If You Follow The Straightest Possible Path Through A Spacetime Diagram

What is curved spacetime. Earth is following the straightest path possible through spacetime but this path happens to go around and around the sun.

Einstein S Second Revolution Movement On The Surface Of The Earth

Part a you know that you are following the straightest possible path through spacetime if answer.

If you follow the straightest possible path through a spacetime diagram. Circles that were evenly spaced in flat spacetime become more widely spaced near the central mass. Any time your worldline is perfectly straight cany time your worldline is following the straightest possible path through spacetime dany time you are very far from any planet eyou can never be truly weightless. Since i dont throw the ball i just drop it it starts in a path roughly like that of the blue arrow.

Spacetime can be curved just as a piece of paper can be curved. Correct prelecture reading question s310 part a which of the following correctly describes the relationship between newtons theory of gravity and general relativity. The only possible interpretation of the curving laser beam then is that the space inside the cabin is in some way curved.

Any time you are traveling through space at constant speed b. The ball wants to take the straightest possible path through spacetime. If we combine this concept with einstein s principle of equivalence then it would appear that light in the presence of gravity follows a curved trajectory or put in another way gravity bends the path of light.

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. Earth is following the straightest path possible through spacetime but this path happens to go around and around the sun. The issue is it is 2d and we have to ignore any effects of friction bc there is no friction in space.

In flat regions of spacetime freely moving objects move in straight lines. 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. What is spacetime.

We use it to represent spacetime. This is a path of constant radius where the only motion is forward in time. The three possible geometries for spacetime are flat spherical and saddle shaped.

Earth is following the straightest path possible through spacetime but this path happens to go around and around the sun. Spacetime is the four dimensional combination of space and time that forms the fabric of our universe. Suppose two lines appear to be parallel but eventually meet.
