Ken, I already explained earlier that an eternal singularity CANNOT expand, since matter/energy in an atemporal state CANNOT change. Expansion is a form of change, and cannot happen unless there somehow exists an outside force to act upon it. The force cannot be internal because it would not have been eternally in the form of a singularity but rather temporarily in the form of a singularity. (I.E. it wouldn't have existed for eternity past.) To argue otherwise is absurdity. And as absurdity is irrational by default, then the universe did not eternally pre-exist as a singularity without any external force to act upon it. For this reason, if the universe eternally existed as a singularity, we wouldn't be here.
This is logic, Kenny. The explanation is, once again, provided.
And please forgive Daniel for presenting an inaccurate version of the Kalam Cosmological Argument.
Rick pointed out Daniel's unintended mistake, and then Daniel apologized.

I just wanted to fix something you said, so Kenny won't be confused about what you meant.
We can also conclude that everything that exists begins to exist must have a cause, because this is what we observe from the universe around us, since the universe expanded from the singularity it must have a cause. The cause cannot be nothing because nothing is just well.......nothing and nothing doesn't cause anything, so the singularity must have an external cause.
It's only things that begin to exist that have a cause. Because if God exists, he doesn't have a cause. I was trying to explain this to my son a little while back.
Thanks for the clarification Rick, my mistake.
If you're going to try to answer the cosmological argument, it's better if you answer this version instead of Daniel's unintended mistake:
1) Everything that
begins to exist has a cause.
2) The universe began to exist.
3) [therefore]
∴, the universe has a cause.
(Showing off the "therefore" symbol above. :3)
As for the matter of the Hubble Expansion Rate: It's the rate at which the universe expands. If I remember correctly, if the expansion rate is above 0, then the universe had a beginnin'. Guess what? The expansion rate is above 0. ;3
As for the problem with the universe contracting: Uh, yeah... it's thought by cosmologists that there's this thing called dark energy which is basically a form of "repulsive gravity" (I.E. it's like gravity but it pushes things away from one another.). This is their attempt at explaining an observed phenomenon: why the universe is expanding so rapidly [clusters of galaxies are spreading further and further away from one another] to the point where it's veering towards eventual heat death AKA "maximum entropy", which will be the result of the 2nd law of thermodynamics in action.
The 2nd Law of Thermodynamics is that entropy of an isolated system never decreases, because isolated systems always evolve toward thermodynamic equilibrium, which is maximum entropy. Entropy is a measure of unavailable energy in a closed thermodynamic system, AKA a measure of disorder within said system.

When referring to the universe, Entropy refers to the degradation of the matter and energy in the universe to an ultimate state of inert uniformity.
