In reply to the discussion: Alan Alda poses question in new contest for scientists: What is time? [View all]Separation
(1,975 posts)33. Saw an interesting documentary on time and relativity
The big example they were talking about was the sun. Our planet has an orbital path based on the sun. Light from the sun takes aproximately 7 seconds to get here. So does is our orbit based on the sun from 7 seconds ago or the sun as it sits 7 seconds from now, and is that an example of time travel? It was way higher than my educational paygrade, but still interesting to watch.
