New release of Jorrie's tabular calculator.
http://www.einsteins-theory-of-relativity-4engineers.com/LightCone1.0/LightCone.html
this is clearly the best on-line cosmology calculator for the general user on the web.
Hands down.
Lightcone rules. that's all there is to say. Check it out.
to get column definitions and explanations of the various quantities being tabulated (scale factor, Hubble radius R, proper distance now D, and then Dthen
just click the button that says "show column setup"
when you know the information therein, click the same button which now says "hide column setup"
Congratulatons Jorrie. Great job!
==================
PS the Dthen column sketches the proper distance outline of the past lightcone. Gives its radius at each stage of past history. So the tabulator's name is appropriate. That column is of central importance. All the galaxies we are now seeing live on that lightcone (which because of expansion has its own distinctive non-conical shape.)
