In 1905, Albert Einstein created the Special Theory of Relativity. In this theory, Albert Einstein stated that no one single place in the universe is suitable as an absolute point of reference because everything is moving. In other words, nothing in the universe is always at rest in respect to any other object. Any object can be used as a frame of reference, but because everything is in motion, it is correct to say that the car moves past a house, or that the house moves past the car. All objects are in motion because of the earth’s rotation on its axis around the sun. Albert Einstein also stated in his Special Theory of Relativity that the rate of motion between any ray of light and any observer is always 300,000 km/s, or 3.0 x 10^5 km/s. Ten years later, Albert Einstein created the Theory of General Relativity. In this theory, Einstein stated that objects accelerate in respect to each other. The Theory of General Relativity also states that acceleration and gravity cannot be distinguished from each other. In this theory, Albert Einstein also stated that smaller objects tend to move tward larger objects because the larger objects warp the space around them GRAPHICS COURTESY OF GRAVITY PROBE B IMAGE ARCHIVES
