Greetings My name is Charles Sven:
The basic problem with cosmology is that physics cannot account for our existence; the creation of our universe.
What obscures that event is the reworking of Einstein's equations by Wilhem de Sitter, Alexander Friedman, and Georges Lemaître.
What should raise a powerful red flag that their work obscures understanding is -- Friedman's 1923 notation - he writes "This brings to mind what Hindu mythology has to say about cycles of existence, and it also becomes possible to speak about the " creation of the world from nothing,"
As if that wasn't enough we have Georges Lemaître's published comments in a 1931 letter to Nature magazine where he says IF! "If the world has begun with a single quantum," - HIS IF! becomes that singleton forming in de Sitters 1917 expanding space and according to - Friedman's Hindu myth -- out of nothing
--- So much for reworked Einstein's general relativity.
All I did was examine all we know about the closest thing to a singleton that we find on Earth --- the atom.
And following Richard Feynman's method of attach; start from scratch - just use his most important tool -described by Einstein -in Einstein's 1921 address to science " the truth of physics and other natural sciences can only be established through observations or experiments."
The result is this essay describing the physics of Dark Energy, - how we physically observe its existence, and describe the mechanical conversion of dark energy into atoms - This puts us at the time of the big bang physically observing the creation of our Universe with 3D physics. Mystery of creation solved!
