Hi,
I would like to contribute to the conversation. I have a basic university background in the sciences, so I should be able to say somethings worth reading.
Lets look at some semantics first. If time travel is possible, we would need to establish some kind of communication with the distant future to let them know we want them to come visit us. Imagine that we are the time travellers in the future that are waiting for this message from the past. Think about how something from the past communicates with us now. The data that I type here is going to communicate something to everyone on the forum in the very near future. By recording something in the present, we can assume that these records will be available in the future. Communicating with the future is a technology we've been using for a few thousand years. (and built in biologically if we want to get technical, but I'll stay away from the whole biological aspect of time...)
The problem is how we can communicate with the past. The first thing we need to know is how a single particle behaves when motionless (or without time). Wow, what a task! The variables involved in this problem boggle the mind, and I cannot even begin to suggest what would happen. I guess I'll just throw some questions out there and see what kind of answers I get from people with knowledge of experiments related to my questions/suggestions.
If we consider time to be a perpetually moving entity, something moving "faster" than the maximum speed allowed in the present would be propelled into the future. Something moving "slower" than the slowest speed allowed in the present would be repelled into the past. Assuming there are indeed these limits associated with the "present", I've come up with some thoughts.
I've always had the understanding that a complete lack of motion was reflected by absolute zero. Approaching absolute zero would seem to be the slowest speed in the present relative to everything else. The upper limit of speed would be approaching the speed of light... ... (clip)
You know what? I just realized that I have way too many unanswered questions to formulate more precise questions. I would need to see results from experients relating to motion before I can question the way things work. I give up! Time for me to communicate with everyone in the future by hitting the reply button, hehe.
