There are as many, if not more, scientific theories as to the origin of our universe, as there are differing religious bodies, such as Christianity, Hindu, Abrahamic, Muslim, etc.
One of which, is a theory put forward by Niayesh Afshordi, an astrophysicist with Perimeter Institute for Theoretical Physics in Canada, which he believes, could explain the singularity within a Super massive Black Hole, from which singularity our ‘Three Dimensional’ Universe was born.
Niayesh Afshordi, proposes that our three-dimensional universe floats as a membrane in a “bulk universe” that has four dimensions and that the “Bulk Universe” has four dimensional stars, which go through the same life cycles as our three-dimensional stars.
The most massive ones explode as supernovae, and their central core collapses into a black hole, (As a Singularity) like in our universe, only in four-dimension. The four-dimensional black hole has its own four dimensional “Event Horizon,” the boundary between the inside and the outside of a black hole.
In a three-dimensional universe, the event horizon appears to be two dimensional. In a four-dimensional universe, it appears to be three dimensional. The four-dimensional black hole, then blows apart, (THE BIG BANG) with the leftover material forming a three-dimensional membrane surrounding a ‘Three Dimensional’ event horizon, which expands---and is essentially our universe.
So, according to the theory proposed by Niayesh Afshordi, our universe is the vomited-up guts of a Super massive fourth dimensional black hole, in which the singularity that is said to have been the origin of our three dimensional universe, had been crushed. The expansion of the event horizon explains our universe's expansion; the fact that its creation stems from another 4D universe explains the weird temperature uniformity.
As attractive as Niayesh Afshordi’s theory is, I will continue to believe in the eternal oscillating universe, which is the evolution of the eternal energy that has neither beginning or end, and that each stage of its activity is a separate generation, and each generation of its eternal evolution, occupies its own position in Space-Time.
As the scriptures state that God gathers all creation back to himself, before creating for us a new heavens and a new earth, (A new universe) I will continue to believe, that this entire universe, which began as a ‘singularity,’ will burn up and fall as fire into the Great Abyss, which is created by the black holes within the condensing Galaxies devouring each other, where it will be crushed back into the singularity from which it was created, only to be blasted out and resurrected to continue on in its eternal process of evolution.
As said previously, “According to the ancients, we live in an eternal oscillating universe that expands outward and contracts back to its beginning in space time. A universe that exists in the two states of seemingly visible matter and invisible energy.”
“Universe after universe is like an interminable succession of wheels forever coming into view, forever rolling onwards, disappearing and reappearing; forever passing from being too non-being, and again from non-being to being. In short, the constant revolving of the wheel of life in one eternal cycle, according to fixed and immutable laws, is perhaps after all, the sum and substance of the philosophy of Buddhism. And this eternal wheel has so to speak, six spokes representing six forms of existence.” ---- Mon. Williams, Buddhism, pp. 229, 122.
The days and nights of Brahma are called Manvantara, or the cycle of manifestation, ‘The Great Day,’ which is a period of universal activity, that is preceded, and also followed by ‘Pralaya,’ a dark period, which to our finite minds would seem as an eternity, or but a moment in time.
‘Manvantara,’ is a creative day, a period of universal activity of light and life, as seen in the six days of creation in Genesis. ‘Pralaya,’ is the evening that proceeds the next creative day, and is seen as the period of rest for the “GREAT THOUGHT’. The six periods of Creation and the seventh day of rest in which we now exist are referred to in the book of Genesis 2: 4; as the “GENERATIONS OF THE UNIVERSE.”
The English word “Generation,” is translated from the Hebrew “toledoth,” which is used in the Old Testament in every instance as ‘births,’ or ‘descendants,’ such as “These are the generations of Adam,” or “these are the generations of Abraham, and Genesis 2: 4; it is written concerning the six days of creation; “These are the generations of the Universe or the heavens and earth, etc.” And the ‘Great Day’ in which the seven generations of the universe are eternally repeated, is the eternal cosmic period, or the eighth eternal day in which those who attain to perfection, are allowed to enter, where they shall be surrounded by great light and they shall experience eternal peace, while those who do not attain to perfection are cast back into the refining fires of the seven physical cycles of endless rebirths that perpetually revolve within the eighth eternal cosmic cycle.
To the Hindu, Lord Krishnu, the ‘EIGHTH’ manifestation, or rather, the eighth descendant =generation of Vishnu the savior, is the Supreme Personality to have developed within the eighth manifestation of Brahman, who, to the Hindu, is the essential reality of the universe, the eternal and divine spirit, from who all being originates and to who all must return at the close of each period of universal activity.
Enoch the righteous, wrote that God created an ‘EIGHTH
’ day also, so that it should be the first after his works, and it is a day eternal with neither hours, days, weeks, months or years, for all time is stuck together in one aeon, etc, etc, and all who enter into the generation of the Light beings, are able to visit all those worlds that still exist in Space-Time, but not in our time.
A series of worlds following one upon the other-- each world rising a step higher than the previous world, so that every later world brings to ripeness the seeds that were imbedded in the former, and itself then prepares the seed for the universe that will follow it.
in other words; 'A never ending, everlasting, universal 'MIND=THOUGHT', evolving from generation to generation.
