This Is Why We Will Never Know Everything About Our Universe
The universe itself is billions of years old, while the earliest human only first appeared a couple of million years ago on this tiny, insignificant spec of dust in this ever-expanding, never-ending universe which in turn is marching through its own life. But, with the advent of the more evolved human, came science, technology, and innovation; we made fire, built a wheel, carved on stone. With the continuous evolution of human evolved science, technology and philosophy. Even in this relatively short existence of ours, we came to ask many questions that even with the evolution and propagation of philosophy, we have failed to answer yet. Religion was one such alternate theory and it was immediately accepted widely, making human the center of everything and put an almighty creator who was watching over all of this creation of his. People have always had a yearning to know, a craving to understand, their role in this universe.
Our brains may never be well-enough equipped to understand the universe and we are fooling ourselves if we think they will. Why should we expect to be able eventually to understand how the universe originated, evolved, and operates? While human brains are complex and capable of many amazing things, there is not necessarily any match between the complexity of the universe and the complexity of our brains, any more than a dog's brain is capable of understanding every detail of the world of cats and bones, or the dynamics of stick trajectories when thrown. Dogs get by and so do we, but do we have a right to expect that the harder we puzzle over these things the nearer we will get to the truth? Recently I stood in front of a three metre high model of the Ptolemaic universe in the Museum of the History of Science in Florence and I remembered how well that worked as a representation of the motions of the planets until Copernicus and Kepler came along. Nowadays, no element of the theory of giant interlocking cogwheels at work is of any use in understanding the motions of the stars and planets and indeed Ptolemy himself did not argue that the universe really was run by giant cogwheels. Occam's Razor is used to compare two theories and allow us to choose which is more likely to be 'true' but hasn't it become a comfort blanket whenever we are faced with aspects of the universe that seem unutterably complex — string theory for example.
Robert Lawrence Kuhn is the creator, writer and host of " Closer to Truth ," a public television and multimedia program that features the world's leading thinkers exploring humanity's deepest questions. This article is based on a "Closer to Truth" episode produced and directed by Peter Getzels. Kuhn contributed this article to Space. I began bemused. The notion that humanity might be living in an artificial reality — a simulated universe — seemed sophomoric, at best science fiction.
Twice a day, seven days a week, from February to November for the past four years, two researchers have layered themselves with thermal underwear and outerwear, with fleece, flannel, double gloves, double socks, padded overalls and puffy red parkas, mummifying themselves until they look like twin Michelin Men. Then they step outside, trading the warmth and modern conveniences of a science station foosball, fitness center, hour cafeteria for a minusdegree Fahrenheit featureless landscape, flatter than Kansas and one of the coldest places on the planet. They trudge in darkness nearly a mile, across a plateau of snow and ice, until they discern, against the backdrop of more stars than any hands-in-pocket backyard observer has ever seen, the silhouette of the giant disk of the South Pole Telescope, where they join a global effort to solve possibly the greatest riddle in the universe: what most of it is made of. For thousands of years our species has studied the night sky and wondered if anything else is out there. Galileo trained a new instrument, the telescope, on the heavens and saw objects that no other person had ever seen: hundreds of stars, mountains on the Moon, satellites of Jupiter.
A few years ago, I was asked why I had such a passion for physics. Without much hesitation, I said that my interest was rooted in the need to know the truth about nature. Richard Feynman believed that knowing the truth about something came with understanding how such thing worked. Once you understand how something works, only then can you know the truth about it. He compared nature to a chess game played by the gods. But how can we tell that we know the rules of the game?
