BABlogee Doris Bailey sent me a link to an article about a physicist who is trying to send signals backward in time.
I can’t add much to the article; it’s written well enough that you’ll figure out what it’s saying. But man, it’s weird stuff. I’ll be interested to see how his experiment turns out. Of course, if it works, he should be able to tell himself it worked by sending a message back to when he first started his experiment. So if it works, we’ll know sooner than we think!
