So...when time slows down in space, the universe is not as old as earth?
OK, I am a visual learner and first had to find out about quarks. Then I wanted to see if they had photographed a molecule. Yup. 2013. Time for me stopped in 2012 when my kid was in Afghanistan. Restarting the clock is super hard. I’m stuck in that time warp. Good thing I was on earth though, can’t imagine time going any slower.
Time for a particular object slows down relative to an object that is stationary(like a timer on a fast moving airplane relative to a timer on the ground previously synchronized together before the airplane and the plane’s timer left the ground). It’s not about time slowing down in space it’s about time slowing down for a particular object the faster it gets to the speed of light. A ship may go near the speed of light to Alpha Centauri and back in over 8 years our time. Yet for the travelers on the ship, they will have experienced only several months flight time. One’s spouse who is 2 years older than the other goes on such a trip but when the spouse come back, one is 6 years older than his or her spouse. That is how time works at supra relativistic speeds. The Earth in it’s orbit about the sun experiences it’s own time distortions relative to the rest of the universe and the sun itself is in motion carrying it’s planets with it. We can only speak of time as we experience it here on Earth but we do know that time is not a fixed constant relative to other objects in motion. Gravity is said to affect time as well as the rate of motion and the mass of an object. We have to make synchronal time adjustments for example when we attempt to program on going space probes for maneuvers as their on board clocks may slow down relative to us(not that their clocks are actually slowing down, just that their faster velocities relative to us cause experiential time to slow incrementally over time relative to Earth bound observers).
