Brief Description

Project Paradox was all about sending things back in time by accelerating one wormhole to relativistic speeds while the other remained stationary. The experiment was conducted in the year 2855.

Explanation

Before going in-depth, imagine 2 wormholes. One in 2020 and the other in 2020. Things moving very fast appear to move through time slower to external observers. If one of the wormholes (A) was accelerated for a long time then brought to a rest, its clock would read, for example, 2021 while the wormhole at a rest would read 2025 (B). Theoretically, someone entering the wormhole that was at a rest would pop out in the year 2021. They could even see themselves enter the wormhole if they waited 4 years. Or, someone could enter the speeding wormhole to travel to the future.

The Experiment

Setup: A very small wormhole (on the scale of a few nanometers) created by feeding exotic matter into quantum fluctuations was to be accelerated to 5% the speed of the light and brought back to the Sol system, enough to cause a few seconds of time dilation. The other would be waiting in the Sol system until then. Wormhole A was sent to speed and wormhole B was not moved at all.

Once this was set up, a small particle was detected exiting wormhole A. A few seconds later, the particle was sent into wormhole B.

One thing that was not tried was waiting for the particle to go through then not fire the particle through, but many are hesitant to try this, in fear of breaking the fabric of space-time.

What's happening now

Scientists are currently on the hunt for larger wormholes, and are developing techniques to keep them stable and get them to relativistic speeds quickly. More experiments are to be conducted.
