In 1905, an asker posed this question: "Can matter be transformed into energy?"

One answer said, "No, because both matter and energy are conserved, as basic principles of physics."

Some other guy, named Einstein, wrote a long essay on something called "relativity", containing a formula "e = mc^2", which he says allows matter to be transformed into energy.

No best answer was picked, so it went into voting. After several days, which answer do you think was chosen as best, and why?

In addition to the previous question about splitting the Hydrogen from Water, some people mentioned electrolysis. My husband thinks that just as fuel and air are compressed to create the movement in pistons in an engine, that Hydrogen in its pure form could be harnessed to do the same thing. One would have to incorporate the electrolysis process into the engine. What do you think of the possibilities of that?

Obsidian that I have found has always been black or black/red. I found an unusual piece that I believe could be clear obsidian-this is my best guess. I just never heard of completely clear obsidian.
