White holes: Do black holes have mirror images?
These black hole opposites would spew energy, be impossible to enter, and might even answer some of the universe’s fundamental questions.

It was no less a luminary than Isaac Newton who taught us that for every action, there is an equal and opposite reaction. Push on the wall, and it pushes back. With that in mind, cosmic “white holes” make a lot of sense — they seem inevitable, even.

We all know about black holes, those cosmic vacuum cleaners that suck in anything (including light) that gets too close. Well, what about the opposite? Might the vast unending cosmos also feature white holes, which emit matter and energy into the void, but could never be entered?

It’s appealing to our sense that things often come in binaries — if there’s an off switch, there’s probably an on switch somewhere. And white holes also feel like a necessary balance to the finality of black holes: Where does all that sucked-up stuff go?

Unfortunately, whether or not white holes truly exist remains an open question. But that hasn’t stopped researchers from thinking about what they’d be like if they do exist. Some theories suggest they might even be necessary to solve some longstanding problems, from the nature of dark matter to the nature of the universe itself.
