For me, it boils down to this: 1.5 centimeters a year equals 9,300 miles in a billion years.

... which is really just noise compared to the size of the Solar System. It does reinforce the concept that nothing stays fixed. There is always change.

It is also interesting that the Solar System rotation within the Milky Way wobbles at a periodic rate. We pass through the plane of the galaxy roughly every 37 million years or so. Impact craters recorded worldwide show correlations with the 37 million year-cycle of these journeys through the galactic plane – including the vast impact craters thought to have put an end to the dinosaurs two cycles ago.

Just food for thought since they are a long way from figuring this stuff out.

The Earth is 92.some million miles from the sun. One mile is equal to 160934.4 centimeters.
OMG! WE’RE ALL GOING TO DIE!
