Steven Gibbs told me that he travel (not time travel) to Calgary Canada where John Tooker (not related to John Titor) taught him how to build a time portal.
Basically, the time portal Steven Gibbs learn to build is PVC pipe with copper wire wrapped around it in a caduceus coil conformation. With the John Tooker time portal you could possibly even see the dinosaurs. This is supposed to create a dimensional doorway into another world. For example, like in the movie Coraline, where a little girl finds a door that allows her to travel to a parallel world that looks almost like her own. A world with an other mother and a funny father. The time portal is supposed to be used to allow people to create these dimensional doorways to an Alternate Earth.
