Question: How does a worm hole form

Alexander Burke answered on 7 Mar 2018:

Good question. To be honest with you, we don’t really know. Wormholes are not very well understood but I will try my best to answer your question.

There are two wormholes which I know of. One of which is a normal wormhole and the other being a “Kerr wormhole”. A Kerr black hole is a spinning black hole, theory suggests that if you fall into a spinning black hole you would be spat out in a totally different universe. This is sort of like a wormhole since you enter through a tunnel and appear in a completely different universe. So, to answer your question, a spinning black hole gives rise to a wormhole. It’s just a shame that you would be destroyed before you entered the wormhole… and what is left of you will be spat out of a white hole into a different universe.

As Hermine said, normal wormholes are theorized to form through quantum mechanics. Quantum Physicists (string theorists) suggest that when two types of particles interact with each other, through a process called entanglement (outside the scope of this question), then they can give rise to wormholes. Now, wormholes are very dynamical objects… they open and close constantly so it’s very hard to travel through them. The only way to hold a wormhole open (crediting Kip Thorne) is to use exotic matter (objects with negative mass… weird) to forcibly hold them open. Again, this is not very well understood. This is the cool thing about being a scientist though! You can sit and wonder about these amazing things!
