Jorrie, it's a fine piece of work! I have to say it was a real delight to see Part 3 when I got up this morning.

It's nice to see the two main horizons (the cosmic event horizon and the particle horizon) made easily calculable by the reader---and that they make sense as two parts of the same integral. One as the integral from zero to one, and the other as the same integral taken from one to infinity.

Potentially, I think, by giving a newcomer to cosmology a hands-on grasp of how basic features of the universe can be calculated (by anybody!) you make the subject less ad hoc, and above all less frustrating and confusing.

BTW do you plan to ask Greg or someone else on the staff to consolidate the three parts?
And are you at all tempted to continue and add a part 4 : ^)
Not sure what that would entail---these three pieces seem to form a fairly complete whole---but you might have ideas for a part 4 (although at the moment I can't think what it might be.)

Maybe there's something I could write myself that could continue, complement, expand somehow on this base. If you have any ideas for that let me know (if you prefer via PM.)

There is a drop down at the top of each article linking the parts together

That would be awesome!

As I said near the end of part 3, I am thinking that the 3 types of recession rates that we have in the LightCone calculator might be a logical follow-on. Plus perhaps a post-script of some sorts, as you have suggested before (and which you indicated that you are willing to write).
