Superluminal Experiment (Part 2)

Everything in the universe was relative. An object at rest in a vacuum, unaffected by any external force, would begin moving upon receiving energy from outside. If it remained undisturbed by external forces during that time, it would continue moving forever in a straight line at a constant speed.

This was also an interpretation of Newton's First Law: an isolated particle remained at rest or moved in a straight line at a constant speed.

The particle's original state of rest had been altered by an external force, so it would move in a straight line at a constant speed. From this, it could be understood that motion itself was merely a state. Maintaining that physical state required no energy; only changing one's state of velocity required energy.

But why was that?

The Collectors now had their own answer: motion was both a physical property of matter and an attribute of spacetime.

Motion was relative. Two objects moving in the same direction at the same speed were relatively stationary.

This meant that determining whether an object was moving depended primarily on the reference frame selected. If a reference frame moving in the same direction at the same speed was chosen, the moving object would be stationary. Conversely, if a reference frame not moving in the same direction at the same speed was chosen, the object would be moving.

Wasn't that strange? Determining whether an object was moving actually depended on another object's own state of motion.

Could it be reversed, then? Suppose every possible reference frame in the entire universe was removed, leaving behind only a single particle. Then an invisible hand of God gave that particle a thrust approaching infinity. What would happen?

Would this object be moving? Or would it be stationary?

By normal logic, that particle would certainly
