A wormhole is functionally a tunnel that connects two separate points of spacetime. Wormholes can allow for extremely fast travel by creating a tunnel that is shorter than the distance would otherwise be between the two points. This can create situations where humans can, effectively, travel faster than light without ever truly breaking light speed.
Wormhole generators were invented in 2038, though were not traversable due to the generated wormhole’s instability. Various tests were done with unmanned drones and regardless of how brief the trip, the wormholes didn’t allow for the drones to complete the trips. Thus wormhole advancements stagnated as funding dried up after thirty years of unsuccessful attempts to discover a way to make it a viable method of transit. For another eighteen years, no real progress was made.
In 2089, Silvia Lumo discovered a way to interact with and pressurize dark matter. This discovery allowed her to get a grant to do further research, where she and a team of scientists discovered a way to use the exotic matter created by this process in order to create stabilizers for both sides of a wormhole.
With this advancement, humanity has begun exploring further and further into space, allowing us to know more about the universe as time goes on.
