Post about Einstein's view of space-time and the universe vs. "Classical" or Newton physics view of the universe. Cite sources, put your name at the beginning of art.

Newton's Theory: Isaac Newton revolutionized physics with his proposition that all bodies are governed by the three laws of motion. (The first law of motion states that a body continues in a state of rest or continues to be moving uniformly in a straight line unless a force is applied to the object. The second law states that the force applied to an object is proportional to its mass multiplied by acceleration (F=ma). The third law states that for every action there is an equal opposite reaction). Which we have already learned in class before and with these three simple laws, Newton created a whole new model of the universe.

Einstein's Theory: Einstein wondered what it would be like to travel along with a ray of light. Einstein concluded that the laws of physics //and the speed of light// must be the same for all uniformly moving observers, regardless of their state of relative motion. For this to be true, space and time can no longer be independent. Rather, they are "converted" into each other in such a way as to keep the speed of light constant for all observers. Space and time are //rel//ativ//e//, meaning they depend on the motion of the observer who measures them, and light is more fundamental than either. This is the basis of Einstein's theory of special relativity ("special" refers to the restriction to uniform motion).
