When gravitation is modelled after real life, there is no such thing as a gravitational shadow. Does this mean that gravitons travel through matter without being scattered?
After more thought, I found that the relaying (e.g. repeating) of gravitons seems to be the source of gravitational time dilation. I mean to say that a process (e.g. a computation) is interrupted by the act of relaying itself -- the relaying of gravitons is the source of gravitational time dilation. This is assuming that everything in the Universe is a computation, that there is a computational speed limit per second, and that internal process is interrupted by external processes (e.g. like interrupts in x86 assembly).
There is an analogy: A juggler can only juggle so many balls per seconds, which be consider to be an internal process. As soon as the jugglers start passing balls in between each other, the internal process is overcome, to the point where the internal juggle rate is next to zero.
