The World's First Time Machine: A Documentary and a Mystery

AI Thread Summary
The documentary "The World's First Time Machine" explores attempts to use lasers for time travel by sending particles back in time. Despite the excitement around the project, there has been no significant progress reported since its release. The discussion references Michio Kaku's "Physics of the Impossible," which suggests that sending particles back in time remains unachievable. Questions arise about how to verify the success of such experiments and the implications of positive results. Overall, the documentary highlights the ongoing intrigue and challenges surrounding the concept of time travel.

I just finished watching a documentary called The World's First Time Machine on youtube about a dude trying to use lasers to send particles back in time. It's kinda old but I'm sure a lot of you have already seen it. I can link it if you want.
But they were acting like the dude was on the brink of making this thing work, yet I haven't heard anything further on it.
Anyone know anything about it or if what he was trying to do is even possible?

I think I remember reading something like this, about particles and time travel, in Physics of the Impossible by Michio Kaku. I think he said they hadn't been able to do it (send them back in time anyway), and as far as I know it's impossible. I'm not sure if it was the same thing, or even if I remember correctly. Either way it was a great book.
 
Just how would you even know if such a thing was a success? You would have to be expecting and looking for the result prior to doing the experiment. And, what would happen if you got a positive result, and then decided not to do the experiment?
 
It was a show on tv from several years ago hyping Ron Mallett's now failed attempt at opening a portal to the future. You can google on him if you want more information. There have also been a number of threads discussing this already.
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
