Hyperspace

Hyperspace is seemingly an alternate non-euclidean dimension that Reverie appears to enter whilst jumping long distances in a High Energy Warp State. Entrance to this dimension seems to be a consequence of the strange warping of spacetime around an object. It warps so much that the object is bent out of its current spacetime continuum, suddenly ceasing to exist in that dimension.

Entrance
As Reverie begins to inject light plasma into the warp mechanisms, the space around the ship becomes distorted as spacetime is becoming extremely bent. Streaks of light shoot past the ship from out of nowhere, and as the warp drive reaches its highest speed, a jump beep rings and announces the beginning of the jump. As this happens, space around the ship visibly folds forwards, away from the viewport, then slingshots backwards, making the background stars disappear. There is no sudden acceleration, as the ship wasn't actually accelerating when it jumped.

Within Hyperspace
The dimension appears completely void of any matter besides from a few strange passing lights. When the ship grows nearer to its destination, a light will appear in front of the ship a large distance away. This is confirmed to be the color of the targeted stellar object's blackbody radiation curve. The light becomes brighter as the ship approaches, illuminating a mist in the color similar to it. As the destination is reached, a bubble appears for a split second before snapping normal space back around the ship, returning Reverie to the normal dimension, at its intended destination.

There are random lights that the crew observes whilst travelling through Hyperspace. They travel in any direction but mostly opposite the direction of travel. Bryony also notes a strange golden haze that only appears to the left of Reverie that does not move. Upon reentering the normal dimension, the golden haze is replaced with the faint disk of the milky way, providing more evidence that the two dimensions are linked.

Relation to the Normal Dimension
Background tests that were run by ship equipment found, as well as on accident by the crew of Reverie, that either time passes longer in Hyperspace than in the normal dimension, or the hyperspace conduit does not follow euclidean geometry and its apparent physical length has no relation to distance in the normal dimension. An example would be jumping from Sol to Alpha Centauri A. A total of five minutes and thirty-one seconds passed the entire time Reverie was in Hyperspace, but only some seventeen seconds passed in Earth Time from the time Reverie disappeared from Sol and turned up at Alpha Centauri A. This brought up the question of if Hyperspace and our Universe are related at all.

It was found in a follow up test done on plant life carried on the ship, and the crew of Reverie, that they did not biologically age while in Hyperspace. The laws of physics within the dimension itself still appeared to follow the same or extremely similar laws within our Universe, as the speed of light was still observed to be 299,792,458 meters per second and heat transfer of The warp drive was consistent with normal dimensional readings.

Distance Traveled & Trajectory
It was proven on accident that physical distance is in some way related to the normal dimension in relation to Hyperspace. Reverie dropped out of Hyperspace before its intended target was reached, resulting in them returning to the normal dimension a considerable distance away from the Alpha Centauri system. It wasn't proven but assumed that Hyperspace creates a straight line trajectory that the ship would follow in the normal dimension from the jumping point to the destination.

Trivia

 * The golden haze Bryony sees in Hyperspace is in fact a representation of the Milky Way. Although nobody noticed, there is a fuzzy haze within hyperspace where the Andromeda Galaxy is.
 * Hyperspace can provide residence. If a person were to exit the warp bubble moving a spaceship through hyperspace, they would be stranded.
 * The light of the star appearing in the distance in Hyperspace is the actual star, as while the ship is travelling in Hyperspace, in the normal dimension, spacetime is slowly folding into itself, creating something like but not resembling a wormhole, allowing photons to pass through, as they are a massless particle.
