Edge of reality is usually called the presence. However, the presence is really human consciousness. Without consciousness there is no past, present, nor future. With consciousness a boundary is formed separating past and future. The past is inner space-time and the future is outer space-time. The past is solely described by true quantum theories while the future is only described by true continuous field theories. In order to formulate a physical theory connecting inner space-time and outer space-time, for example a quantum field theory, then there must be a bridge across this edge of reality called the NOW. This is a boundary separating pure particles from pure field configurations.

The really difficult task is how to describe consciousness as a quantum and simultaneously described it as a continuous field. If the key concept of the former is the mass then the key concept of the latter must be energy. Fortunately, special relativity already bridges these two key concepts together by E=mc. The really easy task is simply to state that c is equal to the dot product of an infinitesimal space-time metric and general absolute acceleration: c=a∙r. This clearly implies that the rate of change of consciousness is the square of lightspeed.
