That just goes to show that many of us are over simplifying the "equation", not realizing just how complex this stuff really is. Which is why it may be a while before prediction is possible. Some feel it is extremely unlikely for this reason alone. Daunting it is, I agree.

Another issue, I think many don't realize is just how weak gravity is, as far as forces in the universe go. In fact, as far as the four fundamental forces of the universe go, gravity is by far the weakest by a factor of 10^25 over the next force (weak nuclear force), and 10^38 of the strongest (strong nuclear force). Electromagnetism is 10^36 times stronger, yet we don't see light beams causing earthquakes. Now if THAT does put some perspective on things.... hehehehe

Sometimes it REALLY IS rocket science.
