AN EVIDENCE TO SHOW TIME DILATION IS POSSIBLE ....

There are other ways, however, to put his ideas to the test. How do we know Einstein had it right? One experiment in the 1970s provided some pretty strong evidence:

Atomic clocks are extremely accurate clocks that can measure tiny amounts of time—billionths of a second. In 1971, scientists used these clocks to test Einstein's ideas. One atomic clock was set up on the ground, while another was sent around the world on a jet traveling at 600 mph. At the start, both clocks showed exactly the same time.

What happened when the clock flown around the world returned to the spot where the other clock was? As Einstein had predicted in a general way, the clocks no longer showed the same time—the clock on the jet was behind by a few billionths of a second. Why such a small difference? Well, 600 mph is fast but still just the tiniest fraction of the speed of light. To see any significant differences in time, you'd have to be traveling many millions of miles an hour faster. 

One of the issues that concern many people who wish to adopt young-earth creationism as a valid view of earth history is the question of how stars can be seen many millions of light years away if only a few thousand years have passed since they were created. Dr. Russell Humphreys, a previous researcher at ICR, spent years working on this problem and has developed a creationist cosmology that seems to resolve this question.

On the fourth day of creation, how long did it take God to make the stars and bring their light to earth? No time at all, according to clocks here on earth. That is what Humphreys concludes from his new creationist cosmology research. The cosmology presented in his 1994 book, Starlight and Time,¹ had the light getting to earth in a finite amount of time, not instantaneously. The general features of that cosmology—a universe centered upon our galaxy, expansion of space, and gravitational time dilation—still appear to be correct. But Humphreys was never fully satisfied with its details because a) the solution did not provide enough time dilation for nearby stars and galaxies, and b) it was based on a metric—a solution of Einstein’s gravity equations—that was too complex to analyze fully.

A referee for a subsequent relativity paper Humphreys wrote insisted that he derive a new metric to support the paper’s conclusions. After several months of mathematical work, Humphreys found the solution and the Journal of Creation published his results.²The article’s appendix contains the new metric and derivation. In a series of Acts & Facts articles, we will describe qualitatively the implications of this new metric and how it explains the cosmology of the creation events.

The new metric is not complicated, compared to many modern ones. Because it is simple and yet rigorous, it shows a feature of gravitational time dilation that nobody had noticed before. The feature was implicit in many previous metrics, but it had been obscured by the effects of motion. Humphreys calls this feature of time dilation achronicity, or “timelessness.” It causes clocks and all physical processes—hence, time itself—to be completely stopped in a region that could be very large. This is in contrast to the time dilation around a black hole, in which time is completely stopped only at a certain exact distance from its center, at the “event horizon.”³ In his 2008 article, Humphreys showed how this new metric led straightforwardly to achronicity. In the last five pages of the paper, he applied the time dilation achronicity to develop a new creationist cosmology.
