https://www.sciencealert.com/a-physicist-has-come-up-with-the-maths-to-make-time-travel-plausible
No one has yet managed to travel through time at least to our knowledge but the question of whether or not such a feat would be theoretically possible continues to fascinate scientists. --- ... Copied to Clipboard!

So, if I go back in time and kill Hitler before he committed his atrocities, all of his victims would magically kill themselves? Or would someone else step in for him to avoid the paradox?
This is still nonsense. Nice try, Mr. Physicist. --- Silver Bearings 2020: Clear Vision for America ... Copied to Clipboard!

This demonstrates that when multiple local regions communicate with each other in the presence of CTCs, there is a broad range of communication scenarios which still allow freedom of choice for observers in each region without the development of a logical inconsistency such as a grandfather paradox. --- teep dumb as f*** fr - BatmanvonDoom I'm gonna pound a 400 lb woman just to prove teep wrong - NigerianKnight ...

This has been discussed before. There is a theory that time is immutable. Meaning that even if you change something in the past that history will try to correct itself. This guy just has math to prove that.
Also it would probably make a branch in the time flow making it a parallel universe. There is also the theory that time travel is possible but the farthest back you can go is when the time machine was turned on. Thus breaking a lot of rules we hold dear as at that point time would technically be predetermined. --- ... Copied to Clipboard!

Just to note, this is just a mathematical construct. Perhaps all of reality can be represented by mathematics, but not all mathematics represents reality. This study notes that the theory has no physical equivalent and there is no physical phenomena that is represented by this mathematical framework.

If time traveling created new universes (forks in time), where does that energy come from?
Going back in time doesn't even make sense to me, as if there was a recording in the universe that recorded the previous state of the universe. It's a fun dream, but unlikely. --- ... Copied to Clipboard!

What if going back in time and killing Hitler is part of a larger, meta timeline?
If, in 2025, you use a time machine to go back in time and kill Hitler, you dont create a paradox because Hitler still existed and history wasnt changed until 2025, and your decisions to act only occurred while the original history was still intact? --- #1 Kaiju Fangirl ^_^ https://imgur.com/mptS9Qj ...

You see, we live in the timeline where a time traveler went back in time and killed the Fhrer, trying to prevent WWII.
Time itself fixed it by replacing the Fhrer with a painter. --- GameFAQs isn't going to be merged in with GameSpot or any other site. We're not going to strip out the soul of the site. -CJayC ... Copied to Clipboard!

I see it like this: https://futurama.fandom.com/wiki/Dark_matter_engine " I understand how the engines work now. It came to me in a dream. The engines don't move the ship at all. The ship stays where it is and the engines move the universe around it." Cubert Farnsworth" Just as that explanation is ridiculous, it's the same way I see actual time travel. --- ...
