light speed = 0 ???

Recent ultra-cold temperature physics research has led to the abiity to slow and even stop light. Not absorb it, reflect it, or transform it, but actually stop it.

Very cool.

Exceeding lightspeed, science, not fiction

Under some circumstances, scientists in recent years have exceeded c, the speed of light in space. The research has been reproduced, and has someting to do with quantum tunneling. So what has been breaking lightspeed? Well, light itself! But don't ask me to explain it -- read the article.
