peacefulpete, in saying that our earth and solar system are in no danger of being destroyed I was quoting from the article which I referenced.
The some/all the planets themselves might survive, but life would not. It doesn't really matter because our sun will be far too hot by then for water to exist here anyway. The article is making a point of the scale of the distances between solid matter, it is also making clear that the cosmic chaos will leaving everything in a state of flux. Consider how even the changes in solar winds as a system passes through bands of dust completely changes the climate potential. Our system as it currently is is on a blades edge. Just the small influence of general relativity upon mercury's orbit (gravity effect from sun) is predicted to alter its path sufficiently to disrupt neighboring planets (us) in the distant future. Any of these scenarios are projected out many millions of years away and likely to be mute points because we as a species will have moved on or passed away. The present danger to the earth's delicate climate is us ourselves or a rogue asteroid.
