Time can flow backwards

Does it get much more Bizarro World than this?

In a distant galaxy, a star unexplodes. Just moments ago a shell of tortured matter was flying together at 30 000 kilometres a second. Now it has become a star, and the last shreds of glowing debris are being sucked in. With the explosion undone, the star begins the long journey back to the time when it will be unborn into the gas and dust of an interstellar cloud.

Is someone running the film backwards for comic effect? Not necessarily. In a paper published in the last week of 1999, Lawrence Schulman of Clarkson University in Potsdam, New York dropped a bombshell. He showed that regions where time flows in the normal direction can coexist with regions where it flows backwards. There could be places, perhaps even within our Galaxy, where stars unexplode, eggs unbreak and living things grow younger with every second.
