All matter was conglomerated into a singularity - a point with basically no volume but extremely high mass and "infinite" density. Something (which is currently indeterminate by science) made this unstable and the universe began expanding rapidly.
The resulting energies moved the matter apart and resulted in much radiation being formed; the matter which was left over consisted of only the most basic subatomic particles in plasma form for quite some time.
After a very short time, along the order of a microsecond from the start, annihilation of matter-antimatter pairs began, repeating for different types of particle at different time up to about a second after the start.
Following that, the usual cosmic events followed: nuclei collide and form heavier nuclei, radiation is bounced around, and everything cools down enough to allow "normal" things to happen.
It depends, because some might say 'scientists'. But not all scientists believe in this theory. Also, there are those who believe in a similar idea to the Big Bang, but it is not refered to as 'The Big Band Theory.'
Most scientists believe that an infinite dense singularity existed before the incident known as the Big Bang.
The Big Bang theory was proposed (happened) in the middle of the 20th Century.The theory, and the work exploring it, suggest that the Big Bang happened about 13.7 billion years ago.
I believe most scientists would agree that this is not currently known. Some, however, would say that there was no "before" - that time itself started with the Big Bang.
As of yet, there is no majority opinion on that yet. There are various hypothetical models on the origination of the universe, foremost among them several variants on M-theory, but no way to establish a preference for any of these models.
The Big Bang Theory
sikhs do believe in the big bang theory. it was written in the guru granth sahib ji before scientists found out.
by a theory of the BIG BANG explosion and the HELIOCENTRIC theory,that until now is being believe
No, most scientists still believe in it, if that's what you mean.

Yes, scientists still believe in the cell theory today because it is a well-established and widely accepted principle in biology. The cell theory states that all living organisms are composed of cells, and all cells come from pre-existing cells through cell division.

Scientists believe that the scientific theory is the best way to solve the problem statement. just write ideas about scientific theory.
