With regards to OrthodoxJew's thread about
Nahmanides and the Big Bang and people not having access to the source material, Sefaria.org, a huge online library of Jewish texts, is working on a public domain English translation of Nahmanides commentaries - his commentaries on Genesis are available
here. It is still mostly incomplete, but if OrthodoxJew tells us where to look we could see if the relevant passage is there. The whole thing is there in Hebrew if anyone else understands that.
Reading the sections I have looked through gives you a good idea at least of Nahmanides' worldview, and allows you to judge pretty clearly whether his cosmology accords with modern science (I'll give you only one guess).
