This Is Why We Will Never Know Everything About Our Universe
Various long-exposure campaigns, like the Hubble eXtreme Deep Field XDF shown here, have revealed thousands of galaxies in a volume of the Universe that represents a fraction of a millionth of the sky. But even with all the power of Hubble, and all the magnification of gravitational lensing, there are still galaxies out there beyond what we are capable of seeing, as well as information beyond that which we have no known way of gathering. In terms of ambition, it's hard to ask for more than to know absolutely everything there is to know about the Universe. That's the ultimate scientific dream: not just to understand the laws that govern reality as fully and deeply as possible, but to understand how every single particle in existence behaved from the moment of the Universe's birth up through the present day. But this dream isn't necessarily one we're capable of realizing, even with arbitrarily good equipment and ideal observational methods.
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.
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.
There are no uncharted lands waiting for ships to find their shores, and few if any untasted fruits waiting for human lips.

The Known Universe by AMNH
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. Since then we have found more than planets around other stars, billion stars in our galaxy, hundreds of billions of galaxies beyond our own, even the faint radiation that is the echo of the Big Bang. Now scientists think that even this extravagant census of the universe might be as out-of-date as the five-planet cosmos that Galileo inherited from the ancients.
