I fear our conversation is in danger of turning due to an effect that is quite common on these boards. I realize what I’m saying is quite hard to swallow and it causes debate, weather serious or entertaining. It is even more difficult when you come into the middle of a conversation or a series of questions that are a few weeks old.
Your points are all quite valid and I have discussed them at length on this and other boards for quite a while. I do not wish to antagonize you however, we both know the Tippler cylinder is only a thought experiment to explain the very real physics behind Kerr black holes. As to your other comments, again, they are all true as defined by the limits of spacelike trips on single worldlines. It does not account for travel between worldlines.
I have never claimed to be a physicist or an expert on what the CERN laboratory is doing at any given moment so I feel it is pointless to argue about what they may be doing in the future or what “breakthroughs” they will or might have. My comments about the CERN lab are in reference to particle accelerators in general and other questions that have come up in the past. The major physics break through for controlled gravity distortion does happen at CERN in your future. Heck, we haven’t even touched on “Z” field compression yet.
I suppose I could say that I was the one that traveled in time and convinced them to change their experiments but even I would have a hard time believing that one and I do not wish to insult your intelligence.
Just curious…what is it that interests you about time travel?
