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.
