If we live in a 4 dimensional universe, doesn't it only make sense that object which exist in it, exist in all 4 dimensions? I think, a majority of people think of time as a separate dimension from the 3 of space. That is to say, a ball, floating in space affects all 4 dimensions, 3 of space and the one of time. Too often we only think of the 3 - we paint a static picture. Couldn't "gravity" just be the effect of differences in time affecting objects? That is to say - if 2 objects were floating in space, wouldn't the differences in time make them start moving toward each other? If ball A and ball B were floating in space like so: A B Ball A would experience slower time on the side which is closest to ball B. And ball be would experience slower time on the side which is closest to ball A. Wouldn't that make them accelerate toward one another, thus giving the illusion that they are "attracted" to each other? I think there's a general consensus that gravity creates changes in time, what if we got it all backwards, what if it's time that creates the appearance of gravity?
