wormholes

[Shirt_Ninja_13]

Does anyone know what, if anything, wormholes are made of? A friend of mine asked this question, recently, and I said that I don’t think they’re made of anything in particular (warped space-time, maybe, but that seems like a non-answer), but I figured I’d ask you guys and see if anyone could come up with a better answer.

So how about it? What are wormholes made of?

Wormholes are a theoretical concept that General Relativity allows. Assuming you can find negative matter. Here’s a neat paper for you.

Wormholes are analytical solutions of the Einstein field equations, and basically represent short-
cuts in spacetime. By now, wormholes are theoretical entities and we can speculate but not rely on
their possible existence. A key point is that to keep wormholes open, preventing them for pinching
off towards a singularity, one has to thread them with exotic matter.
