How did the Big Bang start from nothing?
The universal origin story known as the Big Bang postulates that, 13.7 billion years ago, our universe emerged from a singularity — a point of infinite density and gravity — and that before this event, space and time did not exist (which means the Big Bang took place at no place and no time).
What was our universe like before the Big Bang?
It’s possible that before the Big Bang, the universe was an infinite stretch of an ultrahot, dense material , persisting in a steady state until, for some reason, the Big Bang occured. This extra-dense universe may have been governed by quantum mechanics, the physics of the extremely small scale, Carroll said.
What best describes the universe before the Big Bang?
Stephen Hawking Describes the Universe Before the Big Bang. “In this [approach], ordinary real time is replaced by imaginary time, which behaves like a fourth direction of space… The history of the universe in imaginary time is a four-dimensional curved surface, like the surface of the Earth, but with two more dimensions.”.
What was God doing before the Big Bang?
A common statement about what God was doing before the Big Bang goes like this: He was preparing Hell for people who ask such questions. For example, the last page (before the Epilogue) of Simon Singh’s Big Bang: The Origin of the Universe (New York: Harper Collins, 2004) says this, and attributes the origin to St. Augustine. (Singh acknowledges, of course, that Augustine didn’t know anything
What form did the universe take before the Big Bang?
The leading idea is called the “inflationary universe” model. The key assumption of this model is that just before the Big Bang, space was filled with an unstable form of energy , whose nature is not yet known. At some instant, this energy was transformed into the fundamental particles from which arose all the matter we observe today.
