That was one of my main concerns and the only solution I can immediately come
up with is the Multiple jump scenario. Trouble is, the more jumps you make,
the more expensive the journey. (Unless the jump itself lowers cost by some
sort of space/time bending, straw clutching for answers)
There is a way that this could happen. If the journey in our universe is
impossible and therefore infite cost, any route would be cheaper. regardless
of how many jumps are needed to get to the components and back.
If the parallel universes are layed one next to the other, then this causes
problems because the particle would most likely get to a universe where a
simple straight connector exists rather than a component like a transistor.
however if the universes are branched so that the particle can take any
number of routes, then some can make it to the desired components.
My brain hurts.
