What we “talk about” as objects forms in the first 100ms where we have to discern “Am I looking at properties, or am I looking at an object?”
What objects are as objects likely depends on scaling:
On our human scale, my mug is an object in comparison to the air around it and the liquid within it.
But if I were planet-sized, there would be no mug or water object just the air perhaps. The mug and water would be lost to scale.
On the contrary, change is ongoing.
Continuing with scaling, were I a picosecond timed being that was at the nanometer scale, my mug would not be an object per se. There may be some changes occurring in a particular zone, but they would be happening quickly and have a reality far greater than any “mug-like” thing.
An object must be salient to be an object.
