Hey everyone. Let me preface this by saying, I love physics and astronomy, but am by no stretch an expert in either subject. I had a question that I thought someone on this site might be able to answer, I have been looking around the internet, but couldn't find one. So, I understand that The Theory of Relativity, very simply, states that time is relative to our velocity. I also understand that the Earth orbits the sun at roughly 67,000 miles/hour. Now, my understanding is that the sun is essentially motionless in the center of our solar system, and all the planets orbit it. So, my question is, wouldn't the Earth and all of its inhabitants be "aging" much slower than the Sun? Is the Sun a lot older than we think it is? I mean, if time slows the faster you move, and the Earth has always been moving faster than the Sun, then I feel like after a few billion years, the difference in our "time" and the Sun's "time" would have to pretty huge by now. This might be a stupid question, but I would like a legitimate answer.
