One, You can't say something is impossible just because it hasn't happend yet. Two, We don't know how old the universe is. Three, we don't know how old it will get.

Just because you want it to be so, doesn't make it so. The fact of the matter is, that's what seems to be happening. If our observations are showing something that the laws of phsyics say can't happen, then either the observations are inncorrect or the laws need to be modified to explain them. Like I said before science changes and grows as we learn more. Phsyics can't explain everything, therefore it's not 100% complete, there is room for emprovment.

I did explain before why this force wouldn't manfest itself untill later in the development of the universe, the matter wasn't far enough away yet. In my hypothesis I suggested that gravity had two sides and they were based on the distance between matter. I'm not saying that's right, but it did answer your question on why it hadn't happened earlier.

Oh and before we found that it wasn't happening the universe could easily be decelerating! Just because it's not yet, why do you assume that it has to do it right this minute? How do you know that the universe isn't still in it's begining stages? Even though it's billions of years old how do you know it won't be around for tens of trillions of years more?

Also if you define void outside the universe as I have then the universe is expanding at the speed of light.
