Count Zero's entry in the avatar contest this week got me thinking: How much does the TARDIS weigh?
We've often seen the TARDIS moved from one place to the other. The picture above was taken from the First Season episode Marco Polo which is set in the 13th Century. How the hell did they lift the TARDIS? They didn't have heavy machinery and I doubt a couple of sherpas could lift it. So does the whole bigger on the inside bit transfer to weighs more on the inside?
Thoughts?
