39 if you follow the straightest possible path through a spacetime diagram,

A space-time diagram shows the history of objects moving through space (usually in just one dimension). A speci c point on a space-time diagram is called an \event." To make a space-time diagram, take many snapshots of the objects over time and set them on top of each other. Lines in the diagram are like \contrails" through time. The red galaxy distorts the spacetime around it, very much like the "mountain" in figure 2 so that the straightest possible path light coming from the distant blue galaxy behind it is curved. The result is that light gets spread out and "lensed" to form the Einstein ring you see in the image.

According to Einstein, there is no force of gravity; objects in free fall follow the straightest possible path through curved spacetime (figure 2). Details of the model, an overview of its strengths and limitations, and student responses from three years of classroom trials can be found in the original publication [ 1 ].

If you follow the straightest possible path through a spacetime diagram,

object's path through spacetime in a spacetime diagram. • Vertical worldline: no motion ... is following the straightest possible path through spacetime. • If you feel weight, then you are not on the ... the twin following the shorter path through spacetime. a.) Following the shortest path between two points in curved spacetime b.) Traveling at a constant velocity far from any massive objects c.) Both of the above d.) None of the above Answer: c . 7.) According to Einstein, if an object does not follow the straightest possible path as it travels between 2 points in spacetime, it a.) "feels weighty" therefore, it will follow the straightest possible path through spacetime ; if spacetime is curved near a massive object, so will the trajectory of light; 31 Gravitational Lensing. During a Solar eclipse in 1919, two stars near the Sun ; were observed to have a smaller angular separation than ; is usually measured for them at night at other ...

If you follow the straightest possible path through a spacetime diagram,. If you follow the straightest possible path through a spacetime diagram. A freefalling object then follows the straightest possible path in spacetime. Gravity arises from curvature of spacetime. Now a straight line takes me from the roof to the ground. Around a black hole spacetime becomes so curved that nothing can escape. Consider a spacetime diagram that show worldliness for three objects: ... How can you tell whether you are following the straightest possible path through spacetime? If you are floating freely, then your worldline is following the straightest possible path through spacetime. If you feel weight, then you are not on the straightest possible path. If you follow the straightest possible path through a spacetime diagram • You must be traveling at the speed of light • You get from one place to another as fast as possible • You are in "free fall" - you do not feel any weight or acceleration • None of the above If you follow the straightest possible path through a spacetime diagram D. Earth is following the straightest path possible through spacetime, but this path happens to go around and around the Sun. 6. According to general relativity, how is time affected by gravity? A. Time is not affected by gravity. B. Time is stopped in places where gravity is strong. C. Time runs slower in places where gravity is stronger.

Hello, I've been doing some relativity self-study and have what may be a silly question but one that has me scratching my head. I understand conceptually that under GR, gravity is not a force but rather the effect of objects following the straightest possible path (a geodesic) over curved space-time. B) Earth is following the straightest path possible through spacetime, but this path happens to go around and around the Sun. C) Earth orbits the Sun because Earth and Sun are connected by a "rope-like" set of invisible, subatomic particles. D) Earth orbits the Sun because a spacetime diagram shows the Sun to be a bowl-shaped dip in a rubber sheet. Students learn that a straight path through spacetime does not necessarily look like a 'straight line' in a given representation. Students learn to shift their perspective to understand that objects in free fall follow the straightest possible path through spacetime. The following animation shows the elevator falling towards the earth, following our planet's gravitational pull: ... As long as no external force is acting on an object, it will move on a straight line through spacetime: at a constant velocity along a straight path. ... If you want to move on a spherical surface in the straightest possible ...

They are following the straightest possible paths through space time, but those paths happen to meet. Suppose the room in which you are sitting was magically transported off the Earth, and sent accelerating through the universe at 9.8 m/s2. • Thus their orbits are the straightest possible path in spacetime. • Since this straightest possible path in spacetime is not a straight line, spacetime is curved. • The shapes & speeds of the orbits can thus reveal the geometry of spacetime • Gravity thus appears due to the curvature of spacetime by massive objects. If you are floating freely, then your worldline is following the straightest possible path through spacetime. If you feel weight, then you are not on the straightest possible path. Why don't we know what gravity is? The ball wants to take the straightest possible path through spacetime. Since I don't throw the ball, I just drop it, it starts in a path roughly like that of the blue arrow. This is a path of constant radius where the only motion is forward in time.

Exercise 1.4. 1. For each of the events in Figure 1.4.2, indicate whether the other events are in the past, future, or elsewhere regions. Figure 1.4. 2: A spacetime diagram with four events indicated. Answer. For each event, you can draw a pair of lines at 45 degree angles to divide up the space.
