Steven Gibbs just called me up. I asked him if you can time travel with out a vortex.
He says you need one. Yeah, a vortex opens up a door way. He says you can use an artificial vortex, but they can strand you. People get stuck on the other side.
That is the danger of using em. Also, you can get sent to an alternate earth in a parallel universe.
Steven Gibbs says that going back in time is like living with the Amish, you are gonna party like it's 1699.
I can create an artificial vortex using twin Tesla coils and putting an HDR between em.
