    In retrospect that would have been far better for runtime, my dist function ended up being a tad expensive.

    I substituted the rows/columns, with multiplication by the expansion rate if they were all numbers. And then for each galaxy pair do a running sum by going “down” the “right” and adding the distance for each row and column crossed.

    transpose is nice to have in that approach.
