video loop 50 sec., chemical reaction Reaction of permanganate and glycerine. Flash that occurs after the oxidation of glycerol and auto ignition of the whole compound. A number of stars changes to burning torch for short time, just after the exhaustion of stocks of nuclear fuel. Intense fall of stellar material may in fact lead to shock wave and thus re-explosion of star corethe supernova explosion. During this explosion the star shines shortly as strong as the entire galaxy. Figuratively speaking, the star literally turns upside down and most of its material disperses into the interstellar space. From the expanding supernova remains tiny, very thick and fast rotating residue. The weight of the residue is not such as to collapse into a black hole. A body is created, that is except for a thin millimetre atmosphere, composed mostly of neutrons. In other words, conventional matter for example, as on Earth very thin “sponge”.
