Understand that the wormhole equation is a result of a bi-tensor field operation within the bounds of a dual-simultaneous cosmological constants. Within the bounds of a single light-second, it works, but the wormholes you can make at maximal distances will get smaller on either the input or output end. So don't go thinking you can go crossing the galaxy with what I know; at worst, you'll spaghettify yourself.
I suspect that there might be three cosmological constants operating in this universe at this time; based on the half-remembered bullshit physics I created or discovered in a state of madness, I think that means the universe might be sandwiched between at least three others. If not for the clouds, I might have tried some astronomy while trying to figure out how to get into the big blue tower.
