Recently, there has been a lot of hoopla over the apparent discovery that some neutrinos travel faster than light. In other words, Einstein is passé. This has all kinds of sci-fi implications, including the theoretical possibility of traveling backward in time.
Now, I’m no theoretical (or any other kind) of physicist, but I am skeptical, for two reasons. First, it’s not every day that a scientist gets to overthrow the laws of physics. I’m not discounting the possibility that someone might out-Einstein Einstein, but it must be on the basis of a whole lot of experiments with pretty convincing results. Second, there is a whole slew of errors that might account for the results.
To their credit, the scientists who had observed these results were so baffled themselves that they announced them, inviting the world’s scientific community to pitch in and find any and all errors. In other words, unlike other folks, they have scientific integrity, and know that science is never “in.”
