This leads to the question of why the formation of matter after the Big Bang resulted in a universe consisting almost entirely of matter, rather than being a half-and-half mixture of matter and antimatter.

In this theory, the remote future of the previous aeons becomes the Big Bang of subsequent aeons.

He especially tried to explain the baryon asymmetry of the universe, being the first scientist to introduce two universes called " sheets ", linked by the Big Bang.

According to the Big Bang model, the Universe expanded from an extremely dense and hot state and continues to expand today.

The Big Bang theory is the prevailing cosmological model that describes the early development of the Universe.

According to the Big Bang theory, the Universe was once in an extremely hot and dense state which expanded rapidly.

According to the most recent measurements and observations, the Big Bang occurred approximately 13. 75 billion years ago, which is thus considered the age of the Universe.

While protons and neutrons combined to form the first atomic nuclei only a few minutes after the Big Bang, it would take thousands of years for electrons to combine with them and create electrically neutral atoms.

The Big Bang is a well-tested scientific theory and is widely accepted within the scientific community.

The core ideas of the Big Bang — the expansion, the early hot state, the formation of helium, and the formation of galaxies — are derived from many observations that are independent from any cosmological model ; these include the abundance of light elements, the cosmic microwave background, large scale structure, and the Hubble diagram for Type Ia supernovae.

Thus, the Big Bang theory cannot and does not provide any explanation for such an initial condition ; rather, it describes and explains the general evolution of the universe going forward from that point on.

Georges Lemaître first proposed what would become the Big Bang theory in what he called his " hypothesis of the primeval atom.

The framework for the Big Bang model relies on Albert Einstein's general relativity and on simplifying assumptions such as homogeneity and isotropy of space.

While the scientific community was once divided between supporters of the Big Bang and those of alternative cosmological models, most scientists became convinced that some version of the Big Bang scenario best fit observations after the discovery of the cosmic microwave background radiation in 1964, and especially when its spectrum ( i. e., the amount of radiation measured at each wavelength ) was found to match that of thermal radiation from a black body.

This singularity is sometimes called " the Big Bang ", but the term can also refer to the early hot, dense phase itself, which can be considered the " birth " of our Universe.

The earliest phases of the Big Bang are subject to much speculation.

A few minutes into the expansion, when the temperature was about a billion ( one thousand million ; 10 < sup > 9 </ sup >; SI prefix giga -) kelvin and the density was about that of air, neutrons combined with protons to form the Universe's deuterium and helium nuclei in a process called Big Bang nucleosynthesis.

The Big Bang theory depends on two major assumptions: the universality of physical laws and the cosmological principle.

Also, general relativity has passed stringent tests on the scale of the Solar System and binary stars while extrapolation to cosmological scales has been validated by the empirical successes of various aspects of the Big Bang theory.

The Big Bang is not an explosion of matter moving outward to fill an empty universe.

An important feature of the Big Bang spacetime is the presence of horizons.

Fred Hoyle is credited with coining the term Big Bang during a 1949 radio broadcast.

These advances made it possible to speculate about the origin of the universe, and allowed scientists to establish the Big Bang Theory as the leading cosmological model.
