Endless inflation seems to be everywhere at the moment, including on this episode examining the nature of infinity. Brian and Robin dive through the back catalogue to discover there might be no limit to the number of parallel universes that exist. This leads to an argument between astronomer royal Lord Rees and comedy producer John Lloyd, who says the whole suggestion is total speculation. Even cosmologist Carlos Frenk can\u2019t get his head round the idea, as he contemplates the suggestion that new big bangs may be happening all the time.
