A Marble and a Photon: Single Speed Hypothesis

This study explores the concept of velocity within the framework of the physical interpretation of acceleration and deceleration for moving objects in space. A thought experiment involving a marble and a photon is employed to introduce the hypothesis that all objects in space inherently travel at the speed of light when in motion. Through a series of systematically structured thought experiments, this hypothesis and related conclusions are examined and substantiated. Newton’s first law of motion serves as the foundation for these scenarios, allowing for logical conclusions to be derived. The methodology prioritizes logical reasoning over detailed mathematical formulations to provide a more accessible presentation.
