Wow. I never thought AiG was that bad off.
Nope, the net energy sum of the universe has been and will be zero. Positive energy constitutes conventional mass-energy and negative energy constitutes the expansion of the universe (as I remember). Therefore there is no difficulty within quantum theory for zero energy to spontaneously produce a large amount of positive energy (mass-energy) and negative energy (that causes it to "inflate" furiously) at the same time. Which is precisely what happened.
Gravity on such small scales isn't as simple as we'd expect, fullstop. I don't know much more beyond that.
Dark matter concentrations and initial anisotropies in the universe would have caused local matter clumping. The study of the initial universe's anisotropies in the CMB (cosmic microwave background) has been a very important source of information for this. Taking the scale of the whole universe as macroscopic and the scale of individual galaxies as microscopic, on a microscopic scale matter clumps together while on a macroscopic scale the microscopic clumps of matter are going outwards. That is both self-consistent and consistent with experimental observations.
Note "some", not "all". Besides, it is experimentally verified that some reactions (proton to antipion, if I remember - I barely do after all this while. Must go read heavily Buddhist-ified quantum mechanics book to refresh while praying I'll be smart enough to write a heavily Christ-ified quantum mechanics book someday) that produce matter from antimatter do not follow the T (time) symmetry. Basically if one runs the reactions forward in time an excess of matter results while if one runs the reactions backward in time an excess of what we call antimatter results. (I say "what we call" because had we lived in such a universe we would call matter antimatter and antimatter matter, but that doesn't really matter much to this matter anyway.
)
What experiments, specifically?
Mmm? Steady state theories have been out of vogue for the past 50 years. Note that this does not actually disprove the Big Bang, it just disproves oscillatory Big Bang models, which is perfectly fine for the TE. Also, there is experimentally verified dark matter existence which might (although it might not, either) balance the scales properly.
Where is everybody? Gazillions of light-years away from us, obviously. Go google the Drake equation and see what the odds are. If there are any civilizations more than 200 light years away from us they're probably asking the same thing - and that's spitting distance in galactic terms.
I wonder if Dr. Humphreys proofreads AiG's cosmology?
What arbitrary assumptions? I hope you don't mean arbitrary parameters.
Maharg: Your balloon example is a standard example and is in fact used by YECs as well - Dr. Humphreys in particular in Starlight and Time. You can't go too far wrong with it. Just be clear that:
as two dots move away from each other
on a two-dimensional surface
embedded in an expanding three-dimensional object,
so two galaxies move away from each other
in three-dimensional space
embedded in expanding four-dimensional spacetime.
If you think going 4-D is going to be a bit too much you can always cut it.
1. Missing Origin. The Big Bang theory assumes an original concentration of energy. Where did this energy come from? Astronomers sometimes speak of origin from a "quantum mechanical fluctuation within a vacuum." However, an energy source is still needed. Actually, there is no secular origin theory, since every idea is based on preexisting matter or energy.

2. Missing Fuse. What ignited the Big Bang? The mass concentration proposed in this theory would remain forever as a universal black hole. Gravity would prevent it from expanding outward.

3. Missing Star Formation. No natural way has been found to explain the formation of planets, stars, and galaxies. An explosion should produce, at best, an outward spray of gas and radiation. This gas should continue expanding, not form intricate planets, stars, and entire galaxies.

4. Missing Antimatter. Some versions of the Big Bang theory require an equal production of matter and antimatter. However, only small traces of antimatter (positrons, antiprotons) are found in space.
Note "some", not "all". Besides, it is experimentally verified that some reactions (proton to antipion, if I remember - I barely do after all this while. Must go read heavily Buddhist-ified quantum mechanics book to refresh while praying I'll be smart enough to write a heavily Christ-ified quantum mechanics book someday) that produce matter from antimatter do not follow the T (time) symmetry.

(I say "what we call" because had we lived in such a universe we would call matter antimatter and antimatter matter, but that doesn't really matter much to this matter anyway.
5. Missing Time. Some experiments indicate that the universe may be young, on the order of 10,000 years old. If true, then there is not sufficient time for the consequences of the Big Bang to unfold. A short time span would not allow for the gradual evolution of the earth, heavens, and mankind.
What experiments, specifically?
6. Missing Mass. Many scientists assume that the universe will eventually stop expanding and begin to collapse inward. Then it will again explode, and repeat its oscillating type of perpetual motion. This idea is an effort to avoid an origin and destiny for the universe. For oscillation to occur, the universe must have a certain density or distribution of mass. So far, measurements of the mass density are a hundred times smaller than expected. The universe does not appear to be oscillating. The necessary mass is "missing."
Mmm? Steady state theories have been out of vogue for the past 50 years. Note that this does not actually disprove the Big Bang, it just disproves oscillatory Big Bang models, which is perfectly fine for the TE. Also, there is experimentally verified dark matter existence which might (although it might not, either) balance the scales properly.
7. Missing Life. In an evolving universe, life should have developed everywhere. Space should be filled with radio signals from intelligent life forms. Where is everybody?

From what I've read, even those who promote the Big Bang recognise it is based on a number of arbitrary assumptions.
