Question: Why is relative and absolute dating a useful tool?

With absolute age dating, scientists determine the absolute age of a rock in millions of years before present rather than just the age of the rock relative to the rock units around it. This information helps geologists develop more precise geological history models for the rocks and regions they study.

How did Einstein prove relativity?

Einstein postulated three ways this theory could be proved. One was by observing the stars during a total solar eclipse. The sun is our closest strong gravitational field. Light traveling from a star through space and passing the suns field would be bent, if Einsteins theory were true.
