Space and time will change to keep the speed of light constant. Both space and time will change because they are relative to each other. An example of this is there is one person going at a steady 10 mph. If the person was going south and decided to go southeast, the person would slow down a little bit. The person is going south at a steady speed of 10 mph, but a little amount of this speed needs to be diverted into the eastward direction causing the person to slow down a little. This is how time changes to make sure it is relative to space. This idea is special because this is in a special instance where there is no gravity to curve space. Einstein created the general theory of relativity to talk about if gravity were in effect
