The "lightships", UFO:s and time machines 1) What could be the mysterious light at the outer layer of some saucer-shaped craft? Could it be some kind of protective field, what is created by laser-rays Why some saucer-shaped craft would have strange light in the outer layer? That strange but bright light would be the signal, that the craft is covered by the protective field. One of the theoretical simplest ways to make a protective field around the space- or aircraft is simply to put the lasers on the core. Those lasers would be close to together, and they would send their laser-rays in the same line with the layer. If something would hit to those laser rays, they would vaporize it before the solid particles are hitting the layer of the craft. That system requires only the "ports" where the laser rays would send over the layer, and that system can be made by using optic fiber, which allows that the laser ports are close enough that the bullets c...
