Matter without the property of gravity

Is there matter that has all the properties of ordinary matter except for gravitational mass?

Probably not.

But wouldn't it be nice?

It would make conventional space travel easier if you could build space stations that aren't subject to gravity.

In my opinion, that makes the search worthwhile. The worst thing that can happen is that we find nothing.

So, let us search.

Project file

The file setup.pdf contains the theoretical considerations and the practical implementation of this project.

Data file

The set of data is available for every month beginning with September 2025 and will be actualized every new month ending with August 2026.

Every set of data is made from two Excel files.

One file contains the raw data with spurious mismeasurements.

In the other file, all sporadic measurement errors were replaced by the mean value of two adjacent measurements.

The zip-files will be updated at the beginning of each next month.

Up to now we have data only in the folder 09 2025.

Here you find the data files.
