Richard: Conceivable on ideal rational reflection, i.e. without logical error, implicit contradiction, or conceptual ignorance (e.g. failing to realize that hand just means fingers etc.)
Conceptual ignorance? Do you have to show such freedom from contradiction, or do your opponents have to show such a contradiction? Either would require you to state the concepts involved in a perfectly logical and complete form. So, what is the physical, precisely? (If it includes QM and GR then there is probably a contradiction.)
