I believe that nature does not prohibit backwards time travel (if time travel is possible at all) it only has to be perfect to be a true travel back
in time. if not, you run the risk of going into different tangents of the "past" just as if you were to travel into the future, and have different
I think that by your reference to "different tangents' that you're actually referring to different time lines, which have at the moment ZERO proof
of their existance.
So I think for the purpose of this thread that you need to restrict your backwards time travel theories to this single time line.
The reason that linear time travel either from the past to the future or from the future to the past hasn't been observed is for a very simple reason
as I have already mentioned... nature absolutely prohibits it.
For time travel to be permitted into our own past or future (not talking about skipping dimensions or time lines) then we have to admit that the
concept of free will is a complete illusion. Otherwise if we wish to preserve the concept of free will, then we must disallow time travel completely.
Here's a very simple example to illustrate the point.
Lets say that you walk into your lounge room at EXACTLY 5pm, pick up the tv remote control and then toss around in your head which channel to pick.
After a few seconds, you decide on channel 5 ... so far so good ... you've exercised your option of free will and made an independent and unbiased
decision to pick channel 5.
Now lets skip 10 years into the future and somehow you manage to invent the worlds 1st practical time machine. As a test, you jump into it and decide
to travel back into the past to that very day that you chose channel 5. But instead of jumping back to exactly 5pm, you program your machine to take
you back 5 mins earlier and also to appear in another room and not the lounge room.
So you press your buttons and pull your levers and it works, you rematerialize back in the past 5 mins before your previous self walks into the lounge
room for a spot of tv relaxation. You now wait in hiding until your previous self enters the lounge room, sits down and picks up the remote control.
In the meantime you've sneaked unobserved behind yourself whose sitting on the lounge and you watch him (you).
Now here's the problem ... if free will exists, then your previous self should be able to select another channel besides 5, say channel 10 ... and
yet you KNOW he will select channel 5 because that's what YOU selected originally all those many years ago.
It doesn't matter how often you jump back to this earlier time from your future because you will ALWAYS see him select channel 5. In fact, arriving 5
mins before he even picks up the remote, you know EXACTLY which channel he will pick ... so therefore FREE WILL on his part was simply an illusion and
he was predestined to select channel 5 and will always do no matter how many times you observe him.
So there's the problem ... allow time travel and you have to admit that free will doesn't exist and EVERYTHING is therefore scripted and you follow
that script slavishly.
Otherwise, retain free will and give up time travel.
It has to be one or the other ... so tell me, which appeals most to you ?
