My guess is that the temple will be rebuilt sometime about when warp drive is developed. Star Trek cannon has it that the Warp Drive was developed in 2063. So sometime about then. 2063 also roughly coincides with with the date that Issac Newton put for the end of the world. https://www.openculture.com/2015/10/in-1704-isaac-newton-predicts-the-world-will-end-in-2060.html
Old Isaac was a mathematician and a numerologist so he must have been right...................😁
