Our Pilot drops Angel's hair as a rubbish dump. He was friendly. And he communicates with us clearly, and tells us a lot. Angel's hair is something scientific which is practically mass-less, and it evaporates. Throughout the book communication with aliens is through long distance, they are friendly. But they are spirits, not primitive solid persons. Their society is a population of transparent spirits. De-materialisation, is the process whereby one of their spacecraft suddenly disappears completely. De-materialisation also happens when an alien spaceship intentionally dives rapidly towards the ground, but there is no crash as it has disappeared. Where did it go? Re-materialisation is when they make something reappear, as they do often. It is to them an ancient technology, but they explain it. Two very strange aliens are about 2 foot tall, humanoids, but their bodies are invisible and their heads are invisible spheres with 20 eyes. Eyes which change shape and grow so quickly, that they swirl. They are friendly teachers at a foreign University, and they tell us a lot! They show us some experiments we didn't understand that well with strange liquids, but they can even tell us of strange flights. Aliens have found a new dimension of scientific knowledge when they discovered that they can make spirits grow and grow. Spirits are living and growing. The greatest discovery for us, was that a tiny sample of a spirit can be implanted into an egg embryo, to grow as a tiny transparent and utterly invisible seed inside the embryo, and therefore the invisible spirit grows larger and larger, it shall open the most important of all new fields of science. Understanding what a spirit is, they have put their spirit into eggs. And say, because they have put their spirit into an egg they will never die. Over millions of years, they have done research to increase the speed at which they think and move, and through long research, they have discovered many ways of improving their speed millions of times with every breakthrough. They think at least billions of times faster than we do, and tell us incredible things about time rates being relative. They have created almost mass-less fields of forces, which can be woven into a fine very detailed structure. It was natural that later, they wanted to create life from it. The life created is almost weightless, it becomes the possession of their spirit, and all of them move at incredibly high speed. To explain De-materialisation, you need to think that empty space is a thin surface which matter sticks to and adheres to. They said the normal force of adhesion is about 184 tonnes to the square inch. But they avoid strong forces that might tear something, by using gentle catalyst particles. A thick cloud of neutrinos cooled to absolute zero, forms a gel which has the key to unlock the sticky adhesion of matter to space, so that it may leave space. Above the surface we call empty space there is a different space, and then yet another different space again further than that, if they want to travel higher. To cause De-materialisation, a spaceship creates a dense cloud of ultra cold neutrinos, catalyst particles which needs to penetrate their aircraft completely. It gently is unlocked from from empty space, it will lose its stickiness for a moment, and a negative electrostatic charge lifts everything away off space. It vanishes completely. Unknown to us empty space carries a negative electric charge, even where there is no electrons at all. A static charge applied to the whole spacecraft holds it up in that dimension where you can't see it, and it is sometimes hovering merely a few inches up though it has vanished. To Re-materialise, (and then to reappear as if from nowhere) they gently decrease the static charge, and the spaceship gently lowers towards empty space, and returns to empty space, and as it does so it may push air molecules aside harmlessly.
