RELATIVITY: The Special and General Theory The theory of relativity was introduced by Albert Einstein around the early nineteen hundereds. It is a theory which enables the human mind to understand the possible actions of the universe. The theory is divided into two parts, the special, and the general. In each part, there is a certain limit to which it explains and helps to comprehend. In the special, Einstein explains ways of understanding the atom and other small objects, while the general is designed for the study of large objects, such as planets. The theory of relativity having being created, succeeded the two hundred year old mechanics of Isaac Newton, thus showing Einstein as more of a futuristic thinker and adapter. Einstein introduced the concept of Relativity, which means that there is no absolute motion in the universe. Einstein showed that humans are not in a flat, absolute time of everyday experience, but in a curved space-time. Take for example the Earth as a whole. The earth has a circumference of around twenty five thousand miles, and it can be covered within a twenty-four hour time frame. Having this completion of distance covered within the set amount of time, shows that the Earth rotates a little over one-thousand miles per hour. it can be assumed that something in the solar system is not moving, and we can measure how fast the earth is moving by relative to the object. However, no matter what object is chosen, it is moving as well, thus showing that nothing is fixed and that everything is moving, and it is unknown how fast or in what direction. The Theory of Relativity is a theory compressing mechanics, gravitation, and space-time. Having known this, it is seen so that all things are related, but can not be thought of as individual. The Theory of Relativity is known for having two parts to it. The first part is the special relativity; the other is the general relativity.
