Interupting the flow of the story to make special mention of the first contributor to the show: Nick. If it wasn't worth mentioning, I wouldn't have. But it is. Thank you.

For those of you not familiar with Nick's words, it would be advisable to peruse them now, to enable you to get the full benefit of this particular broadcast. Also, before I charge into this, I'm not sure about the etiquette of making blogs and including references to other people who I don't know particularly well, yet, so, I'm sorry in advance, Nick. Great.

Okay then.

...

Well, sorry to appear to completely disregard you, Ad, but what you said, Nick, is incredibly interesting. I don't think I'd ever considered the ideas at the end of your comment, but after reading it, and thinking about it, it made me think about how you can define music. Like Ad said, us guys on earth define music as stuff we can hear, but I reckon the lads and ladettes from planets without an atmosphere similar to our own (a concept that hadn't until then occurred to me either), must have their own equivalent music. Now, for us, music is the word we use to describe the way the air vibrates when music is being played. (I've just ad libbed that, by the way, so after a bit more thought, I might not quite agree with it.) So to say it simply: Music is vibrations. And now would be a good idea to drop this for the time being, and continue this particular part of the discussion in the story proper.

What you said about Infinity is ridiculously interesting, as well. Like I said in the anecdote, I tend to relate things of this nature to numbers, and sizes in metres, or light-years, etc. (not that I can imagine how far a light-year is), so I'll have to stop talking about 'an Infinite number' of things, and just stick with... well... I don't know what I'll stick with. I'll cross that bridge when I come to it.

Your way to visualize the Universe as an infinite ocean with no surface, is very evocative. Bit difficult to grasp the concept, but after more thought (like almost everything) it'll become clear. And I've got a way to visualize the 4th Dimension that I'll furnish you with in due course. 'Tis quite good, methinks.

This thing about branes: I remember watching a programme on the goggle-box about this and the idea of there being about thirteen dimensions. I couldn't remember that they were called branes, but I'll trust you whole-heartedly on that. I don't think I'd really grasped the concept of them properly, but I think I'm getting close to it now. And when I first read your statement, 'This wasn't the birth of our universe, but it was the beginning of time,' I thought that was a bit dangerous, but now I think I know what you mean, and it sounds plausible, etc. I was sort of of the opinion that time never started and will never finish, but I think the way to look at it, is that... oh boy, erm... I'm sort of talking myself out of this, now. I was going to say that the way to look at it, is that time for Us started with the Big Bang, and that Time for the rest of the Universe had already been in existence. I'll have to think about that a bit more, or you'll have to explain it even better for me, before I come to a more solid conclusion.

Alright chaps, I'm winding down, here - don't give up just yet. Last point. And it's a quick one.

About New Scientist: I always seem to be a bit dubious about mags. Don't really know why - it's probably something built in to me. But somehow I'm (almost) always pleasantly surprised by them when I pick 'em up. I'll do a bit of burrowing around to see if I can find a copy of this New Scientist. And do a bit of praying that it's not too expensive when I find it.

...

Now, after that friendly interlude, let's return to the story, as planned.
