What happened shortly after the big bang?

Answer 1

The Big Bang is the cosmological model of the initial conditions and subsequent development of the Universe that is supported by the most comprehensive and accurate explanations from current scientific evidence and observation.[1][2] As used by cosmologists, the term Big Bang generally refers to the idea that the Universe has expanded from a primordial hot and dense initial condition at some finite time in the past (best available measurements in 2009 suggest that the initial conditions occurred around 13.3 to 13.9 billion years ago[3][4]), and continues to expand to this day.

Georges Lemaître proposed what became known as the Big Bang theory of the origin of the Universe, although he called it his "hypothesis of the primeval atom". The framework for the model relies on Albert Einstein's general relativity and on simplifying assumptions (such as homogeneity and isotropy of space). The governing equations had been formulated by Alexander Friedmann. After Edwin Hubble discovered in 1929 that the distances to far away galaxies were generally proportional to their redshifts, as suggested by Lemaître in 1927, this observation was taken to indicate that all very distant galaxies and clusters have an apparent velocity directly away from our vantage point: the farther away, the higher the apparent velocity.[5] If the distance between galaxy clusters is increasing today, everything must have been closer together in the past. This idea has been considered in detail back in time to extreme densities and temperatures,[6][7][8] and large particle accelerators have been built to experiment on and test such conditions, resulting in significant confirmation of the theory, but these accelerators have limited capabilities to probe into such high energy regimes. Without any evidence associated with the earliest instant of the expansion, 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 since that instant. The observed abundances of the light elements throughout the cosmos closely match the calculated predictions for the formation of these elements from nuclear processes in the rapidly expanding and cooling first minutes of the Universe, as logically and quantitatively detailed according to Big Bang nucleosynthesis

Answer 2

Quantum fluctuation created matter from a singularity. Evidence for this is mounting in dark matter and virtual particles. Refer to the video "A Universe from Nothing" on YouTube for a 1 hour lecture on the subject.

Answer 3

Well, when matter and antimatter collide the destroy each other instantaneously in a flash of light. After the big bang, all there was was matter, antimatter, and energy. For about 15 minutes after the big bang matter and antimatter were colliding and destroying each other and luckily there was a very little more matter than antimatter. a billionth of the amount of matter that started out after the big band was left.

Answer 4

The problem with using the concept of the term Big Bang is that it inadvertently implies an explosive reference. The concept of the Inflationary model of the Universe is to provide an environment in which we can understand its dimensional boundaries. The Big Bang is more a reference to an unfolding evolutionary model of existence in which Space-Time allows for the integration of positive matter. The Big Bang expresses the understanding of an evolving universe from a one dimensional singularity to the traditional fourth dimensional model of our ever-accelerating universe.

To answer the question, a reality of existence came into being in the form of our traditionally understood fourth dimensional universe.

Answer 5

The "Big Bang" Theory states that the Solar system was formed by a singular Explosion centering as the Sun. Yes, most likely the Solar System was formed from a Gigantic Explosion.. But this would also prove that "God" did not create our System. This is why many Ignorant religious people will tell you it did not happen, but, asking them what proof they have will leave them Speechless half the time. But the most important thing is that it happened over Billions of years ago. And it seems it should not even matter anymore.. But of coarse.. Religion has to get in the way of most Scientific Hypothesis and Fact.

Not putting down Religion, I am a man of; "Half-Faith", this is just what life on the planet Earth is like now..

F***ed up if you ask me.

Answer 6

According to Guth, there was a period of unimaginable expansion, far beyond the presently understood limits of relativity.

Answer 7

The universe.
