E=mc^2 (Rest energy equation)
E/c^2=m=0 (To prove)
We know that c^2 is a constant so if we want to prove m=0, we will have to prove E=0. Let's take another formula:
E=hv
So, we can prove it by this equation. As we are taking the photon to be at rest, there is no frequency at rest. It will have no frequency. So, we will get E=h*0=0. Putting it in the previous equation, we get m=0. That's how I proved it. But today I thought that in this way everything at rest will vanish from the universe.
Okay let's take this experiment. Suppose we stop every matter in the universe. Then everything will vanish according to the above proof. So, anybody outside the universe will never be able to sense that there's a thing like time.
And this state of stopping everything can be achieved by stopping time. Everything will come to rest and will vanish from the universe.
Hence, we can derive that mass and motion can only exist when time exists or conversely time only exists when mass and motion exist. If time exists and mass and motion don't exist, then we can never feel time. We get that feeling when anything comes into motion. So, both are true.

I agree with your concept that time cannot exist without motion completely - it fits my gut sense. I can't accept the mathmatics yet, until you show me a photon that is not moving. Another way of looking at it, without anything at all moving, I'm convinced time would not exist, because there would be no way of differentiating 2 successive measurements (everything would be in the same spot/state).
What logically follows is another thought experiment. What if the 'fabric/surface' of our spacetime is actually moving at the speed of light (C)? Could that explain why a photon's rest mass is 0? Because it is at 'relative rest' to the fabric (it would also explain why 'C' is such a special velocity, when relativity says no particular reference frame is special)? Could it also explain why mass can't reach the speed of light, i.e. it must for some reason, always have some velocity difference relative to the fabric, or it's mass becomes non-existant/unmeasureable/zero/infinite, i.e. pure energy (don't forget the real ramifications of re-normalization here)?
