Speculations on the Architecture of the Celestial Temple was an essay written by Ke Hovath that looked at the Bajoran wormhole and the Prophets from both a religious and secular viewpoint.

In it, Hovath put forward the viewpoint that the wormhole could open into an infinite number of parallel universes if an appropriate "key" was found. Speculations on the Architecture of the Celestial Temple attracted the attention of Iliana Ghemor who kidnapped Hovath and his wife Ke Iniri and destroyed Sidau. Ghemor claimed the paghvaram, an Orb fragment, was the key to opening those locked doors. (DS9 novel: Bajor: Fragments and Omens)
