A question worth considering is: has anyone thought about creating a time machine based on a particle accelerator? Pushing matter about a cyclotron like at the LHC, could create time-dilation for matter (like a neutron), as it is being flung around in a circular path near the speed of light. It should be noted that matter will not reach or exceed the speed of light.
Prof. Ronald Mallett‘s theoretical research shows that light and not just matter could effect gravity. Professor Mallett has proposed creating a machine which circulates laser beams to create space-time dragging for an elementary particle. Creating a ring of light, in a cyclotron-like machine will create a gravitational drag effect, this will be noticeable for small elementary particles, such as a neutron [Footnote 1]. However the machine will not have an effect on any other matter outside of the apparatus itself. The function of time-dragging will operate within the local reference frame of the matter trapped within a cyclotron stream. This does not make a time machine for an external observer, but will create time dilation effect on matter caught in the light-stream’s drag.
So how does one make a time-machine? Understanding space (space-time) is an important part of this puzzle. Just as matter can’t break the light barrier, neither can matter reach a temperature of absolute zero. So what else can one do? Create a massive gravitational body, engineer a magnetar using a stellar-manipulator, possibly, but technology to create this is theoretical, and most likely won’t be feasible for hundreds, thousands or even hundreds of thousands of years. There are however other more practical solutions which we could use to build a working time machine in the 21st century. Continue reading
