E=mc^2 is the simplified form of an equation given to us by Albert Einstein to describe the relationship between energy and mass. Translated into words, it says the amount of change (E) that we may expect a material subject to be able to produce is directly proportional to a it's mass (m) and the square of the speed of light (c^2). It is certainly a very useful formula; however, in order for it to work, the subject of the equation must have the property of mass. But what about things which have no mass - things like space, for example?(adsbygoogle = window.adsbygoogle || []).push({});

The motion of a substance which has no mass would still require the subject to displace whatever lies in front of it and this change would certainly take an instance of time (t). Mr. Einstein's equation may be accurate, but it is incomplete. It addresses only the special case of subjects with the attribute of mass. I wonder if there is an equation which addresses both material and ethereal substances. I wonder if the additional terms that such a formula would require might finally resolve the issue of that pesky imaginary number X=sqrt (-1)
