Why of course. Within the physical unverse everything is always changing. From on emoment to the next nothing stays the same. With our limited ability to see things as they are, we are fooled into thinking that there are things that don't change. I am not the person I was when I started to type this post. I have new thoughts and ideas I didn't have that brief time ago. My body has changed: cells have died, new ones created. To my wife who is sitting behind me I appear the same. But I am not. Nor is she. Both of us are closer to death. The chemical balance (or imbalance) of my cells and is constantly changing; even the quarks and gluons are dancing to new tunes and changing partners every second. If, as some here think, we are nothing but chemical reactions in a body bag, we are never at rest, never static and unchanging. And it is thus in all things in the universe.
We are transitory constructs of whatever is smaller and more fundamental than our quantum parts. We are not Real in the sense that we exist in any permanent sense. We exist only in the context of what we and others perceive. Do the rocks, trees and ocean know we exist? Are we real to them? Probalby not. As I said above what is Real is only that which does not change.
