The way I always saw it was like this. Light is energy moving at such a great speed that it never even has the chance to interact with anything long enough to either accelerate or decelerate it in a vacuum. The only place that this does not hold true is beyond the event horizon, where it is trapped in a never ending free fall around a singularity. Of course to the light, it is just following a straight line as it always does.

Well, whether that's what's "really meant" by it or not, did it not get the point I was trying to make across? And if the planet was moving at a different velocity than Earth, wouldn't the difference of velocity bring some sort of time dilation into effect (no matter by how big or how small). I'm still relatively new to a lot of this btw, so you will have to pardon any ignorance on my part. I am here to discuss and debate things, thus, I am here to learn more.

How can anything change state in a universe in which all motion is prohibited? The point is that he would never know, because his only reference for time is his own sleep/wake cycle, just like our only reference of time on the surface is the apparent motion of the heavens above us. If we were to travel to another world in another solar system, our only reference of time there would be the same, only from that planet's frame of reference to the apparent motions of the heavens above it. It's all really just relative anyway, isn't it?

The question was can there ever be "zero time". My answer to that question was I believe that the only way there could ever be "zero time" is if there was 100% arrest of all motion universe wide. This would include arrest of motion for everything, completely frozen, nothing moving anywhere. Under that scenario, as unlikely as it is, there would be "zero time". It is my understanding of time that we do measure it, as you saw, on periodic motion. I'm not sure how time could ever be measured in any other way. Everything is always in motion whether you notice it or not, and it is all relative to the observer. On that note, here is a fun thought experiment I had a couple of weeks ago: Say a miner gets trapped in a mine shaft. He has absolutely no source of natural light down there (but he does have a flashlight the operates without batteries), and absolutely no communication at all to the outside world. He also isn't wearing a watch. The miner, assuming he can somehow keep himself alive down there, decides that he'll keep track of the amount of time he's been down there based off of his usual sleep cycle. He knows that he's usually tired and asleep by 9, and awake and ready for the day by 5. So, he waits it out til he falls asleep, and then when he wakes up again he makes a mark on the wall. He's been down there for what he perceives to have been one night. He does this over and over again, ticking off each new day as he wakes up. However the problem is, there is no way for him to know for sure if his system is accurate or not relative to time on the surface. He may think it is, but with no reference of time on the surface, his "days" could be off by a few days, a few weeks, a few years.... there is just no way for him to know for certain. Therefore, his only reference of time is sleeping and then waking again. For all he knows, he could have dozed off for ten minutes and awoke thinking it was all night. (I mean really, do YOU know how much time has passed for you between sleeping and waking without referencing something that will tell you).

How can there be decay if there is no motion anywhere universe wide. No object anywhere, not even a single particle or molecule, would be in motion.

If nothing were moving anywhere in the entire universe, how would you know that any time has moved at all? I can't see that you would. When you start to move again you'll be picking up exactly where you left off. No time lost.

I think that the only time zero time would be possible is if there was 100% arrest of all motion universe wide, for if even one single thing was moving, it would be impossible to tell if it was that one thing moving, or everything else moving around it, and movement is time.

Simple as this: something can't be nothing nothing can't be something
