Center of Krunskl Szekeres coordinate

In summary, the question is asking about the flatness of spacetime at the center of the Kruskal-Szekeres coordinates. It is clarified that a coordinate system without a metric does not provide information about spacetime curvature, and the asker is asked to specify if they are referring to the Schwarzschild metric for an eternal black hole or a spherically symmetric mass. The asker's source for the statement about spacetime being flat at the center is also requested.

does the question make sense?
 
  • #3
so, no idea?

A coordinate system without a metric doesn't tell you anything about spacetime curvature, do you mean the Schwarzschild metric expressed in Kruskal-Szekeres coordinates? And if so, do you mean the Schwarzschild metric for an eternal black hole, or just for a spherically symmetric mass like a planet? Not that I would know the answer either way myself, but if what you're asking is clarified then maybe someone else would. Where did you read/hear that spacetime was flat at the center, by the way?
 

Related to Center of Krunskl Szekeres coordinate

What is the Center of Krunskl Szekeres coordinate?

The Center of Krunskl Szekeres coordinate is a point in space that is used as the reference point for the Krunskl Szekeres coordinate system. It is also known as the origin point and is used to measure the distance and direction of objects in the coordinate system.

How is the Center of Krunskl Szekeres coordinate determined?

The Center of Krunskl Szekeres coordinate is determined by the creators of the coordinate system based on the specific needs and purposes of the system. It may be chosen based on a significant astronomical object or a specific location in space.

Can the Center of Krunskl Szekeres coordinate change?

Yes, the Center of Krunskl Szekeres coordinate can change depending on the needs of the coordinate system. For example, if a new object is discovered and becomes the main point of interest in the system, the origin point may be shifted to that object.

How does the Center of Krunskl Szekeres coordinate affect measurements?

The Center of Krunskl Szekeres coordinate is crucial in accurately measuring distances and directions in the coordinate system. It serves as the starting point for all measurements and any changes to it can significantly affect the accuracy of the measurements.

Is the Center of Krunskl Szekeres coordinate the same for all coordinate systems?

No, the Center of Krunskl Szekeres coordinate is unique to each coordinate system. Different systems may have different origin points depending on their specific purposes and needs.
