To solve the problem of constant speed of light we have to look at the
RELATIVITY of SIMULTANEITY A world at a specific moment in time is made of simultaneous events. We believe that the world in which we live is one and the same for everybody. You tacitely think that when events are simultaneous for you, then they are simultaneous for everybody. Einstein proves that's wrong! People moving relative to you will NOT agree with your simultaneous events. They will not accept they are living in the same world of simultaneous events as you do. The constant speed of light and the relativity of simultaneity forces us to read our Spacetime map in a completely different way. I'll explain and show you how it works. Let's refine our Spacetime map and introduce a train. The sketch on this page shows a train with a little cabin at the front. Mr Jerry is in the cabin. At the back of the train Mr Tom stands looking at two flagposts on the train: a square flag and a triangle flag. A car approches the rear of the train, and drives past the train. You sit in the car. We will concentrate at the car and the train. The train's speed in the landscape, and the car's speed in the landscape are of no importance. Only the relative speed between the train and the car is important. Furthermore: for Tom the car approaches him, but for you the train approaches you. An observer measures the environment relative to himself, his measuring system. |
