We welcomed back Eric Lerner for updates on his Focus Fusion work and then later, his work in cosmology as he challenges the Big Bang & expanding universe theories.  In the first segment of this 1 hour 40 minute show, we focused on fusion.  For more information, visit http://focusfusion.org.  Since much of this discussion involves physics, technical explanations, and more, referring to the website will be helpful.  Eric started out with an overview of focus fusion (Aneutronic Fusion).  He made clear their goal was to demonstrate the scientific feasibility of focus fusion.  Eric then described the challenges, possible solutions and progress being made in reaching their goal.  I suggest you review these website pages to help you understand what he talked about:  http://focusfusion.org/index.php/site/category/C36; http://focusfusion.org/index.php/site/category/C63; http://focusfusion.org/index.php/site/category/C70.  During this segment, Eric explained in detail the process, the physics, the science and more of what they do, have done, and still need to do.  We talked about pulse power, time sequences, the amount of power needed, and what has to happen to get more energy out than what they put into their reactor.  Marshall called to ask about computer power needed and simulations compared to actual experiments.  Eric also talked fuel options and then he talked about their financial needs.  He said they would soon be doing both a short movie and a Kickstarter program.  In fact, he made a call for volunteers so if you are interested, email him at eric@lphysics.com.  Questions came up about the safety of their work, then listeners asked how they contain such high temperatures, even if for a fraction of a second.  He talked about the need for using tungsten & we talked some about tungsten supplies and pricing.  Charles called in with several questions and comments about fuels and then about instead of using tungsten electrodes why not use boron or beryllium as the low atomic weight would contaminate the plasma less.  Charles & Eric has a very interesting discussion about these matters.  We then did a theoretical comparison of the potential cost of fusion energy with coal, natural gas & other conventional fuels.  Near the end of the segment, Eric was pressed for timelines to commercial breakeven if he had adequate funding.  Direct Energy Conversion was our last session topic.

In the second segment, Tim called to ask about fusion for space propulsion.  Next, Eric talked about cosmology as he said there was a debate about the Concordance Model which supports an expansive universe and The Big Bang Theory.  Eric challenges this and in this segment, provided support for his challenge to the Concordance Model of the Universe.  He also pointed out that his book on the topic is still in print so if you are interested, use the OGLF Amazon portal to buy “The Big Bang Never Happened.” OGLF portal instructions are in all program summary statements and blog archives.  You can also email me for help at drspace@thespaceshow.com.  Eric’s discussion of The Big Bang Theory and why he says it is likely incorrect was most interesting and I urge you to carefully listen to what he had to say about this & cosmology in general.  He also talked about how difficult it is to be published if you have a contrary theory and how peer review science flows to the status quo.

Dr. Richard Obousy, Dr. Eric Davis, Dr. Harold Sonny White, Friday, 1-4-13

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, http://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

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.

The John Batchelor Show “Hotel Mars,” Wednesday, 6-20-12

http://archived.thespaceshow.com/shows/1801-BWB-2012-06-20.mp3

Guests:  John Batchelor, Dr. Seth Shostak, Dr. David Livingston.  Topics:  SETIcon II Conference, science fiction & space science.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Written transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. This program is archived on The Space Show website, podcasting, and blog sites with permission from John Batchelor. Please visit the John Batchelor Show website for more information about this fine program, www.johnbatchelorshow.com. During our 11.5 minute discussion, Dr. Shostak talked to us about the upcoming SETIcon II Conference sponsored by the SETI Organization.  For details about the conference, visit www.seticon.org.  The three of us talked about the programming, many of the guests and panels, but John also asked about the Kepler Space Telescope and finding exoplanets, the habitat zone, and life elsewhere off Earth.  Dark matter, dark energy came up, along with the question which is addressed by this conference concerning if Earth is a miracle or if Earth is more common with life in other places even if not yet discovered by us here on Earth.  In looking over the program agenda, you will recognize many of the speakers and panel members as Space Show guests and actual scientists and academics.  You will hear me talk about why this is a special type of sci-fi conference.  For those of you in the Bay Area or able to attend it this coming weekend, I strongly recommend you do so. It is affordable, it will be fun and above all, SETIConII will be information packed and educational.

If you have comments or questions about this program, please post them on The Space Show blog. If you want to email either John or Seth, send your note to me and I will forward it for you.

Dr. Chris Impey, Sunday, 4-15-12

http://archived.thespaceshow.com/shows/1752-BWB-2012-04-15.mp3

Guest:  Dr. Chris Impey.  Topics:  We discuss Dr. Impey’s new book, “How It Began: A time-Traveler’s Guide To The Universe” along with astronomy, physics, and cosmology topics. We also discussed space policy and the future of human spaceflight plus science missions. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.  We welcomed Dr. Chris Impey back to the program to discuss his new book.  Remember, if you buy the book from Amazon using the following URL, Amazon makes a contribution to The Space Show/OGLF:  www.amazon.com/How-It-Began-Time-Travelers-Universe/dp/0393080021/ref=onegiantlea20.  For the Kindle version, use www.amazon.com/How-It-Began-Time-Travelers-ebook/dp/B005LW5J30/ref=onegiantlea20.  During the first half of the program, Dr. Impey talked about the book’s structure which is a bit different from other books addressing similar topics.  For example, the further outward in the universe you go via reading the book, the more backward in time you go which is why the book is a time-traveler’s guidebook to the universe.  Dr. Impey explains this to us and the going back in time is with us for the entire Space Show discussion.  Our first stop was our Moon and our guest had much to say about it, including its origins, why and how it orbits Earth at about 240,000 miles, and more.  We also learned what Earth would probably be like without the Moon.  As we went into deeper space after leaving the Moon, we talked about the Kepler Space Telescope (KST) and finding exoplanets plus searching for exomoons.  A listener asked about the delay encountered with supernova 1987A and our guest explained this to us.  I also asked our guest about his statement on page 19 at the bottom about time and Apollo becoming a “distant cultural memory.”  This turned into a lively discussion you don’t want to miss.  We then talked about human spaceflight (HSF) with Dr. Impey suggesting that due to the high cost of HSF and the constant improvements with robotics, we might very well see advanced robotic missions over the coming years rather than human missions which may prove unaffordable.  Don’t miss this conversation, it may very well be an accurate forecast for the future for HSF and robotic missions.

In the second half of our program, we moved out into the universe and talked about the Big Bang, First Light, and the James Webb Space Telescope (JWST).  We also talked about large Earth-based telescopes, Hubble, and looking back close to 13 billion years with JWST while the universe is about 13.7 billions years old.  We talked about why one cannot see the origins of the Big Bang with optical telescopes, but what we can “see” with microwaves.  A listener asked about the Cosmological Principle and another asked about human time travel.  This brought up the topic of black holes.  Questions came up about string theory and the Multiverse, and then John called in to discuss both dark energy and dark matter which turned out to be another fascinating discussion led by Dr. Impey.  Later, we went back to discussing HSF and we learned about the potential for nanobot probes for interstellar missions.  Fleets of such probes acting in a sort of relay fashion might just be real someday.  Near the end of the program, Dr. Impey discussed geopolitics as a driver for space exploration and said more about the early time after the Big Bang for the first 100 million years or so.
