Scientists think the glass was fused in a meteoritic impact 30 million years ago, making it rare and luminous enough to befit a king..科学家认为这种玻璃是由3000万年前的陨石冲击地面融溶而成，它的珍稀和光亮足以适用于国王。

A mixture of meteoritic water and cometary water would not work either because this combination would still contain a higher concentration of deuterium than is found in the oceans..陨星水和彗星水的混合也不可能提供地球上的全部水源，因为这种混合水与现在的海水相比，仍然有着较高的。
