Another Negative Positive Result

A report on the arXiv describes an experiment that searched for “chameleon fields,” a modified gravity theory that seeks to explain dark energy without a cosmological constant. The negative result rules out these fields in a large part of the parameter space, but not all of it.

In our model, dark energy is a true cosmological constant, as I explained here, so for us this result is positive and expected.

News of Interest

In terms of new ideas, things have been pretty dull in the physics community lately. However, there have been a few negative experimental results that are bad news for some old ideas and favorable news for the model I’m describing in this blog.
