Time dilation only happens if you are watching someone else moving very fast i.e. close to the velocity of light that is 186,000 miles per SECOND. Time always passes normally for the observer
Dudley asked the Naked Scientists: As time slows down relative to speed, would the world go at a faster rate if it were to stop? It orbits the sun at about 82000 miles per day. Would time pass slower or faster on another planet, or in another galaxy. Or is time something that man has invented ?Or is it part of the space-time continuum which I find difficult to understand.What do you think?
It's 'c' that creates a 'time dilation' and a 'length contraction', the fact that it is invariant.
