Hiya BillHicksRules, nice to see you here.
The problem with backwards Time Travel is not about theories, it is about the very fundamentals of human existance.
Do we have Free Will?
Do our decisions/actions affect others?
If you answer yes to either question you have just thrown backwards Time Travel out the window. People like to talk about the 'grandfather paradox'
but that is much much bigger an example that is needed to show the problems with TT. Anything one might do in the past could easily alter history
from that point forward, breath in the wrong place (spread a few 21st Century germs in the past and kill a few people or just alter their lives a
bit), kick a rock from one side of the road to another (that rock later was responsible for the death of a man, now he will not die) and just about
everything else you can do leads to potental problems.
And if you do change anything, then the you that travelled back to the past NEVER EXISTED. If you never existed how could you change the past?
Sure someone with your name and background might exist, but they would not be 'you'.
I do have hopes that we might someday be able to view the past and there are some interesting possibilities for long-range travel. If someone could
for example find a way to 'shift' or otherwise alter a space craft in a Dimensional sense, there is the possibility of travel that takes almost zero
time. In a way that would be travelling 'forward' in time without creating a paradox.
I think you have it exactly right, it is a wierd human obsession but one that is fairly understandable. Who does not have a reget or two?
Plus, it makes for great Drama, in movies and such it can be quite fun.
