Jump travel around corners?

Hi all.

Do jump drives only go in straight lines, or can they bend? For example, could a jump-2 drive go "Northeast" one hex, then "North" one hex to reach a planet there?
 
Strictly an IMTU answer ...
jump drives travel in an alternate dimension so nothing in this universe impacts them except at the endpoints
... so there is no need to bend
... IMTU you could jump 6 parsecs along a main, passing through 5 intervening star systems, to arrive in the 6th hex ... only objects in the initial and final hex matter.
 
Straight lines only.
Whether that matters or not depends upon ones interpretations; in Marc's personal TU, yes, it does. (I spent an hour doing some math for Marc this morning, showing that there really isn't enough impact potential to matter until one gets to leap drives)

Same here - J-space is at right angles to all 3 dimensions IMTU.

I explained it to my players with a variant of that old "sheet with a ball rolling on it" example used to explain curved space/time. In J-space, you bounce up off the sheet and land somewhere else. How high you bounce depends on your jump number, and bouncing off of or landing on a part of the sheet that's heavily curved makes things dangerous to impossible.
 
Even ignoring the trans-dimensional effects of jumpspace, if you consider that:

a) every system doesn't necessarily sit dead center in its one parsec radius bubble, and

b) the starmaps are merely 2D representations of 3D space*, and worlds are therefore not necessarily on the same Z-axis​

the likelihood of running into star B while traveling from A to C is extremely rare.

* This is my interpretation, anyway; not sure if it's official or not.
 
Straight lines on the map......



........of course whether the traditional hex navigation map bears any resemblance to real space is another story.

HOWEVER ...

Do not interpret any of this that you cannot Jump 2 to a hex that is one hex diagonally and one hex up. The 2 hex limit (for jump 2) is a range ... so you can jump to any point within 2 inches if your map has 1 inch hexes.

The straight line is not restricted to passing through the center of every hex along the way.

Agreed - I didn't understand that the OP was wondering if it was ok to jump to a hex that isn't in one of the 6 cardinal hexmap directions. A Jump-X drive can jump to any hex that is X hexes or fewer away, counted the usual way. I can't imagine it being any other way, either fictionally or from a gamesmanship perspective.

Yes, you just count the number of hexes.

On the other question, what happens in jump space when a ship passes over or near another system - imtu the navigators are the jump space pilots and they are on duty at those times to glide round any potential hazards - maybe with a little turbulence.
 
Thank you. I have wondered about this question every time I have come across traveller, beginning with some kind of box set I bought (and lost) almost 30 years ago.
