Perhaps I should be volunteering to the University of Christian Cardiology to isolate the physical properties of the Christian God?
Two immediate problems spring to mind;

- Were such an entity to exist, I feel they would rather pluck their eyes out than offer the wider scientific community the opportunity to search for God shaped entities in reality
Of course, it may be the case that I am simply equivocating the theological definition of 'heart'. If this be the case, what is the Christian definition of the word 'heart'?
