If you follow the straightest possible path through a spacetime diagram,. PDF ASTR 1020 Class Review 11/12/2021 and mass are equivalent) produces a curvature in spacetime. Curved spacetime tells matter to move in the straightest path possible. The twist is that in a curved spacetime, a "straight" path may not look like a straight line. We will try to get a handle on what the curvature of spacetime means next class.

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. Astronomy S3 (spacetime and gravity) Flashcards - Quizlet They are following the straightest possible paths through spacetime, and those paths curve so that the probes 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.

Spacetime Geometry Inside a Black Hole - Jim Haldenwang Instead, we define these geodesics as the straightest possible paths through curved spacetime.

Time runs slower in places where gravity is stronger. Questions for Chapter S3 - Questions for ... - Course Hero The mass of the Sun causes spacetime to curve , so freely moving objects ( such as planets and comets ) follow the straightest possible paths allowed by the curvature of spacetime . Circles that were evenly spaced in flat spacetime become more widely spaced near the central mass . Chapter S3 Flashcards - Quizlet Time runs slower in places where gravity is stronger. Earth is following the straightest path possible through spacetime, but this path happens to go around and around the Sun. we use it to represent spacetime. The issue is it is 2D and we have to ignore any effects of friction bc there is no friction in space. Gravity and warped time—clarifying conceptual confusions ... 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 ].
