    The Big Bang did not start at a singularity, and continue at ever increasing speed. 

    Like everything else in nature, large or small, it is a continuum that follows a Sinusoidal Wave, not a straight line. 

    The Big Bang occurred when time was at a peak/ bottom of a Sinusoidal Wave. The increasing expansion is the Sinusoidal Wave increasing in steepness. 

    This sinusoidal Wave is so huge in terms of time and space, that we do not have a full comprehension of it. The 'Big Bang' is a suitable handle on it.

    Yes. In that it's a real theory with gaps and holes and quite a few "you gotta me $#!ttin' me"'s. Since there's nobody around to corroborate the theory, .... But that's what makes science both more accurate by the day, and fun.

    Yes. It did begin with a big bang but some people have said it could have expanded and contracted back before. We could be in a cycle of big bangs and big contractions.

    There is a probabilistic problem with the idea that the Big Bang happened.  Time is eternal and there can be random fluctuations in the vacuum causing Big Bang-like conditions, and since there's an infinite "amount" of time during which that can happen, the chances that we are within an easily measurable distance of the real Big Bang are zero.  I personally suspect that the Big Bang was an event following an antimatter Universe when time ran backwards, but it may not have occurred at all.

    Yes, the big bang is for real. 

    Yes, the universe had a beginning.

    3 degees K microwave radiation look it up

    "Big Bang" (in this context) is the nickname of a theory that explains the effect of expanding space on the energy content of the universe:

    Same amount of energy + more space to spread it out = energy density goes down with time

    (= the universe "cools" with time)

    It's use, as a scientific tool, is to explain how the universe could have behaved in the past: the further back you go, in time, the hotter was the universe.

    At various critical temperature thresholds, "things" happen.  For example, when the temperature is hotter than 3000 K (roughly 6000 F), electrons cannot orbit protons and the universe is filled with free-moving charged particles (unbound electrons and protons). Such a mixture is opaque - it intercepts all photons of light.

    When the temperature is below 3000 K, electrons can bind with protons to form neutral atoms. The universe is transparent.  The transition between the two states (from above 3000 K to below 3000 K) marks the moment when all the light of the universe got released (what we now observe as the Cosmic Microwave Background radiation).

    The Big Bang theory does NOT pretend that the universe had a start. That is because there is a point (in time) when the temperature would have been so high (yet, not infinite) that we fail to understand what happens above that temperature.  THAT is the first moment of the Big Bang (meaning, the first moment that can be understood, using the theory).  "Before" that moment, we simply do not understand what would go on; we don't even understand how time itself would flow (the energy density would interfere with how we would perceive time).

    The priest who had come up with the concept (1927) and the mathematical model (1930) was convinced that the first moment corresponded to the moment his God created the universe.

    In 1948, the idea was proposed as a formal scientific theory. An opponent of the theory (he was a famous atheist) gave it the awful nickname "Big Bang" because the priest (back in 1927) had used the analogy of an "explosion" in his description.  There is no explosion in the 1948 theory. "The Big Bang" does not exist in the "Big Bang" theory.

    Was there an explosion "before" the initial moment covered by the theory? Who knows. The theory itself cannot go there. The theory is silent about anything that falls "before".

    Our (pocket , Big Bang ) universe did -- beyond that we do not know and cannot comprehend .

    Well it is the best idea we can come up with

    Theories are only used when guesstimates are the best we can do

    I don't know about you, but I wasn't there !

    The big bang  is real. turn on TV, 1 $% is from the Big bang.
