- Yes. I'd like to continue toying with that idea. Maybe the "looking" has to be some novel kind of sensor. Passive sensors barely work, and using active scans immediately announce the presence of the scanner.
Perhaps there's some naturally occurring stuff out in the W direction (possibly a form of dark matter?) The natural hazards are coarsely mapped and difficult to detect.
Another thought… perhaps the energy required to leave the W=0 volume increases greatly at close proximity to a gravity well. So if a hyperspace sub is near a star or a planet, it is forced back to shallow W distances.Oct 5, 2015
- there are certainly lots of interesting lines of speculation.
A star or planet with a W+ coordinate would appear in our xyz universe as a place with gravitational attraction but no object in the center.Oct 5, 2015
- The math for distances is easy, just add a fourth term to the true distance equation.
Distance = sqrt( (x1-x2)^2 + (y1-y2)^2 + (z1-z2)^2 + (w1-w2)^2 )Oct 5, 2015
- In my old 4X space campaign stealth ships (aka submarines) had to anchor to reality with a "periscope" or be lost forever in their own quantum universe. Worked well. Especially since the "periscope" tended to be fairly vulnerable to attacks.
[I prefer the classification by designation used by naval architects for these sorts of designs up until WW2. A battleship is any ship designed to engage with the enemy battleships. A cruiser is designed for independent long range operation (or as part of a squadron in wartime). A destroyer is short for patrol boat destroyer. Of course that later assumption requires the existence of torpedoes capable of being carried by lighter units and which are capable of destroying even the most powerful battleship. Just whatever you do, don't try to add aircraft. ACV carriers fine. Aircraft, no.]Oct 5, 2015

- You might like my pet idea for convenient magical physics FTL - ballooning in hyperspace. As per's idea, there is a W dimension, but without magical hyperspace drive everything falls onto W=0. But the layers aren't fixed with respect to each other, they are sliding past each other at FTL speeds, like fast horizontal winds.
So, the FTL drive works by adjust hyperspace "altitude" up and down to reach an altitude where the "wind" is in the desired direction. Usually, this restricts motion to a wide cone, and but it might only be possible to go in one direction between two systems. Even if it's possible to go in both directions, the speeds may be radically different.
I didn't really think of this scheme as "stealthy", though...not any more "stealthy" than any other FTL propulsion system. A spacecraft operating its hyperspace drive will inevitably have some sort of exhaust...propellant, or waste heat photons, or whatever. These immediately fall into real space, possibly acquiring a lot of thermal kinetic energy in the process. Either way, it leaves a visible trail of evidence.Oct 7, 2015
