Newtonian Gravity is practically that all matter pulls other matter with gravitational force. The Larger Screen thing makes scale:2. This isn't good if you don't have over 1024x768. Fullscreen is even somewhat good. You can revert to normal by running command-line options like that: 1) Open CMD(run -> cmd) 2) Drag the Powder Toy EXE into the command prompt. This makes the path appear. 3) To the end add scale:1 <-- This is a commandline option. Also usable via shortcuts.<br />
