On Oct. 30 2007 we posted an article from our blog "The Imagineers Chronicle's" called "Embedded Dimensions" viewtopic.php?f=2&t=1146&p=13082&hilit=shadows&sid=a7837d85342459c2f7363277e6525c4a#p13082 to this tetraspace forum which briefly described how and why we feel defining a universe in terms of four *spatial* dimensions is more consistent with observations than one consisting of four dimensional space-time.
At that time we received several comments which helped us to develop our theoretical model and redirected portions of our research of four *spatial* dimensions to new areas.
We have posted our some of this research to "The Imagineers Chronicle's" http://www.theimagineershome.com/blog/ and have devoted considerable time to editing and adding some of your ideas to our Shadows paper http://www.theimagineershome.com/shadows.html .
We would appreciate it if you can find the time revisit us and comment on the progress or lack there of in our theoretical model.
Thank you for your time and help
