Many thanks to you, Zeeya - and for your email, Jonathan.

I had a look at what I'd written, and I should have said a bit more about a sentence in the first paragraph - "Cosmic expansion is accelerating because of the increased production of space-time by binary digits, Mobius loops and figure-8 Klein bottles ..."

The binary digits of 1 and 0 in Mobius loops and Figure-8 Klein bottles (I like to consider these things parts in what I call...

Thanks to Rodney Bartlett for his feedback (over on another thread) on my recent Discover article about dark energy. (It was while interviewing Brian Schmidt that I made the recording that's used in this podcast.)

I'm cutting and pasting Rodney's comments here because they fit the topic of the podcast:
