In the movie, The Oxford Murders, the young graduate student, “Martin” (Elijah Wood), wanders into a closed system and inadvertently disrupts it. Martin is a “knight errant”, a “butterfly effect”, by whom, contrary to his intent, the closed system is altered and four murders occur. Don Quixote is also a “butterfly effect”, a “knight errant” who alters lives beyond his original intent.
Sometime in the 1930s or early 1940s, a conference was held to discuss and ponder the origin of the universe. A book first published in 1942, Generation of Vipers, incidentally mentions how various ideas were under consideration. “One notes,” wrote the author of Generation of Vipers, Philip Wylie, in a footnote to a subsequent edition of his book, “with something of a sigh, how the ‘universe’ now ‘changes’ almost annually.”
So, for example, a Dr. Robert A. Millikan, then president of the California Institute of Technology, sought a “creating God” to tie into origin of the universe theory. “For a while, after that, the expanding universe people had the thing in hand and we were rushing apart on galaxies that ran as trains to noplace…” Then someone named Fred Hoyle, along with “some bright Britishers,” came up with a “constant-if-inexplicable-creation-of-hydrogen universe.” 
Wylie, in his footnote, sighs and comments that he is “still amused” at how “so many people are compulsively ridden with a need to ‘find’ an ‘eternal’ universe” and that the various origin of universe theories illustrate in a nutshell how “mankind invents every, little separate ‘god’ according to his knowledge of himself (and his ignorance) at the moment.” 
The Fred Hoyle who favored the “constant-if-inexplicable-creation-of-hydrogen universe” theory was an English astronomer who rejected the expanding universe “big bang” theory.  In fact, it was Hoyle himself who sneeringly originated the term “big bang” to describe the Lemaître/Gamow explosively expanding universe theory. 
The mathematicians, as usual, play a role in these various theories. How the mathematicians intersect with physics and astro-physics is explained well by the late Morris Kline in his book, Mathematics for the Nonmathematician (originally titled Mathematics for Liberal Arts Majors, as I recall). Off-and-on, for years, I had wondered just how Isaac Newton had arrived at his second law of motion, F=MA. I even went so far as getting a copy of Newton’s Principia in hopes of discovering how exactly do we know that Force equals Mass times Acceleration (F=MA). The Introduction to my copy of Principia was good because it delved into Newton’s fascination with Alchemy, but the book itself was hopeless even for the mighty Ersjdamoo. However later I came across Kline who finally explained how Newton arrived at F=MA, and he does it in just one chapter!
The latest mathematician to weigh in on origin of universe theory is Professor Saurya Das at the University of Lethbridge, Canada. He did the numbers and concluded the universe did not have a beginning! “It lasted forever,” stated Saurya Das. “It will also not have an end… In other words, there is no singularity.” 
In the 1978 movie, Animal House, college freshmen Lawrence “Larry” Kroger (Tom Hulce) is smoking marijuana with Professor Dave Jennings (Donald Sutherland). Larry has an epiphany: His fingernail is a universe, and he himself lives in the fingernail universe of a giant! That idea is not so ridiculous: St. Paul tells us, for example, “For in him we live, and move, and have our being; as certain also of your own poets have said, ‘For we are also his offspring.'” (Acts 17: 28) Paracelsus proposed that within each of us was an inner heaven with stars. Alchemist Robert Fludd explicitly based his work Utriusque Cosmi Historia (The history of the two worlds) upon the macro/micro correspondence. Gottfried Leibniz, co-inventor along with Isaac Newton of “the calculus” (they always insist you must call it “the calculus”), developed a metaphysics that explained the universe as the composite of an infinite number of non-spatial units called “monads” where each monad is like a microcosm and it “reflects” the entire universe. 
The current thinking of Ersjdamoo upon the “origin of universe” theories is substantially in agreement with the mathematics of Professor Saurya Das, that the universe always was and always will be. Ersjdamoo agrees with the Hindus, who proposed a universe which breathes. The Sanskrit terms for this are Manvantara and Pralaya, the great in-breathings and out-breathings. When the universe breathes in, it expands; when the universe breathes out, it contracts.
