I think speed is the major element in innovation since we innovate at all times and in all places the problem is commenet react quickly in order to remain in the competitive market
In answer to your question, one has to keep in mind that there is no such thing as space and time but only a space-time fabric. Following this, velocity describes the speed at which an object is travelling though space-time and hence velocity would be the only sense-making answer. Having said that, I stand by what I said in my last post.
