Einstein’s General Theory of Relativity holds much information pertaining to how the world works. Einstein starts his explanation of the General Theory of Relativity by explaining Newton’s laws of motion. He then compares one object’s motion to another’s that is on a different frame of reference. For example, one person is running down a road toward a tree while the other is driving away from said tree. He then applies this to objects which are in a “free fall” state, meaning that the main force acting upon them is gravity. Einstein provides further explanation of this simple law of physics with; “We shall assume the ‘truth’ of the geometrical propositions, then at a later stage we shall see that this ‘truth’ is limited and we shall consider the extent of its limitation,”(Relativity: The Special and General Theory, pg.7) This can be interpreted as Einstein seeking to add to these general laws of physics with his theories of general and special relativity.
When introducing his General Theory of Relativity, Einstein gives his definition of mechanics: “The purpose of mechanics is to describe how bodies change their position in space with time.”(pg.12) He goes on to explain that classical mechanics is not able to supply a “sufficiently broad basis for the theoretical presentation of all physical phenomena,”(pg.16) but he also states that he needs to give it a decent amount of credit since it “supplies us with the actual motions of the heavenly bodies.”(pg.16)
Einstein’s research then provides us with a revolutionary equation. This equation is E=mc^2. This means that the energy of a body equals the mass of said object times the speed of light squared. This equation has been proven time and time again, and it has yet to be disproved. Einstein also states that the speed of light is the fastest thing in existence. And many scientists have spent their entire lives trying to disprove this but have been unsuccessful.
Einstein also says that “space is a three-dimensional continuum,” which can be interpreted as space having not only one dimension but actually containing three dimensions.(pg.51) What are the other dimensions like? Are they necessary for the survival of this dimension? Space and time are very complex, and more information is being learned about them all the time. People may never be able to uncover the mysteries of space and time, but we can learn. And as long as we can learn, we can advance.
