Oscillating and multiverse constructs seem rooted in mumbo-jumbo math otherwise someone would outshine Einstein.

Not sure that "mumbo-jumbo math" has a meaning that I can glean. Math is math. Non-Euclidean geometry is still math. I'm not sure that, say, the math behind figuring out the speed of a falling object explains anything about objects or gravity, but it works and can be used for something. I'll take string theory and multiverse cosmologies over the bearded guy in the sky explanation. If nothing they are more aesthetically pleasing.

Ceci n'est pas un seing.
