Special and General Relativity

                                                                  ***
 Albert Einstein's theory of “Special Relativity” which he published in 1905, determined that the laws of physics are the same for all non-accelerating observers, and the speed of light, when in a vacuum, was independent of the motion of the observers.
   This established a new set of rules for the law of physics. This established a new era for the concept of time and space. Albert Einstein published his theory of “General Relativity” ten years later in 1915.
   In this theory he determined that massive objects cause distortion in space time, this we feel as gravity.  When two objects exert a force of attraction on one another it's known as gravity. Evan at the center of earth, this force is pulling you toward it. This is what keeps you on the ground. Your center of mass is pulling back at the earth, with much less force.
    Sir Issac Newton quantifies the gravity between two objects when he formulated his three laws of motion. However newton's law assumes that gravity is an innate force of an object that can act over a distance.
   As a result of Albert Einstein's research into special relativity it was determined that time and space were interwoven into a single concept, known as space -time.  Events that occurred at the same time for one object, could occur at different times for another object.
   As he worked out his formulas for General Relativity, Einstein realized that  massive objects caused a distortion  on time -space. Imagine setting a large object in the center of a trampoline, the object would press down into the fabric, causing it to dimple. If you were to roll a marble around the outside of the trampoline, it would spiral in towards the object.
   The marble would be pulled toward the object in the same way that the gravity of the earth pulls at rocks in space. Although we don't have instruments that can measure space-time, several theories associated with the warping have been confirmed.
   Light around a massive object, such as a black hole, is bent causing it to act as a lens, for what ever lays behind it. This is a method used by astronomers to study stars, and galaxies behind massive objects such as planets. This is called gravitational lensing.
  An Radio-Telescope, which wasn't put into use until the 1960's. They were able to detect radio waves coming off the sun, the milky- way and a few closer stars.
    In doing this they were able to detect some other unexplainable objects. They were very small but extremely bright. They were given the name Quasi-Stellar objects. Or Quasar's.

 Intense discussions were taking place among astronomers, some of these Quasars were moving at 1/3 the speed of light. Stepping outside of the box, and taking a look from a different perspective.
   There were some astronomers who felt that they were created from the distortion of gravity from a black hole. Or could it perhaps be the opposite end of a worm hole which is called a white hole.
   If this is actually a white hole it would have to be extremely far away. Several billion light years away. It would produce as much energy as a entire galaxy.
   Another thought which is possibly more reasonable. Perhaps the Quasar isn't this bright after all, could our understanding of the size of the universe be a factor, could the universe be expanding?
   Could we be dealing with a civilization that was able to absorb the energy of other stars and galaxy's which would be why it is so bright ? If this is actually what is happening, it is a thought that has been out there for a while, it is called the Active Galaxy Theory.
   Since the 1980's astronomers internationally have been accepting the active galaxy theory as anacceptable explanation for Quasars. There are also concepts of “Blazers and Radio Galaxy’s” are thought possibly Quasars viewed from a different perspective.
   It is now apparent that Einstein's theory of Special and General Relativity is no longer a theory but hard fact. With a understanding of the concept of Time-Space it helps in the understanding of space travel and how space vehicles from millions of light years away could possibly travel to our planet.
