After all, everybody knows that someone on Wall Street would NEVER make foolish and ill-considered stock trades!

In my humble opinion, ‘The Eskimo’ has made the most pertinent observation of all the comments.

When you have lived in ‘the future’, and then re-visit ‘the past’, you do know what will occur, you do know those things that will happen, from that point in what is essentially your past, because you have seen them happen. The dilemma is exactly as Eskimo says, no matter how much you want to, warning people of impending disaster or precarious situations is extremely difficult if not practically inconsequential, simply through the warning process itself.
On informing people that an event will occur, and in particular if insisting on it, and people respond to that warning, you will alter the outcome… therefore, no one will see the event as you predicted it, consequently, most people will no longer take any serious notice of subsequent advice you give. In fact the opposite is likely to occur, you will be ridiculed for your inaccuracy. So the course becomes one of abstinence… even total silence.
The reality is that no matter how you may wish it, generally you cannot change an Event from occurring, you can only change the outcome by the navigational path you take through the event.
As a quick example; If you were walking toward an intersection, and a person on the opposite diagonal corner, could see a large truck hurtling out of control toward the intersection, (the event) and yelled to you that it was coming, knowing you are blinded by it due to the large building on your corner obstructing your view, you then have variable choices to ‘navigate’ that event. You cannot stop the truck from speeding through the red light intersection (the event from happening). However, you can choose to stop right where you are and allow the event to happen purely as a disconnected observer. You could choose to peek around the corner carefully and you may feel the wind as the truck rushes by or you may be hit in the face by a flying stone, etcetera. You may choose to make a run for it across the road before the truck reaches the intersection… the outcome here in itself has several variables. You may choose to ignore the warning, and assume it a joke, and continue on your planned path. There are multiple navigational paths for such an event… how you navigate through an event will determine ‘your’ outcome. How multiple people or all people involved choose to navigate an event will determine the ‘whole’ outcome.

People who have lived in or through what we here today classify as ‘the future’ may choose to enter a moment in time (Placement in Time) that we classify as the present, in order to convey a message about a coming event, with the intention of altering the known outcome of that event. If successful, this will not change our future, as we only see our future as it occurs and not only is it the only future we know, but to us it is always our present. However, it will change the future of the person who lives in the moment we perceive as ‘the future’, for they have already lived through one outcome and now their present is changed.

The problem a person might have who has lived in our perceived future, in trying to change the outcome of events that may have a detrimental effect on us, that will occur in our perceived future and their perceived past, may lie purely in our reluctance to believe such person could exist. Therefore, our acceptance of any such warning or suggestion falls on mixed ears, and the desired outcome of the messenger may never occur. This only serves to discredit the messenger further. It is a dilemma of great struggle and frustration… to know what will occur and have no power to change the outcome.

You are all so eager to dive into ‘Time Travel’ yet none of you seem to recognize the agonizing and frustrating burden of such a process. Also you might like to change the phrase… it isn’t ‘Time Travel’… it’s ‘Time Placement’, there is no travel involved in the sense of space and distance. There is no reality of ‘Time’ in a linear sense, it is a dimension of singular existence… it is purely a matter of the placement within that singular existence you are, or wish to be, that puts you in what is classified as ‘a moment in time’.
Travel is something that is traversed through space and distance… it is possible to incorporate travel through space and distance into the re-placement of time, and that is something humanity will accomplish. But certainly not in the placement of time we consider the present, nor the near future. In fact that will not occur until what we would consider now as the year 3335… however, in that time placement, that particular calender system is no longer in use… but I’ll let ‘time’ tell that tale!
