A speci c point on a space time diagram is called an \event. Spacetime diagram what the rocket ship really sees is not odd. In this class we will explore how spacetime diagrams may. Spacetime diagrams, spacetime, geometry introducing spacetime classically we have an absolute time, which can be viewed as a onedimensional euclidean space, r, plus an absolute threedimensional space, r3. We had the situation where im drifting through space. A point on the spacetime diagram is called an event. Weve been through the first few episodes of our crash course on general relativity, and came out alive. Consider a flight to a star 3 lyr away at a speed of vrel 0.
Introduction to special relativity and minkowski spacetime. The vertical value of this event is the time as measured by observer 1. This is a point in space at a speci c moment in time. Keck science center, the claremont colleges a space time diagram shows the history of objects moving through space usually in just one dimension. Time and space are two separate spaces and the movement in one space. Introduction to special relativity and minkowski spacetime diagrams. In the jargon of spacetime diagrams, the green point on toms and sarahs plots is an event and the red or blue trajectories are worldlines. Take a line from the event, parallel to the space axis of observer 2.
