I had to cuss my highschool physics teacher out when discussing relativity. There has to be a universal frame of referance. Speed cannot really be measured as distance per interval unless a frame of referance is universal.
Say an object is moving. That objects movement in itself never changes. An observer from one frame of referance might measure it to be moving at 10m/s. An observer from another frame of referance might measure it to be moving at 100m/s. But the observer's frame of reference is not relevant to the object's movement in itself. All objects have an intrinsic speed that is constant regardless of frame of reference of measuring distance per interval.
Why would the speed of light be different from the speed of anything else? If light travels at 300million m/s, then it does so regardless of frame of reference?
CONSIDER AN IDEAL SCENARIO IN AN IDEAL PLANE
If an object travels 300 m/s, then why would it abide by different rules from anything else? If there is a train that is 3 billion meters long. The object would travel from one end of the train to the other in 10 seconds. If that train was moving at 2billion m/s on a track. After 10 seconds, the train would have traveled 20 billion meters. Thus, the end of the train would be at 23 billion meters from origin. Thus. the object had just traveled 23 billion meters in 10 seconds.
