Super strong materials
As it is mentioned before, the Element Zero “alloys” would form strong temporary bonds when the positive electrical charge is attached to the alloy. Because the Element Zero Alloy is 100,000 times harder than one of the hardest thing on the Earth, diamond, Element Zero Alloy would be a good choice for interstellar trip which requires speed that is as fast as light. There are enormous numbers of asteroids in the universe, so the space cruisers needs extremely hard surface to protect them from being hit by the asteroids.
