▼ The Big Bang theory represents cosmologists' best attempts to reconstruct the 14 billion year story of the universe based on the sliver of existence visible today.
Different people use the term "Big Bang" in different ways. Most generally, it illustrates the arc of the observable universe as it thinned out and cooled down from an initially dense, hot state. This description boils down to the idea that the cosmos is expanding, a broad principle analogous to survival of the fittest in biology that few would consider debatable.
More specifically, the Big Bang can also refer to the birth of the observable universe itself — the moment something changed, kickstarting the events that led to today. Cosmologists have argued for decades about the details of that fraction of a second, and the discussion continues today.
The classic Big Bang theory
For most of human history, observers of the sky assumed it eternal and unchanging. Edwin Hubble dealt this story an experimental blow in the 1920s when his observations showed both that galaxies outside the Milky Way existed, and that their light appeared stretched — a sign that they were rushing  away from Earth.
George Lemaître, a contemporary Belgian physicist, interpreted data from Hubble and others as evidence of an expanding universe, a possibility permitted by Einstein's recently published field equations of general relativity. Thinking backwards, Lemaître inferred that today's separating galaxies must have started out together in what he called the "primeval atom."
The first public use of the modern term for Lemaître's idea actually came from a critic — English astronomer Fred Hoyle. On March 28, 1949, Hoyle coined the phrase during a defense of his preferred theory of an eternal universe that created matter to cancel out the dilution of expansion. (▪ ▪ ▪)

Latest reports seem to indicate black holes are not holes but conduits to alternate multiverses. If so a universe could be a bubble that gets formed in the fabric of time and where the streaming in of material happens in a universe as a black hole gobbles from another. It may be like a convection current where the universe is working to equalize matter and energy across all it's instances in all multiverses.
