It's "Devil's advocate" time, so to speak:

> 1) Where did the stuff come from in the first place?

It was there all the time, same as the Christian belief that God is
eternally existant.  Writing off the begining of time by saying that
God created time and matter is merely begging the question.

> 4) How come the 2nd law of thermodynamics is violated?

Space and time did not exist prior to the "Big Bang" and thus the 2nd
Law of Thermodynamics did not exist.

The mass is finite, not infinite, thus gravity is also finite.  You're
playing games with assumptions here, Bro George.

> 6) With infinite gravity how come the universe is expanding?

See answer to question 5. i.e. gravity is finite because there is a
finite amount of mass.  What hasn't been determined is if the universe
is expanding at the escape velocity of itself.

> 7) Is the universe expanding at a constant speed?

No.  Gravity is slowing the expansion down.

Umm, the uniform distribution of matter and energy, which was observed
earlier this century, is what gave rise to the "Big Bang" theory in the
first place.  It's also why all galaxies appear to be moving away from
us.

The force wasn't infinite, just as matter and gravity aren't infinite.
This is a finite universe we live in.

The Big Bang Theory doesn't answer all the questions about cosmology,
nor does it claim to.  Scientists take "stumpers" as a challenge --
something new to discover.  The Big Bang Theory is also readily
acknowledged as imperfect -- there are observations which apparently
fit the observations.

Scientists make observations, then postulate a theory to explain the
observations.  The theory is then tested by making different
observations and comparing them with what the theory predicts.  If the
observations match the predictions, then people begin to think the
theory is pretty good.  If the observations do not match the
predictions, the theory is thrown out or modified.
