The latest approach has been to "curve" space around the ship so the light rays curve around it and re-emerge on the other side. This is done by an artificial gravity field surounding the ship that bends the space accordingly.
This technology is only theoretical. No working models are in existence to date, but research is continuing in this field despite early failures.
The second test involved an unmanned ship, equipped with sensors and radio and other equipment, staying in constant contact with the observing science vessels. However, the gravitational field was incorrectly configured and the ship was "swallowed up" into a pocket of space, as the three - dimensional space closed around it entirely. No light, radio waves, or any objects could be sent to or from the ship, and it was considered lost forever.
Other techniques, such as absorbing and re-emitting the light and other radiation, have been discussed as being theoretically possible, but nothing else has been physically tested in the past several years.
However, research is still continuing in this area . . .
