It is situations like this when we all have to just smile and enjoy the greatest trilogy ever to hit the silver screen. In the world of physics we can relate this to what is known as "The Grandfather effect" and Hollywood doesn't like to shell out the research bucks to correct these innaccuracies. Please note: I am very interested in physics but not so great at spelling:-) Anyway, you are right to assume that Doc and Marty of 1885 could have used there current knowledge to warn the 1955 counterparts but it would not have helped them. In the first scenario they would have just had to wait around to see if a gas can would reappear by their shear will as a result of future warnings. This would be no different than you or I sitting at our computers saying I want to turn my delorean into a time machine but instead I will let my future self do it and come back to this date to give it to me. Life must go on. In another scenario 1885 Doc and Marty would be successful and have a gas can ready and waiting as well as a spare part but if that happened in 1885 then they would not have the need for it in 1955 and it would again have been overlooked. Of course every situation could in theory just cause an alternative reality just as in the second movie. To clarify let me put it this way...If your grandmother slipped on a roller scate you left on the steps when you were 9 and broke her hip you would feel terrible and live many years with the guilt. You being a dedicated and loving grandson would spend your life building a time machine out of say a hot tub to travel back in time to make sure you put the roller scate away. The problem now is this...Having put away the scate your sweet grandmother never broke her hip and went on to win dancing with the stars and you as a result would have had a joyious guilt free life and never built a time machine. All these points are arguable and I myself could disagree with myself on every one of them but I just wanted to share a few ideas. I love the movies and even though all my memorabilia has been taken down and put into storage containers as well as my delorean being sold in order to make room for my second daughter I will always be a part of the mass group of people knowing how great these movies are. For now I think I will wait for my future self to build a time machine so I can make some money off the sports almanac, buy Universal studios and save the BTTF Ride. Take care of yourselves, enjoy the classics and don't forget your plutonium. I'll see you in the future!

To: dmcnews@xxxxxxxxxxxxxxx Date: Saturday, July 31, 2010, 8:32 PM Watching the movies for the millionth time today I had a thought.... In BTTF 3 I understand that in 1885 they could not use the Delorean that was already in the cave because that would make it impossible for Marty to get back to Doc from 1955...... But..... Gas was available in the future in 1955... They could have gone to the mine and taken some fuel from it to use in the 1885 Delorean before blowing it up with booze... Right??
