Change the space gauge!

Going out on a limb:

Quite a few space gauges need updating to keep up with incoming data results.

One of the big ones for general relativity is measuring the expansion of the universe. Modern science seems to stick to hoping to gauge that by the energy density or budget, like rho or lambda, and we are to derive accurate readings for the universe's expansion through those. They have not yielded accurate or high resolution to date despite being utilized by almost every scientist over decades. It has become more of a guessing game, like pin the tail on the donkey or knock open the pinata.

Another technique was developed back in the 1920's by de Sitter and Friedmann. They did not totally rely on the energy budget. In fact, de Sitter's 1917 original work up allowed no mass, just volume.

They included geometric measurements to increase accuracy, like the Ricci tensor and scalar. Designated r(t) The calculations are better suited to measure through volume, not just mass. (Mass, which is found to have a diminishing role for influencing the universe, especially in the far future). This could have a significant role in determining in what way the universe could be an open one.

An effective work  in this line is presented by Tommi Tenkanan in arxiv. 1901.01794.

This utilizes the R, Ricci scale although it continues in accordance with Einstein approach even though it shows the possibility of curvature divergence in the paper.
