Today some physicists are working on hypothesizing how general relativity might have related to the other three forces of nature during the first fraction of a second of the [[Big bang]]. Two of the more commonly studied attempts are [[string theory]] and [[loop quantum gravity]], but they have been complete failures.  Critics increasingly point out that [[string theory]] and [[loop quantum gravity]] are largely untestable and unfalsifiable, and thus potentially unscientific under the principles of science advanced by [[Karl Popper]].<ref>See, for example, ''Not Even Wrong'', by Peter Woit</ref>.

Today some physicists are working on reconciling general relativity with [[quantum mechanics]], and determining how gravity fits with the three subatomic forces of nature (the "theory of everything").
