GRAVITATIONAL PROPULSION RESEARCH GROUPS
There have been a number of Research groups associated with Gravitational Propulsion. The earliest was in early 80's and was a loose association of individuals offline that tinkered and researched some preliminary concepts.
On January 12 of 2004 a Yahoo Group was formed dedicated to Gravitational Propulsion Research. An odd fact about that group was the date of creation was constantly changing back and forth from Jan 12 to Jan 13.

These online Gravitational Propulsion Research Groups were discontinued in May of 2006 after the announcement of the electronic eavesdropping rules created by the government. While research continues in private, the online groups were dismantled to protect the privacy of the research. This site was instituted to record and maintain early non-confidential Data that is evidence of prior work in the art.
On July 14 2006, the Gravitational Propulsion Yahoo Group was created as a Yahoo Group to inform and discuss public knowledge of Gravitational Propulsion.This new information and discussion group can be seen by going to the same URL as the older group at;
