Earth's End Might be Near

A new computer simulation indicates that there is a very slight possibility that some of our solar system's planets orbits might vary enough to cause a catastrophic impact with Earth. There is a 1% change that Mercury's orbit might be elongated to the point where its orbit around the Sun might cross that of Venus' orbit in which case Mercury would be sling-shot out of the solar system or possibly collide with Earth. However, this event wouldn't take place for a couple billion years meaning there is no chance that we would experience such an event. In a less likely scenario, there could be a total destabilization of  the inner solar system leading to a possible collision between Mars, Venus, or Mercury with Earth.
