 2009; Einstein, 2001; Feynman, 1998; Roberts and Schleif, 2007). The theory is "special" because it refers to the special case of inertial motion, where gravity is negligible. It is not surprising that special relativity models human conscious experience. Einstein utilized his own conscious experiences (imagination, thought experiments, diagrams, descriptions, discussions) for the development of his special theory (Hossenfelder, 2015). Einstein in effect analyzed his own conscious experiences to come up with the principles of special relativity. What Einstein actually discovered in his special theory was a model of human conscious experience. Einstein was attempting to describe and explain observed physical reality. One might say that Einstein was successful in this endeavor, as our conscious experience is our observed physical reality. Einstein's General Theory of Relativity Our current understanding of gravity is based on Einstein's general theory of relativity (Einstein, 2001), which is formulated within the framework of classical physics (classical physics refers to all physical theories which are not based on the quantization paradigm-Morin, 2008). There was an inherent limitation to special relativity: the principle of relativity (the general covariance of space-time intervals) could only apply to inertial frames of reference, where gravity is negligible. Consequently, Einstein developed his general theory of relativity to provide a unified theory for both inertial (constant velocity) and non-inertial (accelerated) reference frames (which includes gravitational reference frames). Einstein proposed the principle of general covariance for his special theory of relativity; however, Einstein recognized that the general principle of relativity should also apply to accelerated relative motions (including gravitational), and he used the tool of tensor calculus to extend the special theory's general covariance to all frames, eventually producing the general theory of relativity. The starting point of general relativity is the Equivalence Principle or the Principle of Universality of Free Fall. The weak equivalence principle states that free-falling bodies (influenced only by gravity) at the same initial conditions (position, velocity) have the same acceleration independent of size and composition (Wessen, 2006). The Einsteinian equivalence principle states that the outcome of any non-gravitational experiment in a freely-falling laboratory is independent of the velocity of the laboratory in space-time (Haugen and Lammerzahl, 2001; Pogosyan, 2011). In order to account for these findings in general relativity, Einstein in 1915 redefined several fundamental concepts (such as gravity and inertia) in terms of a new concept of curvature of space-time

It is not surprising that special relativity models human conscious experience. Einstein utilize his own conscious experiences (imagination, think experiment, diagrams, descriptions, discussions) for the development of his particular theory (Hossenfelder, 2015). Einstein in effect analyze his own conscious experience to come up with the principles of special relativity. What Einstein actually discovered in his special hypothesis was a model of human conscious experience. Einstein was attempting to describe and excuse observed physical reality. One might say that Einstein was successful in this endeavor, as our conscious experience is our ascertained physical world. Einstein's General Theory of Relativity Our current understanding of gravity is based on Einstein's general hypothesis of relativity (Einstein, 2001), which is formulated within the framework of classical physics (classical physics refers to all physical theories which are not based on the quantization paradigm - Morin, 2008). There was an inherent limitation to special relativity: the principle of relativity (the general covariance of space - clock time intervals) could only lend oneself to inertial skeletal system of reference, where gravity is negligible. Consequently, Einstein explicate his general theory of relativity to provide a unified hypothesis for both inertial (constant velocity) and non - inertial (accelerated) reference frames (which includes gravitational reference frames). Einstein proposed the principle of general covariance for his special hypothesis of relativity; however, Einstein recognized that the cosmopolitan principle of relativity should also apply to accelerated relative motions (include gravitational), and he used the tool of tensor calculus to carry the special theory's general covariance to all frames, finally producing the general theory of relativity. The starting point of cosmopolitan relativity is the Equivalence Principle or the Principle of Universality of Free Fall. The weak equivalence principle states that loose - falling bodies (charm only by gravity) at the like initial conditions (position, velocity) have the same acceleration independent of size and composition (Wessen, 2006). The Einsteinian equivalence principle states that the outcome of any non - gravitational experiment in a freely - falling lab is independent of the velocity of the testing ground in space - time (Haugen and Lammerzahl, 2001; Pogosyan, 2011). In club to account for these findings in general relativity, Einstein in 1915 redefine several fundamental concepts (such as gravity and inertia) in terms of a fresh concept of curvature of quad - clock time
