Wormholes could blast out blazing hot plasma at incredible speeds

Wormholes that are surrounded by matter, like the ring that gathers around a black hole, could create strange rotating clouds of hot plasma. Anything that falls in one end could shoot out the other at 200 million kilometres per hour, or even faster if the wormhole is enormous.

A wormhole is a tunnel between two locations in space-time. The simplest versions of these hypothetical objects have black holes as “mouths” on either end of the throat connecting them – nothing…
