Just a guess here, but I'm thinking probably mostly quartz. It looks as if it has spent some time in a river. Milky quartz can take on a glassy appearance when wet.

OH! really you are stating your opinion as if it were factual, you do not know if the universe has an edge or not and until you do it is just at best speculation on your part?Actually, I agree with him. In his defense he did say "according to theory", which is a pretty accurate statement as far as I know. Further, he might been better off saying that the comment was over-reaching in its implication rather than flat-out wrong, but again I agree with him. Almost any analogy can work in-so-far as its intended breadth and depth; however, any analogy can be extended beyond the original intent of the person who made the analogy, and in this extension become false or outright ridiculous. This is a common structure for an argument similar to reductio ad absurdum arguments. "Well if electricity works like water... I should be able to swim in it... but I can't, so therefore this analogy is flawed." This is a classic example of an analogy simply being taken much too far. The most basic principles of electricity do very much resemble water as all the basic components are there. Pressure to voltage, current to rate of flow, resistance to resistance, etc... but even this analogy breaks down past a certain point.
