DioneTheDiabolist, So its e) he found praying helpful = goady misleading statement.
I have had ideas whilst on the toilet, driving, lying in bed and quite a few other places, it infers nothing as to where the idea came from or the quality of the idea.
So when you say LeMaitre wrote in his journal during a retreat you are meaning absolutely nothing and are just being goady.
But to get more specific LeMaitre didn't even come up with an original thought. Cosmic expansion was demonstrated by Edwin Hubble 2 years before LeMaitre first proposed the idea of the 'primeval' atom. And even then, LeMaitre based it on the static state imagined by Einstein. But even if praying somehow gave him some 'new' information it was already redundant as Alexander Friedmann had already solved the maths for it a decade earlier.
But after a little more digging I find all that is well predated by Edgar Allan Poe who wrote a 40,000 word essay ‘On The Cosmography of the Universe’, (based on work by Humboldt). In it he suggests that the universe came out of nothing and indeed, had an origin, he contended that the universe filled with matter after a single, high-energy particle exploded and that, since the energy of the explosion is pushing matter outward, the universe must be expanding.
He went on to say space and ‘duration’ [i.e. ‘time’] are one thing, that there might be stars that emit no light, that there is a repulsive force that in some degree counteracts the force of gravity, that there could be any number of universes with different laws simultaneous with ours, that our universe might collapse to its original state and another universe erupt from the particle it would have become, and that our present universe may be one in a series.’
Apart from suggesting a Big Crunch, Poe was the first to explain Olbers’ Paradox (the night sky is dark despite the vast number of stars in the universe). Poe claimed, as many do now, that the universe is not old enough to fill the sky with light. The universe may be infinite in size, he thought, but there hasn’t been enough time since the universe began for starlight, travelling at the speed of light, to reach us from the farthest reaches of space.
Unfortunate at the time his work was decried as hyperbolic nonsense.
So we have a god giving a scientist an idea someone else already had, some mathematics that other people had already solved and a concept that someone else had already demonstrated. Why are gods revelations always after the fact?
Sorry for the long post, I enjoy science, and was interested to discover that LeMaitre was in fact an accidental/deliberate? carpet bagger.
