I worte this on ATS, but would like to discuss it here. This deals with parallel universes and the possibilites. we will be touching ont his during the Time Travel research. I would like to know your ideas on this and the experiment that is added in there. For you Science Fair buff, then this will be a fun experiment as well. Dimensions... That is part of Time Travel possibly. You have to look at the arrow of time. Time the work and seconds were created by us, but the principal of time is there. Example: You can break and egg, but can you unbreak an egg? Is is possible to unbreak an egg? Well, the answer is yes. If everything was reversed, then you could unbreak the egg, but entropy says that it is basically impossible. So, off of this assumption, there is time and it is moving in a direction. One of the theories on different dimensions and time is that we are stuck in this fraction of a fraction of a fraction of a second. Now, there is another reality that is just behind that and and infinity of them before and after that. Each stuck in their own fraction of a fraction of a second. Now, a theory on time travel is that if you could change times, you would actually be in a dimension on that time. Well, things could be done differently. The universe could be the same with only minor change or completely different. It would all depend on the choices each one of us makes in each fraction of a second. Just like now, I could decide to go and move or to study something else. What if I did it in this past fraction of a second in a different reality? Well, then things would be different. So, basically every second offers one to change something, so depending on each dimensions, things could change or not. Brian Green who wrote The Fabric of the Cosmos bring up an experiment that he feels is evidence of a parallel universe. You can even do this at home with just a red laser pointer, a pin, and a piece of paper. The book also explains why he feels that way. I will attempt to tell a bit here, but I would recommend the book as it is great for the non-scientific community. I am not sure where I got these instructions below as I got them a very long time ago and have had them on my computer for an experiment that I did before. But, I will put them here and if anyone has seen this, kindly let me know who wrote it and I will add the correct "who wrote this" for them.
