What Causes Time Dialation? Why should time slow down in the presence of a gravitational field? This is a fundamental question. It has been described mathematically, but not in an intuitive mechanical sense. I have been working on a neutrino aether theory which may help explain the mechanical reasons why this happens. In my theory, all of "empty" space is actually filled with an ordered checkboard array of matched protons and electrons. I am calling these matched protons/electrons "neutrinos" for lack of any other suitable terminology to describe a dipole binding of proton/electron, but may not actually be the same as what is commonly known or accepted as a neutrino or neutron. In any case, if space were filled with these neutrally charged particles, they would all exhibit an attraction to a strong electrostatic force. My theory postulates that gravity is simply a positive electric charge on the Earth such that the Earth acts as a large positively charged sphere is space. I have many posts discussing the details of how this can work and how the Earth and Moon don't go crashing into each other (search frankli...@yahoo.com). If this is true, then the density of the aether will be higher in a higher gravitational fields due to compression forces. Just like water pressure in the deep sea is higher than on the surface. With this higher density means that any mechanical process from point A to point B will have to traverse more aether particles than it would in a lower density area. The increased number of particle interactions effectively increases the amount of time (in an absolute sense) that it takes for something (like the ticking of an atomic clock) to happen. Thus, clocks in a high gravity field tick slower than one in a lower gravity field. This is a simple and intuitive mechanical explanation that shows that rate that time passes is a function of the local environment.
