Not traveling back in time. No one from the future has done it.

Never. Visiting the future (at a faster pace than usual) in some definition or another may be at some point, but that's the extent of it.
Memories last forever, make them while you can.

Never. I don't either believe that time is a thing. But there are smarter people than me that argue.

It absolutely will be.

Would you go back in time and kill Hitler as a child? It would save millions of lives of those who perished in the holocaust, but would simultaneously eliminate millions of people alive today whose parents would never have met, likely including you. Of course if you don’t exist you could never have travelled back in time to kill Hitler....

From a chassidus/kabbala perspective, the past and future do not exist (aside for their affect on the present). So although it is possible to change the past (by changing the way it impacts the present) time travel as popularly understood is not possible.

Unless when you go back you go into a different timeline that's independent of this one.

If you look at life like a comic strip, or any book for that matter, it may help. You can read the book in any order, flip to the end, do as you wish, but it will have no bearing on the actual story. Being able to see the future doesn't mean you have the power to change it. G-d may very well have that power, but we are told he doesn't exercise it, as we have free will.

  • Location: The value of a forum such as this one is not in that one can post a question and receive an answer, but in that the question has most likely been asked before, and the answer is available to him that will but only use the search function.
  • Programs: 1. Search on google. 2. Search in the right board of DDF with a general word or two. 3. Read the wiki. 4. Read the thread. 5. Ask away.

If there are an infinite number of timelines representing all of the possible choices that were made in history, why bother going back to another timeline? You will simply be creating two new timelines- one where you chose to go back, and the other where you chose not to...

And this answer is satisfactory to you?

It’s much more complex than that. As the Rambam says, and the Tanya and others discuss  הוא המדע והוא היודע והוא הידוע
Hashem’s knowledge is itself the existence of all of creation; it is not separated in any way from Him. For anything to have an existence it must be his ידיעה that gives it its existence. He “knows” everything in existence simply by knowing Himself. He, and therefore his ידיעה transcend time. He created time but is not bound by time, therefore his ידיעה (“right now” from a human perspective) encompasses all points in time from the beginning of time until it’s very end, giving everything across all time it’s existence. To say that he doesn’t know at one point in time what is transpiring in another point in time is to to not understand His relationship to time. Since He necessarily “knows” what is taking place across all time, since that is what gives existence to all of creation across all time,  that knowledge creates the reality, seemingly leaving no room for any other possibilities. That is the problem.
