I've given the original poster's theory some thought now. And I've came to the conclusion that we are indeed experiencing the last example that he's shown us. I'm referring to the example where a four-dimensional object is manifesting itself into our world, but appears as a 3-dimensional sphere. All objects around us appear 3-dimensional, but they could really be in fact fourth or even higher dimensional objects. Which leads me to string theory. This is basically saying that the higher dimensional part of all objects are hidden to us. That would further support the theory that at least one of those hidden dimensions is the time of the object, at all other given periods of its of existence.
