Editor's Notes
- Are Mass and Energy different entities? We said, in the twilight just before modern times, it was believed that only mass and energy mattered and that they were discrete factors which could never mix. Energy In the early 19th Century, Michael Farraday was a book binder’s apprentice but was interested in physics. Although he had no qualifications, he was able to get a job assisting Sir Humprey Davies after Davies suffered an eye injury in a lab experiment. Farraday’s great contribution to British science is the proposal that electricity moves in waves-- not merely through wires but from them in radiant waves. Current passes through a wire. If a compass is positioned near the wire, the magnetic force is neutralized by the electric force "inside" the wire. Mass or Matter It wasn’t proposed until the French Revolution that Matter might change form but could not be removed from existence (matter can neither be created nor destroyed). This radical proposition was proven by Lavoissie a scientist, tax collector, and victim of the French Revolution. He saved and carefully measured the oxidized iron rusted away from a pipe proving although the mass seemed to disappear that the rust was equivalent to the once-solid pipe.

- In 1887, Michelson and Morley became convinced, as many were, that light would travel faster in the same direction as the earth’s rotation than when traveling against the rotation. They built a very elaborate device to test their theory. They disproved their theory instead. Their experiments suggested that light moves at the same speed irrespective of direction. The conclusion that light cannot accelerate or decelerate became the basis Einstein’s Theory of Special Relativity ( Thorpe 48). Now if only THAT were true (Thorpe, Scott. How to Think Like Einstein. New York:Barnes & Noible, 2000). Our world of sequential places and times exists in a universe. Einstein’s calculations indicate that this universe of time and space is curved. Think of it as being shaped like the Snake River. You could travel one hundred miles on the river and be very near to the point where you started. That is very convenient for water rafting trips. You can raft for hours and arrive back where you started. This is like the element of Einstein’s Theory of Special Relativity called dilation: "Relative to a stationary observer on the ground, time aboard a spacecraft appears to slow down relative to the spacecraft: relative to the spacecraft, time for the observer on the ground seems to speed up. " (40). Calculations support the breakdown on the laws of physics at points in the wormhole. Quantum mechanics (or rules at the subatomic level) appear to take over here. While the Snake River is only recursive through space, Einstein’s math shows a universe that is also recursive in time. This means that two distant times and places are physically close." If, then, there is a way to avoid the extreme gravity to travel through the "wormhole," time travel would be entirely possible-- risky but possible.
- Mass or Matter It may seem self-evident to us today, but it wasn’t proposed until about the time of the French Revolution that matter can neither be created nor destroyed. This was a the radical proposition at the time it is proven by Lavoissie using oxidized metal. By the 1780s, people believed that motion together with friction was a source of the vis viva. One example said that motion generated heat. By the 19th Century, the vis viva came to be called energy. In 1807, Thomas Young resumed the experiments demonstrating that though the form of matter may change, the mass remains the same. The mass of an ice cube for example is the same as the water it forms from. The same is true of water turned to steam or wood burned to ashes. … and so the scientifically modern world accepts that matter can neither be created nor destroyed.
- Our universe of sequential places and times exists in a universe. Einstein’s calculations indicate that this universe of time and space is curved. My friend, Steve E. was a poor student with a thirst for white water. He would follow guided tours over cat 3, 4 and even cat 5 rapids. Then he would hitch-hike back to the lot where he parked his car. One of his bouts of insanity brought him to the Snake River. Here he found a river as twisted as he was. He could travel one hundred miles on the river and be very near to the point where you started. Ending a journey at the same point where you began is like the element of Einstein’s Theory of Special Relativity called dilation. Einstein’s calculations indicated that space was curved (like the Snake River). This means you could travel a very long distance in one direction and be close to your starting point. Therefore if distant places can also be close by, time must make an accommodation, Thus… "Relative to a stationary observer on the ground, time aboard a spacecraft appears to slow down relative to the spacecraft: relative to the spacecraft, time for the observer on the ground seems to speed up. " (40)
- About the time that Einstein was developing his four theories, others were considering Quantum Theory. This way of looking at the world considers two opposite truths for every condition. Consider electricity from a simple AC (Alternating Current) outlet. In AC mode, current moves sometimes forward, sometimes backward through the wire. At any instant it might be moving in either direction. You cannot know the answer for certain by external observation. If you are asked: “Is the current moving forward?” You might answer correctly by saying either: “True” or ” False.” But the mathematics of two correct answers raise some questions that old “facts” don’t explain. Calculations, for example, show a breakdown of the laws of physics at points surrounding the wormholes that might connect distant parts of space and time. Instead of the old laws of Newton and Einstein, quantum mechanics or rules at the subatomic level appear to take over. While the Snake River is only recursive through space, Einstein’s math shows a universe that is also recursive in time too. This means that two distant times and places are physically close." If then, there is a way to avoid the extreme gravity to travel through the "wormhole," time travel would be entirely possible-- risky but possible. It all depends on rules that apply to tiny new universes that are always in motion.
