But wormholes are connected to black holes, not magnetars:p
Do you have any proof?
Here, read this ---> http://www.federalspace.ru/185/:
The main difference between a "wormhole" and a model with a black hole will be the absence of an event horizon. That is, matter entering the tunnel does not disappear for an external observer. It may leak out of our part of the Universe and flow into it. If the tunnels are open, this will greatly expand our capabilities for exploring and even mastering the Universe. As already noted, the entrance to a "wormhole" has its own characteristics. By observing an object falling onto a planet or star, at the moment of contact with their surfaces, we will be able to observe a flash of radiation and thereby record this phenomenon. In the case of a black hole, the same object falling onto it will simply disappear.
This is exactly about the differences between the "wormhole" case and the black hole case.
