I think if we first understand what 'time' and 'space' really are than rest becomes easy to understand. To me time is the rate at which things change or its just a measure of change. Everything is changing state, electrons are moving, bodies are moving from one point to another and also the clock moves the same way. The diagrams that explain gravity show 'space' as a 2d plane with planets weighing it down making other small objects come toward it. That's a misleading representation I think in a sense that it depends on weight/gravity. I understand space as a sponge. Heavy objects with huge mass are like a squeezed lump in that sponge effecting space around it. Larger the mass, more it squeezes, more it effects what's around it. When an object moves through space, it effects time as well i.e. rate at which change happens within that object. At very fast speeds, speed of light, it's already moving through space changing space, change within that object is reduced to nothing making time move slow for it. That all I think it is.
