Since the universe is so huge, most astronomers think that there must be a planet, somewhere out there, similar to Earth. But a computer model created at Sweden’s Uppsala University says that our planet may in fact be the only one supporting life.

The machine came up with a concrete number of what we already knew. There are about 700 quintillion planets, or 7 followed by 20 zeros.

The unexpected by-product of the calculation was that Earth may be unique, actually an aberration among myriads of dead, uninhabitable worlds.
