This evening, Friday, November 21st at 7:00 pm, David Goldberg & Jeff Blomquist, are doing a talk:
How to Build a Time Machine
This is at the Philadelphia Science Fiction Convention, in Cherry Hill, PA. Directions and so forth at www.philcon.org.
Time travel is one of the essential ingredients in compelling science fiction. Given that we’ve never built a time machine, how do we separate the “science” from the “fiction?” The authors of “A User’s Guide to the Universe: Surviving the Perils of Black Holes, Time Paradoxes, and Quantum Uncertainty” will give you the physics perspective on this. They’ll describe how to build a practical time machine and what you can do with it once you’re done. Following a short talk, the session will be open to general questions and discussion on the science of time travel.
I haven’t met Goldberg & Blomquist; I’m very much looking forward to seeing them in action this evening!
(Full disclosure time: I did a slide talk with essentially the same title, “How to build a (real) time machine” at this year’s Balticon & last year’s Philcon. My problem was how to strip the enormous amount of available material down to an hour’s worth! I will be very interested to see what Goldberg & Blomquist focus on! I will take copious notes & post a followup next week.)
