Internet search engine that searches the future? A crazy notion? Hehey. "Let's do the time loop again!"

It tears a hole in the fabric of linear thinking. There is no way to understand how the time loop effect would work in our cause and effect consciousness. No doubt powerful secret military forces would fund the device and try to use it for the ends of evil empire.
The original thought experiment envisioned powerful lasers angled to create a vortex of particles. As in a black hole the tachyons caught in the vortex would exceed the speed of light, emerging from the vortex in the past.
And sending an internet encoded stream of tachyons through the vortex would send internet signals from the future back to our present time.
So theoretically a google search query, complete with date, entered now, would then be cached and when that date came around the query would then be entered in google, the results then sent back through the tachyon stream to the present, appearing instantly just like google works now.
Of course the search reply would need to be sent to the satelite orbiting the sun, at that future date, then back to earth, taking a few minutes either way. It takes the light from the sun 9 minutes to get here.
The reason for the solar radiation is that it would take titanic forces to create the vortex, that was the problem with the physicist's original time vortex thought experiment. no lasers powerful enough could be built with the meager energy resources existing here on earth.
With plenty of gamma rays (protons) reflected to create a vortex, available in limitless quantities near the sun (not so close as to vaporize the satelite/device), a vortex of with sufficient acceleration should be possible. But what to make the device out of, that won't just vaporize?
Molecular engineering is most likely the answer, materials built up from the nano level with DNA? Like bucky balls, but intentionally designed.
