My friend is presenting at an academic conference in April on DMT and the DMT-Nexus. She's been looking for information on the use of the word hyperspace in relation to the DMT experience, but has been having a difficult time hunting down concrete information. Does anyone know anything about this? Was Terence McKenna the first person to use the term in relation to DMT, or did he just popularize it? So far the most useful thing she's found is an excerpt from "The Science of Battlestar Galactica":
Hyperspace
What about hyperspace? A common device used in science fiction and science fantasy depends upon the existence of an alternate realm where space is "denser" and the speed of light is not a speed limit, or perhaps there is no speed limit at all--hyperspace. A spacecraft enters hyperspace through its own or by external means (by using a jump gate versus a jump point in Babylon 5 terminology), it travels rapidly to the destination, and reenters "normal" space. Such a dimension has been called hyperspace (Babylon 5, Star Wars, and others), subspace (Star Trek, though the plot device is used for superluminal communications only), or slipspace (Star Trek: Voyager, Andromeda, Doctor Who, and the Halo series of video games). When the concept of hyperspatial travel initially appeared in 1930s science fiction, there was no corresponding science to explain it. It was a dramatic conceit. Comparatively recent models of the structure of our universe may provide a dramatically satisfying post hoc explanation for hyperspace.
The notion that there may be parallel universes coexisting simultaneously has been a frequently used devise in science fiction, though the concept of multiple universes and/or multiple realities goes back much further and can be found in ancient Hindu writings. Parallel universes have been generally depicted two different ways in science fiction. In one case, a parallel universe is a universe that is almost exactly like ours, but where some small deviations in history have propagated to create dramatic differences. In other cases a parallel universe is a distinct universe that exists adjoining to our own--like E Space and N Space in Doctor Who, or fluidic space in Star Trek: Voyager. Hyperspace relies on the second type.
Recent advances in superstring theory, specifically a concept called brane cosmology, hint at the existence of hyperspace. The fundamental premise of brane cosmology is that our four-dimensional space-time may be one of many (normally) disconnected universes separated by some sort of membrane, or "brane." In other words, our four-dimensional universe is one of many that coexist simultaneously within a five-dimensional space known as the Bulk. Scientists have proposed cosmological brane models that suggest that interactions with neighboring branes may explain the weakness of gravity (compared to other fundamental forces). One scenario, called the ekpyrotic universe, is based upon the hypothesis that our observable universe came into being when two branes collided. Together, all the parallel universes along with the Bulk form what has been called the multiverse.
Think of the multiverse as a huge apartment/condo/co-op building. Our own universe, and every other universe, would be like individual apartments in that larger structure. Suppose we live in universe 4D and we want to go from the bedroom into the kitchen. The house physics rules for our particular unit say we can't travel any faster than the speed of light within our universe. But there's nothing saying that we can't go outside the apartment--into the empty hallway between the universes, where the speed limit would not apply--and get to the kitchen that way. The Bulk--the empty hallway between universes--just represents a region through which we may be able to travel. It fits the concept of hyperspace.
Of course, there are no guarantees that the rules of the Bulk would allow faster-than-light travel. But we do now suspect that there is a realm that has some of the properties that we attribute to hyperspace--outside our own universe, difficult (or impossible) to access, with different rules and limits. For a science fiction writer, taking a plausible but hazy scientific concept and giving it the attributes you need for your story is vastly preferable to just making up something like "hyperspace."
I found this really awesome interview on the background of hyperspace that I thought I would share, it's really fascinating:
