So a year or so ago this question about traveling at light speed and its effect on aging in relation to a view point started swirling around in my head and I came here for answers. I got a few and they kinda made sense. This is one explanation I got "First, the reason its called "relativity" is that you can only talk about "approach the speed of light" relative to some reference point which we take to be "stationary". A person who is "stationary" would observe a person moving close to the speed of light (relative to him) moving and living slower- if he were able to see a clock on that space ship, he would observe it moving slower than his own. Of course people in the ship would not observe any change in themselves. Now this is whats been buggin me, the above may be true, but from a possible vantage/belief point, time started when the universe came into existence and as such the speed at which you travel within it does not change the interval in which the universe has been around and is ticking/creating the one that is traveling at light speed. Yes this interval from when existence started could be broken down into any number of measurements, but none the less its independent of whats going on in it (like light travel or faster). I could see that ones "perception" of time is changing in relation to speed, but non the less the object time line that was started when creation/existence came into being is unaltered. For example lets say creation came into existence 2000 planets ago (I'll use the creation of planets as a measuring of time from its start). Now at 2000 planets time, one planet launches 2 ships into space at different speeds. Lets say one is launched at what we consider light speed and the other at half that. Lets say 1 light year = 2 planets of real time, meaning a planet will be fully formed in 1 light year. So in 1 light year a ship will have reached its stopping point at 2002 planets time, and the other at 2001 planets time. So how does relativity hold up here if this is the real case of time passage. It would seem to me that objects traveling at what ever speed and being viewed from what ever vantage point are ticking at a rate = creation itself. Yes clocks and human aging may slow in relation to light speed but what ever it is that makes up clocks/humans/light all started and exists within a ticking separate from speed. That ticking is the age of when the universe started divided by what ever interval you want to divide it by and to me wouldnt seem to change in relation to how fast its moving. For example the clock experiment moving in a speeding object for X amount of "time" showing to be 10's of billionths of a second different than when it was stationary, is none the less a clock made from materials that started at the creation of time and are ticking at their own interval independent of the "time measuring mechanism" that it is and was ticking at. Again I could see the possibility that a human traveling at light speed would not age visually and they experienced a distortion in their own time experience in relation to those at rest around them, but none the less the energy/matter/creation/light that makes them up to be human is none the less as old as the independent ticking of the universe and speed does not change this objective ticking.
