Change the way gravity works in the game

From my other post :
http://universesandbox.com/forum/index.php/topic,30.0.htmlI was playing with the sandbox, which is great

but I was playing with the solar system and deleted the sun. It appeared all the planets were effected simultaneously and wanted to know if the sandbox would change to use the method where gravity effects the planets at the speed of light. For example, if the sun was deleted, it is expected to effect the Earth after 8 minutes. Just wanted to inquire

great stuff.
