Marty McFly and Einstein’s equations - new research shows paradox free time travel is possible

article image placeholderYoung physicist 'squares the numbers' on time travel
I would love to hear what you think about the science or even just a science fiction of it. What does it do to your faith movie plot which has time travel in it? Let me know

For those of you who want to dig deeper and read up the actual physics paper, I am adding a link here

That outcome is always the outcome, or else there would have been no Marty McFly in the first place to go back. So that was kind of the whole thing. And I love time travel films, so I don't let these things get in the way. But there really never is any stakes unless you're somehow going to, I guess maybe an alternate timeline. I don't know. But even if we go back to that with the Terminator, let's say that was your only success

Does this mean...

Okay. Question, if I'm understanding this correctly, does that mean that if time travel existed and you went back, there would be no point in trying to change anything because it's going to recalibrate, right. So you could go back in time and just visit. But you're not going to really affect the outcome of anything. Is that a correct conclusion

And whatever disruptions they caused were simply part of the past. As we knew it is how I get this. This is why I've always made the arguments that I made that the Terminator always fails because John Connor was alive to fight Skynet in the future. And then I was always told that I was stupid, which I'm totally open to that idea

Local free will is possible without paradoxes in time travel

Hi seeking plumb. An average Yo. Yes, seeking plumb. You are right. That's how it would appear. It's not that you will not be able to change anything. It's that you will be able to make changes. And that's actually something the paper talks about
