Panpsychism, in the general sense of everything in nature has some sort of consciousness (and I know, this is highly dependent on the way we define consciousness, but I want to talk about panpsychism in the general term, so, if it's ok, I'll let the answers to determine what definition of consciousness is used). Sometimes it's defined as multiple levels of consciousness, sometimes as one consciousness acting "behind" everything.
My question would be, can panpsychism, in any way, have some scientific (/empirical) testable meaning? In other words, is this line of thought worth exploring in science?
I know panpsychism is mostly metaphysical, and the idea of metaphysical to be tested in the science realms is often rejected, but maybe some aspects of it can be.
