LIGHT

VELOCITY OF LIGHT AND DISTANE FROM THE STARS Consider two trains moving along parallel tracks, with only one train having head light. If both trains are running in opposite directions, the speed of the train with head light will appear as the sum of the speeds of both trains. If one train is stationary, we will get a different result. If both trains are running in the same direction, the net speed only will be observed. All heavenly bodies are moving. So we will never know the actual speed of light coming from the stars. The calculation of speed of light is impossible, as also the distance from the stars, which is calculated on the assumption that the speed of light is constant In the laboratory, observation is within a small stretch. It cannot be accurate, when we consider the infinite space. Einstein thought that the velocity of light is constant. Philosophically, nothing is constant .Every body suffers fatigue. So the speed of light too will be maximum, when it starts from the star, slowing down, as it moves great distances in space. Light is only a small part of the total radiation coming from all the stars, affecting the speed of light. So to say, space resists!
