Mach’s principle has influenced Einstein but the final formulation of general relativity does not follow Mach’s conjecture. Several researches were carried out in last century and many theories are formulated to follow mach’s principle. At present it has been observed that the general relativity can’t provide explanations to many physical phenomenon. Therefore, theories are postulated to modify general relativity. However, it can be seen that many of the old theories which were postulated in past century explains gravity in a better way. But, most of the mainstream physicists at the present time are not aware of those theories.
In this blog we try to list some of the physical theories which were postulated based on Mach’s conjecture.
