:But still there is the question of how to determine the good. Although this measurement is relative to each person, the standard is absolute. Einstein is associated with the term relativity because he was able to recast the equations of physics in terms of an absolute metric - the speed of light. Morality has a similar standard, as simple and ubiquitous as the speed of light. This standard derives from the capacity for empathy and the need to determine what is the best for each person.

Today some physicists are working on a [[quantum theory of gravity]] (the "theory of everything"), including [[string theory]].  Critics increasingly point out that [[string theory]] is largely untestable and unfalsifiable, and thus potentially unscientific under the principles of science advanced by [[Karl Popper]].
