Yes, I realize people become hostile. I don’t expect anyone to believe me and I have nothing to sell. I take no offense by it. Just out of curiosity, if you were a time traveler, what do you think it would take to get people to believe you?
I suppose we could agree that no particular era in history is famous for its development of humanity but just once I would like to hear questions like, “What is family life like in the future? How does society deal with poverty? Is AIDS, abortion and drug use still a problem?”
Why don’t I give you a stock tip? The money you make would dilute the intelligence and forethought that a smart person had in picking the stock all by themselves. If I told you how to get rich, I would be taking money from them and giving it to you.
Getting back to my “proper” universe is tricky but possible. Yes, another jump would take me to a different family.
Cement block…good question. The hard part of traveling to other world lines is just that. There is a system of clocks and gravity sensors that sample the environment before dropping out. Its called VGL, (variable gravity lock). If a cement block were there, the machine would “backtrack” until it sensed relative congruity to the original gravity sample. A great deal of time and effort goes into picking just the right spot since you can not physically move during a displacement.
