We use basic, light speed 300000km/s to measure, space long distances.


A= Source. B= Moving, travelling thing, which A putout. C= Observer.


1. If B is constant. C can measure B:s constant. If C want to know what is distance C--A, B must have this distance information.

2. If B is constant, then A must also be constant.

3. How B can have distance information, because it dont know, where C is?

Measuring space distances at theory 'light speed-radiosignal speed-etc.)', it cause errors.

We can see this.
