God's Compensation/History/Overview of multi-dimensional theory
Multi-dimensional theory started as an area of theoretical mathematics, and later made its way into the status of a real scientific discipline within the realm of physics when Albert Einstein's theory of universal gravitation, witch posed that gravity is created by a warping of 3 dimensional space that causes it to contract in on itself around massive objects, was proven. While Einstein was not setting out to prove the existence of a 4th spatial dimension, the validation of his theory of gravity showed the scientific world that a 4th spatial dimension simply had to exist in order for space to fold the way it does around massive objects as Einstein demonstrated.
Pre-Einstein history
Before Albert Einstein made the ground-breaking discoveries that started the ball rolling toward our current understanding of multi-dimensional theory, there was already a lot of talk about the 4th dimension. What got the concept of the 4th dimension started in people's minds is something that is lost to history, but it most likely came out of the Pythagoreans, a cult in the 1500s that named themselves after the Pythagorean theorem and believed that mathematics was the answer to everything in the universe. It is easy to surmise that they might have gotten to talking about the 3 spatial dimensions of this world and got to obsessing over a theoretical 4th dimension and what it might mean.
Fast-forwarding to the 20th century, in the mid 1960s there were various new-age religions that picked up this old concept of a 4th dimension and took a liking to it. The understanding that these new-age religions had of real multi-dimensional theory was rather poor, and they confused it with parallel-universe theory. When a member of a new age religion talks about the 4th dimension, they usually do not understand it to be a physical geometrical angle that exists in theory, they think that the 4th dimension is a parallel 3 dimensional world where fantastic and wondrous things happen. It is stated by these new-agers that the 4th dimension is in physical contact with our 3rd dimension, and it is the realm in witch your soul dwells attached to your physical body by a thread.
While most of the talk about the soul and the realm of the mind were rejected by anyone who was not a member of some new-age religion, there were still several proper scientists at this time who mulled over the concept of a 4th dimension as it had entered into the popular lexicon as a subject of discussion. Rather than being a dimension of mind though, most scientists posed that time could be defined as the 4th dimension.
Albert Einstein's contribution to multi-dimensional theory
There are scarce few people today who can truly appreciate just how much Albert Einstein shook the world and how much he advanced the leading edge of scientific research. This is due mostly to the fact that the results of his research are not needed by the general person on the street to live their life, even though half the things they touch on a daily basis exist only because of his research.
Albert Einstein has 2 great scientific accomplishments to his name, and each of these accomplishments formed a foundation for a new scientific renosaunce that is responsible for just about every single piece of technology that was invented since then, and was also of vital importance in the space program. Accomplishments are as follows.
1. He proposed the Theory of Relativity, a theory based upon the speed of light stating that mass as well as some of the commonly accepted constants of the universe actually change according to the object's speed, and that these changes become more and more pronounced as it approaches the speed of light. He expressed this phenomenon in a mathematical equation that actually allows these changes to be calculated and reliably reproduced and observed in a lab, thus proving his theory to be true. That mathematical formula is E=MC squared, where E=Energy, M=Mass, and C= the speed of light.
2. He proposed a new theory of gravity. Before Einstein came along, Newtonian physics stated that gravity exists. When Einstein came along with his theory of universal gravitation, he became the first to actually theorize as to WHY gravity exists. He was the first to actually figure out what causes gravity to work. In his theory of universal gravitation, he posed that objects with mass actually warp 3 dimensional space around them in a manner similar to how a heavy object would warp the 2 dimensional plane of the surface of a trampoline. This theory was later proven correct in an astronomical observation expirament where a high-quality camera was used to photograph a lunar eclipse, and it was observed that the light from some stars witch should have been completely obscured by the sun were in fact visible. This proved that the light from the stars was actually warping around the sun to be visible on the other side due to the sun's extreme mass.
Einstein never truly set out to study multi-dimensional theory, however his study of gravity lead to our world's first existing proof that a 4th dimension existed due to the fact that a 4th dimension has to exist in order for 3 dimensional space to warp in the way Einstein showed us that it did.
