If time is slowed for an observer circling the Earth and we put an observer on the earth, sun, center of the milky way and finally the center of the universe then would it be correct to say that time would be moving fastest for the observer at the center of the universe?
If so is it possible that the passing of time becomes infinite and how would matter exist or would only energy be present in such a place?

No. But, in any case you must tell us whose inertial system it is in which you wish to make observations. Every observer will observe that clocks run slower in all other systems moving relative to his own.

Also, how do you define or locate a unique center of the universe? It would depend on the universe model you select, but generally speaking every location in the universe has equal claim to being the center--or you could also say that there is no center of the universe. It is like looking at the surface of a sphere and asking, "Where on that spherical surface is its center?"

Do you mean time passing at an infinite rate? The premise is meaningless in view of response to first question. But, No.

Again the premise is meaningless. But, in any case, there is no place that is any different or special then any other...except for possibilities of certain black holes I suppose.

I appreciate the quick response and please forgive me for being so general I am a layman. On the first question would time move faster at the center of the universe. In my mind the center of the universe would be the center of the big bang because from there everything theoretically originated and so (all things being equal) that point would not be moving in any direction in relation to what came out of the big bang. Now back to my reasoning for the first question I asked. The 1971 time dilatation experiment showed the clocks that traveled eastward were 40 nanoseconds behind the clock on the ground. So my thought is if this experiment was taken farther and a clock was put on the sun, center of the milky way and the center of the big bang then wouldn’t the clock at the center of everything be ahead of the clock at the center of the milky way and the milky way ahead of the sun and the sun the earth. So from the standpoint of someone on Earth the stars would appear to move faster than for the observer at the center of the universe.

Thank you for your patience.
 
Thread 'Can this experiment break Lorentz symmetry?'
1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...
Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...
