Seems to fit my own impressions I got when I was doing starmaps

The chimney shape is rather obvious due to the thin galactic disc; the
"wind" will by necessity be outwards.

Aren't magsails rather inefficient when used interstellarly?
Personally I have always thought antimatter is the only way to go.

I seriously doubt it has any big effect. The holes indicate past
supernova or blue giant activity, which might be nasty if you are too
close, but since we are happily sailing through a slightly old hole they
are not dangerous in themselves.

Only if all aliens are sending at frequencies likely to be impaired;
this is why so many have listened at the clear frequencies.
