We welcomed back to the show Louise Riofrio to discuss her new book, “The Speed of Light.”  Remember that if you order this book through Amazon to use the OGLF Amazon portal so Amazon will make a contribution to TSS.  Instructions are on both The Space Show and our blog’s websites.  For more information, visit Riofrio’ s blog at http://riofriospacetime.blogsot.com. During the first segment of our 91 minute program, Louise told us about new developments and her work since her first Space Show appearance on Oct. 27, 2008.  She told her about her science work and related travels at JSC and her work with the moon rocks.  She also explained how her work with the moon rocks was important to human spaceflight, especially a return lunar mission and an asteroid mission.  She talked about why a lunar return mission was so important for science & why it was better to have astronauts on the mission rather than only robotic.  Out of this discussion came another SLS discussion as Louise pointed out the need for heavy lift for a lunar or any BLEO mission.  I explored her thoughts and opinions on SLS, asking her about the perspectives provided by those not supporting SLS.  In my opinion, Louise put forth excellent arguments in support of SLS during the show.  I even suggested she become the spokesperson for SLS and lunar return missions given how well she articulated and explained the need for SLS.  Louise also spoke about the distance from Earth to the Moon and the lunar orbit, referencing the LLRE (The Lunar Laser Ranging Experiment) from the Apollo era.  She used information from this device in comparison with three other measuring methods to support her theory that the speed of light is slowing down.  Listen to her explanation behind her theory assumptions.  Louise then mentioned the very accurate atomic clock soon to go up to the ISS, ACES (see http://www.esa.int/Our_Activities/Human_Spaceflight/Human_Spaceflight_Research/Atomic_Clock_Ensemble_in_Space_ACES).  She said this would be very helpful in detecting and clarifying the change in the speed of light.  John from Ft. Worth called with several questions and comments about the speed of light.   Next, Paul asked a series of email questions about time travel.

In the second segment, we started off discussing time travel and speed of light changes for a multi-generational human mission.  Louise introduced us to time dilation.  John in Montana asked about GPS timing & the change in the speed of light.   Christine emailed a question about an RTM mission and asked what might change if the speed of light is slowing down.  Next, we talked about Planck units and the equation GM=TC^3 which is the same as M=R=t.  Peer review was discussed as were the challenges of getting new theories introduced into the literature.  As you will hear, old ideas do not go lightly into the dark, so to speak.  Louise then talked about having discovered a lunar orbit anomaly and referenced her paper, “Calculating a Lunar Orbit Anomaly” which you can download at http://www.lpi.usra.edu/meetings/lpsc2013/pdf/2436.pdf.  As the program neared its end, I asked our guest about her idea that there might be a mini black hole in our sun.  Louise told us about her theory & talked in general about mini black holes.  Our last subject dealt with her interest in positive pressure suits for IVA purposes.

If you have comments/questions, please post them on TSS blog. You can reach Louise through her blog or me.

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, https://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.
