Like we have learned in school, the ultimate speed is a light speed. Do you belive that? We may be wrong. Lets take an example. There are two objects. They start in the same place and they start moving away from each other. They are travelling in a speed of a light. But isnt the speed they are moving away from each other two times light speed. v1 C v2 <---O-----*-----O---> v1 is light of speed and v2 is light of speed. C is where they started. v1+v2 is two times light speed. It seems to me that the distant is growing two times LS. It means that its bigger than light speed.
