The idea is by firing a particle through a cone shaped network of lasers, so that the particle speeds up (from the observers point of view) and goes faster than the speed of light from the observers point of view, dissappearing from sight. It is theorised that the particle will travel back in time to an earlier moment of when the time machine was active. And it is thinkable that codes could be send back through time by means of an array of dechiparable particles.
There is a flaw however with the theory in my opinion. I think it's unlikely that it is possible to send particles back in time this way, and ever more likely that time slows down to zero from the observers point of view, effectively locking the particle inside the loop. And the more particles they will send, the more particles will build up appearing stuck in the vortex.
However from the particles point of view, the particle will go through the spiral at the speed of light and leaves/dissappates at the end as if no time distortion happened. That time distortion, in my opinion, will probably cause for some really cool looking light effects, but it probably won't break zero time.
Still it's an interesting experiment, because it will be the first time we would be able to test as the observer in Einstein's theory at speeds of light for the first time in history.
Do you think the idea has actual merit, or do you think it's a fairytale dream, like I think it is?
