In sci-fi media, hyperspace visuals often feature elongated, glowing streaks of light—typically white-yellow—that stretch across a dark backdrop, creating a tunnel-like effect. These radiant beams, resembling stretched stars or particles, convey rapid movement or a dimensional shift, as seen in Star Wars hyperspace jumps where light rays explode outward.
These are true. I found one below where you can see it appearing as a result of particles splitting.
I assume the atom split liberates so much energy the void you see, is the space where you can travel to as a new dimension, to create.
The dimensional grid we see, does not seem to have any shape as our vision is limited.
However, the donought shape below is the whole version. I have not seen it entirely.
However, the best advice given to me is to focus on the centre. It makes sense, otherwise you cannot find the exit.
What happens from the centre? No clue, I suppose exit is way up ;)
