... lab is relevant to the person that is in the lab. The principle of relativity theorizes that experiments in an internal frame, is independent from uniform velocity of the frame. An example of this is the speed of light. The speed of light within the internal frame is the same for all, regardless of the speed of the observer. Two events that are simultaneos in one frame, may not be ... the simplist equations, he found a set of 10. To test the general theory Einstein performed three tests. Gravitational red shift, light deflection, and perihelion shift of mercury. To test light deflection, ...

... . He used spectral analysis to demonstrate this theory, analyzing the composition of reflected light in terms of its elemental makeup . Hodges notes that this analysis allowed Newton to envision: "light and visibility of objects as a result of the rather mechanical movement of a host of miniscule particles or "corpuscles" of light through air, from object to observer, at the speed of about 168,000 miles per second". In more than one way Newton ... 's theories of light interrelate with his theories of gravity. In turn, Newton's gravitation formula pertains from every aspect ... ...

... dated back more than two hundred years. According to Einstein's general theory of relativity, space and time together can be regarded as forming a four-dimensional space called space-time, curved by the matter and energy in it. Also according to the theory of relativity, nothing can travel faster than the speed of light but most compact objects imaginable are predicted by General Relativity to have ... such strong gravitational force that nothing can escape them- not even light. For this reason, it is called a black hole; light, as a result disappears from the visible universe. John Mit...
