Why Relativity Says You Can’t Travel Backward in Time

AcePhysics.org https://acephysics.org ________________________________________ Why Relativity Says You Can’t Travel Backward in Time In this video I explain how special relativity determines the causal order of events in spacetime using light cones and the spacetime interval. We discuss the difference between timelike and spacelike events, and why observers can sometimes disagree about the order of spacelike events. However, relativity also shows that no signal can travel faster than light, which means causes must always occur before effects and true backward time travel is not possible. ________________________________________ Related Video Simultaneity – Relativity’s Most Important Lesson    • Simultaneity Relativity’s Most Important L...   ________________________________________ Physics Tutoring with Dr. Jacob Hudis I am Dr. Jacob Hudis, and I offer professional physics tutoring through AcePhysics.org. I studied Applied Physics and Applied Mathematics at Columbia University, earned a Master’s degree in Physics from Johns Hopkins University, and completed my PhD in Physics at Florida State University. I have many years of experience teaching physics and helping students succeed in challenging courses such as AP Physics, Honors Physics, and calculus-based college physics. Through AcePhysics.org, I provide one-on-one tutoring for high school and college students, helping them understand difficult physics concepts and improve their grades and exam performance. ________________________________________ AP Physics Tutoring and Summer Preparation At AcePhysics.org, I work with students both during the school year and over the summer. Many students use summer sessions to prepare for upcoming physics classes, while others meet during the school year for homework help, test preparation, and deeper understanding of the material. I regularly help students with: • AP Physics 1 • AP Physics C Mechanics • AP Physics C Electricity and Magnetism • Honors Physics • College Introductory Physics Students who work with Dr. Jacob Hudis at AcePhysics.org often gain stronger problem-solving skills and a much deeper understanding of physics concepts.
