If an event is localized and the observer is also considered to be localized then it will take time to perceive the event. This is the scenario assumed by Einstein in his theory of relativity. If either the event or the observer is universal then this limitation does not exist.

**It takes time to perceive an event only when the event and the observer are localized.**

An event is universal if it is the same all over the universe. This is the case with the universal properties, such as, the substance, its extents (space) and duration (time), and with the universal laws, such as, the law of gravity.

**A universal event consists of universal properties and laws.**

An observer is universal if it is not bounded by assumptions and fixed ideas. It views things and changes just as they are without any filters.

**A universal observer is unbounded in its view of things as they are.**

As science is objective it may be identified with the universal observer. We may look at Einstein’s theory of relativity from the viewpoint of this universal scientific observer. When we do that we notice that Einstein’s observer is attached to the inertial frame of reference. It is, therefore, subject to the properties of that frame. The most mysterious property of that frame is INERTIA.

**Einstein’s observer is viewing speed through the filter of inertia and not aware of it.**

To understand Einstein’s theory of relativity completely one needs to observe how inertia of objects influences their speed.

When two cosmic objects are revolving around each other, they are rotating with the same angular velocity around their common center of mass. According to the law of lever, the more massive object is closer to the center of mass and moving more slowly. Thus, Earth’s speed is slower than the speed of the moon but faster than the speed of the sun. The object at the center of a galaxy is expected to have the least speed and the greatest mass or inertia.

**The greater is the inertia of a cosmic object, the lesser is its speed.**

From the perspective of “continuum of substance” an object is a quantized pulse traveling in the sea of electromagnetic substance. The propagation of this pulse is balanced by its inertia. The resulting motion appears as the speed of the pulse. Therefore, this speed is an inherent property of the object.

**This speed is inherent to the object.**

We may thereby assume that an object with infinite inertia will be at absolute rest. As inertia decreases speed increasingly manifests itself in its absolute value

**This speed is also absolute in value.**

Thus the mystery of Einstein’s observer may be resolved in terms of the inherent inertia and inhernt speed of the inertial frame of reference.

**Speed may not be assigned arbitrarily to an inertial frame without taking its inertia into account.**
