Now, I do not get any data after August 24, 2025. All time series are obviously not continued. Is this my fault? Does anybody know how to access data for Germany after August 24, 2025? Here is the command I used: airtemp = AirTemperatureData[ stationen, {DateObject[{2007, 10, 1}], DateObject[{2026, 5, 20}], "Day"}] where "stationen" is the list of 11 cities defined as Entities (note, this code worked for the last 5 years) any help is highly appreciated.

That's all there is to it. Here's how it compares to FLRW: ![enter image description here][2] Red is the analytical formula, blue is FLRW. Using the full covariance matrix of the Pantheon+ SH0ES project, the reduced $\chi^2$ of 1.68 for the analytical formula is significantly better than 2.49 for the numerical FLRW solution. This is an outrageous claim, so it should be easy to debunk. The full paper is here: [Acceleration Law Article][3] and the notebook is here: [Acceleration Law Notebook][4]. I'd appreciate your feedback, positive or negative.
