Proof the wormhole in 'Interstellar' looks legit

In Chris Nolan's sci-fi epic Interstellar, the director employs lots of high-concept science, including the idea of wormholes.

In the film, (spoilers ahead) Matthew McConaughey's Cooper, and his NASA team, travel through a wormhole to try and find a new planet to house their fellow earthlings.

Sounds pretty crazy, but Nolan didn't just pull this scientific concept out of thin air. (Well...) He consulted with renowned physicist Kip Thorne, among others, to make sure he got the hard science pretty right.

In a Discover Channel special, narrated by McConaughey, Thorne explains a little more about wormholes:
"Einstein's relativistic laws... say that wormholes could exist. (Wormholes are) a particular way that space and time can be curved. Like adding a little tube that connects two parts of space."
The trick to hypothetically traveling via wormhole, is to stop the thing from closing. More from Thorne:
"In order to hold a wormhole open... you have to have the wormhole threaded by a negative mass... It can exist, and has been created in laboratories in very small amounts."
During the filmmaking process, Thorne sent some equations for a pretend wormhole that could be theoretically traveled through, to the Interstellar visual team Double Negative. That team simulated the wormhole exactly as the equations suggested, because apparently that's possible.
"(Nolan and I) discussed how big the wormhole should be and agreed that it should be just barely big enough that it should be seen from earth through the bending of light around the wormhole.
As for what happens in the last hour of Interstellar, with all of the fifth-dimensional beings, you're going to have to read the book for that.

But for now, until it's pulled from YouTube, you can watch the Interstellar Discovery special online:
