If an object is moving constantly, then the gravitation for this object will be changed comparing to the rest. If two objects are moving constantly in different location, they will cause a mutual affected force. This force will point to each other. All these four effects are detectable. Even my first article has clearly shown us that.
Truths are always truths.
You are very welcome to examine any point above or below, and any point in my article by using any means including mathematics, physics, astronomy and whatever, as well as their corresponding experiments, if applicable. Today's physics assumes that the forces which a particle receives from the fixed electrical field sources are constant during its moving. It will vary with the moving speed v of this particle. From point 1, if a particle's velocity approaches to the speed of light c, this particle then will receive NO force. If we use other force sources, for example imaging if this particle like a jet, then we can broken the speed of light c easily.
