### Zefram

I was reading this article by John Cramer (those are usually pretty out there) and I noticed that the references (and probably the article itself) are from the '80s. I then found that this stuff is mentioned in the World of Physics. So what's the state of this idea today? Any possible connection to the accelerating expansion of the universe? Or any other interesting tidbits?
