In 1905, Albert Einstein changed the prevailing worldview of Newtonian physics for good with the introduction of his special relativity theory, followed in 1915 by general relativity. He proved Newtonian laws of physics are by no means static, but relative to the observer and the observed. Depending on the difference in speed between the observer and the object under observation, space begins to either shrink or expand and time slows down or speeds up. In Newton's universe, there are notions of absolute space and time. Space was seen as a three-dimensional stage, and time the ticking of a well-made clock. The two were separate and distinct. Dr. Einstein's special relativity, space and time, form one 4-dimensional space-time continuum with the speed of light being the only fundamental absolute measurement. Measuring distance in time may seem strange but consider the following examples. In the time of pioneers, distance was measured in time … for example getting from one city to another might have been agreed upon as a four days journey. Cosmotologists use light-years to measure distance. For example, our nearest star (besides the sun) is Alpha Centauri, which is about 4 light years from earth. 4 light years is the distance light travels in 4 years. Our sun is 9 light minutes away. When you see the sun, you are actually viewing it 9 minutes in the past. One of the illusions of space-time is that to see anything "out there" in space you are always seeing it backward in time. But because light travels so fast, it is almost instantaneous for distances on earth, so this illusion is not apparent. To give you a sense at how fast light travels, light can take 7.5 laps around the earth in ONE SECOND! Also, energy and matter were two distinct notions in Newton's mechanics, and there were separate conservation laws for both: the conservation of matter and the conservation of energy. Einstein, with his famous equation E=mc2 forever changed this notion as well. Matter and energy are interchangeable with energy being the more fundamental unit. This is one of the most important new scientific notions that we can apply to new understandings of the human body; namely, that we primarily energetic beings and secondarily physical ones! Even though quantum theory delivered a decisive coup de grace to Newton's physics, this outdated Newtonian worldview still persists stubbornly in medicine, biology, chemistry, geology and many other areas of science.
