In the emerging picture of mankind in the universe, the future (if it exists) will surely entail discoveries about space and time which will open up whole new perspectives in the relationship between mankind, mind, and the uni-verse.... But what is now? There is no such thing in physics; it is not even clear that ‘now' could ever be described, let alone explained, in terms of physics.... Notions such as ‘the past,' ‘the present' and ‘the future' seem to be more linguistic than physical.... There is no universal now, but only a personal one-a ‘here and now.' This strongly suggests that we look to the mind, rather than to the physical world, as the origin of the division of time into past, present, and future....There is none of this in physics.... No physical experiment has ever been performed to detect the passage of time. As soon as the objective world of reality is considered, the passage of time disappears like a ghost into the night.
Paul Davies
An explanation of a phenomenon is regarded, apparently instinctively, as the most general possible when it is a mechanical explanation. The "mechanism" of the process is the ultimate goal of experiment. Now this mechanism in general lies beyond the range of the senses; either by reason of their limitations, as in the case of the atomic structure of matter, or by the very nature of the supposed mechanism, as in the theory of the ether. The only way to bridge the gap between the machinery of the physical process and the world of sense-impressions is to think out some consequence of that mechanism. This we will call the hypothesis. The hypothesis, resting still on the mechanical basis, is yet beyond the range of direct experimental investigation; but if, by mathematical reasoning, a consequence of the hypothesis can be deduced, this will often lie within the range of experimental inquiry, and thus a test of the soundness of the original mechanical conception may be instituted.
