Glass In Spaaaaace

Posted by Zonk on from the microgravity-for-macrogains dept.

AnKsT wrote to mention an article on NASA's site about creating and manipulating glass in space. From the article: "In microgravity...you don't need a container. In Day's initial experiments, the melt--a molten droplet about 1/4 inch in diameter--was held in place inside a hot furnace simply by the pressure of sound waves emitted by an acoustic levitator. With that acoustic levitator, explains Day, 'we could melt and cool and melt and cool a molten droplet without letting it touch anything.' As Day had hoped, containerless processing produced a better glass. To his surprise, though, the glass was of even higher quality than theory had predicted."

    Something in the Bible predicted something else in the Bible? That doesn't make the Bible true, it makes it internally consistent (but I have doubts about that as well). I'm not surprised that your name is "CrazyJim" because you're just another insane Christian crank.
