The fact that theories change and our measurement of nature improves and more and more facts are found out about the universe and are subsequently revised, peer-reviewed and added into our ever improving understanding of the universe is a good thing. This is why our technology improves so much. If our understanding didn't improve then it would be very difficult to improve our technology by the leaps and bounds that it has in the last few hundred years.

You better be happy that science is self-improving, because if it wasn't we wouldn't be able to have this conversation right now.
