I will try to answer all of your questions however, I have noticed that there seems to be a difficulty in entering a conversation in the middle. Most of the following questions I have answered at length in previous posts. I understand how important it is to have these answers when new people read portions of the posting but I find it tiring to keep repeating myself. Any suggestions would be appreciated.
(I was just wondering who won the Super Bowl in the year 2001?)
I do not answer questions like this. Although I don’t really know the motivation for the question…I can guess. If a time traveler had knowledge of your future, and you could only ask one question, would this be it? Besides, can you tell me if it rained in New York on June 4th 1932? You are from their future so should you know that?
(I have read some of the concourse up to the end of this topic’s dialogue…. 1. If your machine is capable of traveling back through time from future earth to now, I wonder how your vehicle landed on this earth at all? You obviously know that this earth and your earth do not occupy the same quadrant of space…. You would also need a life support system to sustain you until you were within earth’s atmosphere… and lastly the avoidance of man made structures…)
This is actually a very good question that parts and pieces of the answer are scattered around in previous postings. I am often surprised that it is not the first one asked. You are correct, this problem is actually the most difficult part of time travel. Although some of your assumptions about matter displacement are a bit off, the problem is real. Inside the displacement unit are a series of very sensitive clocks and gravity sensors. This system is called the VGL (variable gravity lock). In simple terms, before the unit “leaves” a world line, it takes a base reading of the local gravity and adjusts the Tipler sinusoid to “lock” into that position. Although the tmporal physics of this statment are wrong, in effect, it holds you to the “Earth”. During travel, it periodically checks to see that the field has not varied. If it does, it stops and reverses course or drops out at that point. Buildings and other terrain features are avoided in the same way. Yes, we do bring oxygen in the vehicle with us but we do not lose atmospheric pressure.
(Pamela seemed concerned with the ‘go nowhere ripple effect’ that might occur when a time machine left and then returned, but I find even that logic flawed. I maintain that a time machine would imprint itself spatially upon a certain time period.)
I’m not sure what you mean by imprint?
(Einstein’s Theory of Relativity would dictate that even if you left in such a machine for two minutes, this time would continue to advance and this world would still move through space and rotate.)
Yes that is correct.
(Therefore a time machine would NOT appear to stand still but rather would (depending upon the time interval) appear to suddenly defy gravity as it disappeared and then, free of the gravitational momentum, would reappear in near or far space.)
Please see VGL system above. Also, please be aware that from the viewpoint of the time traveler, the displacement unit actually left and then returned. The viewer does not experience this. Think of it as a Gosub statement in a computer program.
