Classical general relativity (GRT) – well proven and also incomplete

Klassische Allgemeine Relativitätstheorie – gut bestätigt, aber unvollständig


This website has two aims:

1.) Provide evidence of incompleteness of classical GRT. Two pages suffice. See GRT - well proven and also incomplete?“ or in German „Ist die Klassische Allgemeine Relativitätstheorie unvollständig?“. Later, refined versions you will find in: Talks_Brandes_since_2014

2.) Provide evidence that these considerations become slandered. See Einwand-Diffamierung-2012 as well as Further_Counterarguments_since_2013.

Since 2016 there are two additional aims:

3.) Presentation of a review by Dr. habil. Ludwig Neidhart being helpful for your decision of whether my website has enough scientific background:



4.) More about our book and additional ideas.

Since the first publication of our book several additional ideas different from 1.) arose. They also became part of Talks_Brandes_since_2014. The latest one you find in:


Talk-DPG-2024-Abstract.pdf: The observational proof of Sgr A* being not a black hole


Some additional information: This website prefers Lorentz interpretation of SRT and GRT. Certainly, there is no difference with the experimental results of classical GRT including gravitational waves but the great exception: Lorentz interpretation of GRT predicts that there are no black holes in the galactic centers. Excitingly, this is going to be tested by the Event-Horizon-Telescope collaboration with first results since April 2019. The main result – image of Sgr A* – was released at 12.5.2022 and becomes discussed: see 4.) above.
The Nobel Prize in Physics 2020 to Reinhard Genzel and Andrea Ghez "for the discovery of a supermassive compact object at the centre of our galaxy" is fully satisfied by LI of GRT - as it should.
