When space probes, such as Rosetta and Cassini, fly over certain planets and moons, in order to gain momentum and travel long distances, their speed changes slightly for an unknown reason. A researcher has now analyzed whether or not a hypothetical gravitomagnetic field could have an influence. However, other factors such as solar radiation, tides, or even relativistic effects or dark matter could be behind this mystery. An artist’s rendition of Rosetta probe during a flyby.

An international team of physicists has shown that the mass ratio between protons and electrons is the same in weak and in very strong gravitational fields.
