5 Apr 15 ~QofDay~ Expansion

Why doesn’t the Solar System expand if the whole Universe is expanding?

At this stage in the evolution of the universe, the rate of expansion (if it exists, which it seems likely it might), is so small that on something as small as our solar system the effect is extremely small – below the level of our instruments to accurately measure at this time.

There are so many other things going on in our solar system that the influence of the expansion of the universe is a close approximation to zero (at this time, and at the scale of the lifetimes of human beings) – that may not always be the case, and it seems likely to remain the case for the next few billion years. So not something to worry about at this time.
