The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [1] The notion of an expanding universe was first scientifically originated by physicist Alexander Friedmann in 1922 with the mathematical derivation of the Friedmann equations.
The stuff that was in the hole has now become the hill, so it all perfectly balances out. This is the principle behind what happened at the beginning of the universe. When the Big Bang produced a massive amount of positive energy, it simultaneously produced the same amount of negative energy. In this way, the positive and the negative add up to ...
Some cosmologists believe it to be possible that something (e.g., the universe) may come to exist spontaneously from nothing. Some mathematical models support this idea, and it is growing to become a more prevalent explanation among the scientific community for why the Big Bang occurred. [40]
A Universe from Nothing: Why There Is Something Rather than Nothing is a non-fiction book by the physicist Lawrence M. Krauss, initially published on January 10, 2012, by Free Press. It discusses modern cosmogony and its implications for the debate about the existence of God .
Creatio ex nihilo is the doctrine that all matter was created out of nothing by God in an initial or a beginning moment where the cosmos came into existence. [13] [14] The third-century founder of Neoplatonism, Plotinus, argued that the cosmos was instead an emanation from God.
String theory posits that at the beginning of the universe (up to 10 −43 seconds after the Big Bang), the four fundamental forces were once a single fundamental force. According to string theory, every particle in the universe, at its most ultramicroscopic level ( Planck length ), consists of varying combinations of vibrating strings (or ...
Whether that "nothing" was the clouds or the Big Bang or God grabbing everything and throwing it into the universe, they're all very similar and they don't necessarily negate each other as answers.
The CMB is landmark evidence of the Big Bang theory for the origin of the universe. In the Big Bang cosmological models, during the earliest periods, the universe was filled with an opaque fog of dense, hot plasma of sub-atomic particles. As the universe expanded, this plasma cooled to the point where protons and electrons combined to form ...
