16. Comoving Coordinates to Explain the Expansion of the Universe
With space expanding, quantities will also change over time. Some believe that because of this, comoving distances could be the cause of earth’s expanding data.
The metrics we have used, and still use today, can only define the distance between local points, which leaves plenty of room for error if the points are constantly moving.
Yes, these points can determine the space between points in a straight line, or even of a curve, but now theorists are beginning to blame this theory for the expanding numbers of space.
They now say that comoving coordinates shouldn’t be directly measured because of all the discrepancies they are causing.
