When the Universe Became Fuzzy
by Lambert Dolphin Lambert Dolphin
exert: "Physicists like to keep things simple: to do as little work as possible, they follow "Occam's Razor"7 and have a sense of elegance and beauty about nature. Therefore simple theories are to be preferred to complex theories-and if possible a Grand Unified Theory (GUT) would be wonderful to discover. GUTs attempt to link together the four forces of physics8 and the fundamental constants - c, the velocity of light; e, the charge on the electron; h, Planck's constant; and, G, the gravitational constant. When one brings quantum mechanics into attempts to unify the laws of physics, Planck's constant is found to define the "fuzziness," or the "grain size" of the universe. Thus the smallest meaningful length is (Gh/c3)1/2 = 10-35 meters. The smallest time increment of time is the Planck time, 10-42 seconds, the Planck mass, (hc/G2)1/2 = 1019 Gev, etc.
Quantum mechanics furthermore has revealed that attempts to make measurements-for instance, on an atom-would disturb the atom such that precision in one type of measurement automatically meant fuzziness in another parameter.
If one wanted to locate an electron's location accurately by means of a measuring apparatus, the apparatus disturbed the environment; precision in position measurement meant the electron's momentum became proportionally uncertain. The same was true for particle momentum and time and for angular momentum and spin angle as pairs of variables. Planck's famous Uncertainty Principle can be expressed as DpDx h/4ţ or DE Dt D h/4ţ (read, "the uncertainty in momentum times the uncertainty in position is greater than or equal to Planck's constant, h," etc.).
The phenomenon is not unlike the work of a pollster who sets out to measure public opinion. If he is hasty, works rapidly, but alerts the public so that they become opinionated, and if his sampling methods are not careful, he will get results quickly, but his results will not likely be very representative of the true state of public sentiment on the topic. A second pollster who takes a longer time to collect his data, works quietly, and takes care so as not to alert people ahead of time will get better results.
Recently, QM has been applied to cosmology in attempts to unravel the early history of our universe-assuming the basic Big Bang model is correct-and assuming the speed of light is a fixed constant in time!
All of the above discussion is based on the assumption-since Einstein-that the speed of light, c, is indeed a fixed constant. However as we noted in our earlier Personal UPDATE articles on the aether, the velocity of light, c, is determined by the properties of space - and space may be a very real medium after all. When all of the available measurements of c are carefully studied-using the best possible methods of statistical analysis-the result is that the speed of light has apparently decreased in the past 300 years-with a statistical confidence level of at least 95%.9"
