Inertial and Accelerated Motion in Spacetime Physics

Probably the concept of motionConcept of motion—seemingly the least doubted of our perceptual experience—might have been among the observations of ancient thinkers that gave rise to the proverb “The darkest place is under the lantern.” “The darkest place is under the lantern” For centuries the greatest minds have been struggling to understand what people have always thought they were fully familiar with—motion. The Eleatics (fifth century BC)Eleatics held a completely counter-intuitive view on motion, which is amazingly similar to the spacetime view of the world. According to the Eleatic school of thoughtEleatic school of thought the analysis of the observed motion and change revealed internal contradictions in these phenomena which led the Eleatics to conclude that these were nothing more than mere illusions and that the true reality was an eternal existence [1, 2].
