After searching for “gravitational charges” in the Internet, I found the website quanten.de that has a forum (in german) where this topic is discussed. After a few days I was blocked to continue posting and for a week. Today (22.07.) I could post again, but after my first post I was completely banned. At least my former posts were not earsed from the system.
Edit (23.07.): The were earsed today.
The argumentation which I had with one moderator can be seen here: DOWNLOAD
