Planetary Orbits not stable over longer time frames

Here's a very interesting story regarding a scientific paper projecting the odds of planetary orbit disruption in our solar system. This is the kind of stuff you don't learn in the school books and is why I regularly check links to science articles. Interesting stuff.

Appararently over long time periods the planetary orbits as we currently know them are not stable, and there are are small percentage chances that some current planets may wobble/evolve into orbits that cross the orbits of other planets - creating the likelihood of planetary collisions within our solar system. Apparently this is the most complex modeling of planetary orbits over long periods attempted.

From the article:

Our solar system has a potentially violent future. New computer simulations reveal a slight chance that a disruption of planetary orbits could lead to a collision of Earth with Mercury, Mars or Venus in the next few billion years.
