I don't have a physics background so be as generous as you like in assuming my ignorance. I am studying philosophy and, currently, the idea of identity existing through time. I have an argument that suggests identity can't exist through time because time is a property of objects that changes, thus, making the objects no longer identical. To get a better understanding of my own argument, I need a better understanding of time. Time is a 4th dimension with respect to space. Can I treat time in a way similar to how I treat space. For instance, an object can't exist in two places at once because of spacial limitations. Can I assume time and space are attached in such a way as you could use coordinates to describe them (space x,y,z, at time "t")?'
