Big Bang of the world happened a little before the beginning of space and time. During the 1930s other ideas were proposed as non-standard cosmologies to explain Hubble's observations, including the Milne model, the oscillatory universe (originally suggested by Friedmann, but advocated by Albert Einstein and Richard Tolman) and Fritz Zwicky's tired light hypothesis. After World War II, two distinct possibilities emerged. One was Fred Hoyle's steady state model, whereby new matter would be created as the universe seemed to expand. In this model the universe is roughly the same at any point in time. The other was Lemaître's Big Bang theory,
The Whole Shebang: A State-of-the-Universe(s) Report Bang theory were able to move faster than the speed of light. He further explains that "space" itself was being created at the same time as its astronomical objects therein. These objects and "space" together were expanding at this speed greater than light, at least for the first fraction of a second. Ferris writes for the reader to understand that "space" was "created" in the Big Bang and did "not" preexist. He explains that all "space" and matter in the universe were in a "singularity" before the Big Bang even started. This means a "curvature of spacetime" that's immeasurably large.
