Interesting idea. This could explain how a gravitational
force is able to pull rather than push, and it would mean gravitational
wells are created by differences in time... time being the variable factor in the fabric of space-time. Time dilation (caused by mass) naturally causes mass to be drawn toward mass. Is this what you mean by time dilation causing gravity?
I haven't found a link for this yet, but an experiment was done several years ago in Russia where an object was suspended in a vacuum and the temp was dropped to just above absolute zero. The object became lighter as the internal activity of the object slowed down. Some of that motion was transferred into a spin of the object itself, but it was the object becoming lighter that I thought was interesting... it suggested gravity could be a function of activity at the atomic level.
Mass displacing space as being the cause of gravity never made much sense to me, because empty space can't be displaced... space can be occupied, but (by definition) it's not displaced.
