Teleology - the explanation of something happening, not as "caused by something", but rather as happening "in order to reach some objective" has been avoided by science at all costs, ever since Galileo and probably a while before that. Science has choosen the "cause and effect" paradigm, against Aristotle's "final cause" . But ever since special relativity, and more so following recent discoveries in particle physics and the development of new paradigms in Chaos theory and Evolutionary Algorithms and Emergence theory, this simplified paradigm of forward-only time, as well as the simplified Darwinian evolutionary "survival of the fittest" theory is begging for an update. In the field of evolution for example, it is clear that simple environmental survival is not the complete answer. Even though un-natural selection IS the way for man (and woman) to create blue parakeets, or better wheat, still, "natural selection" is not the only way in which the kingdom of nature evolves.
As proven in recent discoveries in the field of Genetics, extra-genetic evolution exists, including new extensions to Baldwin Effect. All this is not to say that evolution does not explain how we (people and the surroundings) came to be what we are, but rather to point out that it can be useful to change the point of view on the same known phenomena of the world (commonly called science), and look at it from the other side - the future.
b. Considering future certainty (or: Tracing reality in retrospective):
The science of uncertainty - is the basis for most of science today. The field of statistics deals with the uncertain, and brings about the paradigm of "the law of large systems". Entropy, one of the first discoveries of the study of thermodynamics, is essential to understanding the universe according to science. According to research and calculations, heat - or "untapped energy" will always be lost from any system. So that within time the whole universe is cooling down. This is not just an interesting fact, it is a running assumption, on which much of "hardcore" science relies, and it has an extreme affect on today's philosophy and pessimistic mindset.
