Guessing at Numbers and Figures

Science is a representation of the world we live in, a sum of best guesses, an interpretation and explanation (however partial or incomplete) of the stimuli we sense. The models created work on a basis of laws and constants that by their very nature do not change or fluctuate. Theories, however grand or complex, are still limited to our own nuances as a species on the planet; if our senses are limited dimensionally, so too are our contemplations and understandings.

With this said, the BBC has been running a series of programs celebrating the anniversary of Charles Darwin's Origin of Species. I watched the David Attenborough presented feature, and it was an hour packed with great footage, great music and amounted to an all round interesting program. Yet throughout the hour I was thinking, "all this is great, if the models that we are basing these theories on are actually correct". Now, I'm not saying that I don't think Evolution is the best explanation we've got at present (According to The Guardian less than 30% of Britons are convinced), and Mendel's model of genetics is great, but aren't we just playing a giant game of Cluedo? I'll elaborate. We have an end result (the present state of things), and we have a set of laws that co-exist with the end result, and ways of representing this end result (Scientific Knowledge). But are there other laws that would fit equally well that are yet to be discovered? For example, Carol Vorderman could show me several ways of reaching the same conclusion in the Countdown numbers round, and compared to some of the complexities of nature, that analogy is embarrassingly simple.

Did the first life forms 'exist' in four dimensions? If, as animals, we have eventually reached a stage at which we are aware of a concept of time (although in itself this presents all kinds of questions), could future descendants (millenia down the line) ever 'exist' within an additional dimension, one that we cannot sense at present? In the same way that organisms have evolved to sense light, are there other dimensions or stimuli that we at present cannot sense, but in which our current laws and constants do not apply?

One thing we can say with an arrogant certainty; the current state of McVitie's Chocolate HobNobs is a present perfection, and one that we should all enjoy whether or not the current understanding of our universe is satisfactory or not.
