10 Real Things That Prove Doctor Who Exists

10. A Crack In Time And Space

The fine folks over at NASA are always finding oddities and amazing sights in the great wide universe, and back in 2006, they discovered this potentially hazardous link to one of Doctor Who's most famous series arcs.

When observing infrared images from the Spitzer Space Telescope, astronomers noticed a strange shape. It was long and spindly, winding around like a large black snake. After much science was done, it was discovered that this is the core of a huge dark cloud that could, and we quote, "swallow dozens of solar systems."

This dark snake doesn't look a million miles away from the crack that Amelia Pond found on her bedroom wall. That particular crack turned out to be a gateway to an Atraxi prison, and other tears would reappear throughout the series before the universe was ended – and then rebooted – in The Pandorica Opens/The Big Bang.

Like NASA's discovery, the cracks in Doctor Who were also capable of swallowing things they came into contact with, such as Scottish parents, or dead nurses.

If such a thing also exists in our own reality, does that mean the end of the universe is nigh? Let's hope not.
