Alas, nowhere is there 'midday the sun is high in the sky' or anything like that - it makes a lot more sense this way and outright says that they kept it around to use for the betterment of life, seeding new planets, and self preservation, and that admittance of unauthorised persons would suffer 'penalty of the highest degree' - presumably it was guarded while the Ancients' society endured, though of course, that wouldn't explain why the 'halls of creation' would not be sealed properly.HEREIN CREATION SLEEPS

Alas, this can't really be taken as canon, but certainly gives an interesting perspective into what the props department, at least, thought the thing had been used for by the ancients, and the legal oversight in its use.
It also implies those stone monuments are actually made using hammers and chisels, too. Ooops.
