: What's a tardis ? : I'm trying to figure out how to open a wormhole...I can tell you a little if you'd like to know. It's pretty simple actually- all you have to do is take all the space out from a volume and you have one mouth of a wormhole! Similarly, you can make another mouth. The problem is getting the two connected. In reality it will turn out to be very simple. The only problem is in our perception of how things work in nature. : The Casimir effect in a supercooled environment gets rid of most of the space in a volume... can you guess why?

Does it condense it like what happens when things freeze?
