I made four conclusions in the above post, so I?m not sure which you are pointing to.
1. If the universe had a beginning, it cannot be eternal
2. The Big Bang marked the beginning of the universe as we know it
3. Eternity & infinity must reside outside the universe if they exist
4. This model presents fewest problems for both sides in this debate unless you?re a bible literalist.
My post was in reply to one by Pointlessness about the universe being eternal. Since the big bang would negate an eternal universe, I was merely pointing out that eternity and infinity could only be worked into the equation by moving them out of the physical universe. The last sentence, which I presume to be the one you object to, is my opinion about how to best model the cosmos if you don?t want to limit the possibilities. Some people feel more comfortable with known boundaries, so they create safe zones where their thinking will not be challenged. The bible literalists are a perfect example of this.
Most people put up some kind of fence around their thinking that includes certain items and excludes others. It?s how we order our world.
I presume that your model of the cosmos is not the same as the one presented above, but, no doubt, you have one. But it is just a model. Nothing in your model or mine eliminates the possibility that our universe might be nothing more than a terrarium on the desktop of some larger seven legged entity which is trying to seduce its secretary.
Let me know which conclusion troubles you.
