or the clouds on Venus, both of which are more doable than interstellar flight.  Marc said we need to focus on both at the same time so don’t miss his excellent answer.

Guests: Dr. Richard Obousy, Dr. Eric Davis, Dr. Harold Sonny White.  Topics:  Faster Than Light (FTL) Travel, Warp Drive, Interstellar Travel. Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.  We welcomed our three guests, Drs. Obousy, Davis, and White to the program to discuss FTL travel, warp drive, and interstellar flight.  More information is available at the Icarus Interstellar website, http://www.icarusinterstellar.org.  We did not take a break during our program.  Also, at times our discussion was technical and scientific. I looked up many terms & used my search engine frequently during the discussion given the advanced nature of the subject and our discussion.  Don’t be shy about looking up that which you may not understand or know about. I promise, if you do it will be well worth your time.  We started with an introduction to Icarus Interstellar, FTL travel, and why interstellar propulsion & travel is important.  Our guests then suggested the two most common approaches to FTL travel included warp drive and worm holes.  For most of the program, we focused on the characteristics and research around warp drive.  Our guests explained their research, including how they were able to develop the theories that reduced the amount of energy needed for warp drive from Jupiter size energy requirements to energy requirements representing the approximate mass of Voyager 1.  Our discussion addressed the Miguel Alcubierre warp drive in light of the advanced work by Dr. White and others.  The concept of the McMonigal Fatal Flaw was addressed with our guests explaining why it was not applicable.  The workings of the warp drive were explained and though the discussion was heavy in physics, I urge you to take the time and embrace & learn about the advanced theoretical physics subjects discussed by our guests.  Later, a listener asked about the use of a sun gravitational lens telescope at a specific AU from the sun as perhaps an alternative to interstellar flight.  As you will hear, such a device would likely be a good tool enhancing FTL travel, not replacing it.  As our discussion progressed, or guests rebutted many of the warp drive criticisms. Near the end of the program, we talked about what was needed to go from the lab and theory to small scale demo experiments to prove out the concepts.  Our guests referenced to the Chicago Pile-1(CP-1) 1942 nuclear experiment & the subsequent step by step evolution of nuclear technology.  Our guests talked about starting small with a demo proof and evolving upwards with more and more discovery, technology, and engineering.  Another example cited for the typical development path included the discovery of the electron in 1897 followed by the discovery of the proton in 1917, and the discovery of the neutron in 1932. Throughout our discussion, our guests put forth compelling reasons why we should be developing FTL travel and interstellar spaceflight.  Their respective concluding comments reinforced the importance and why of our being interested in FTL and exotic concepts.
