Doctor Who celebrates 46 years of Time Travel on the BBC.

“Viewers first encountered The Doctor’s ship, the Tardis (Time and Relative Dimensions in Space) in a junkyard as the Doctor headed out in London. The interior of the time-space traveling craft is dimensionally transcendental and exists in its own universe — allowing the ship to be bigger on the inside than its outer shell.”

I’ve always loved how the TARDIS is a living being.  The Doctor says that they are “grown, not built,” and like all sentient beings it is bigger on the inside than it is outside.  The mind is limitless, even as man is limited.

Here’s to another 46 years.
