Maybe form a polar jet and get the whole solar system (Oort cloud excepted, sorry!) boosted out of the plane of the galaxy. It is dangerous here! You never know when a supernova or magnetar quake might sterilize the entire solar system. By the time you know it is coming, it is too late to do anything but flee with minimal baggage.

If you boost into empty space (and not say the Magelanic Clouds or something similar) you are loosing access to a lot of usable mass. Maybe better to do a lot of backups and stay in the galaxy ?

  Magellanic clouds are even more hazardous than where we are. If you bring the solar system along, you have that; I assume you accelerate slowly enough to bring along the Kuiper Belt. It will take a long time before you need to start thinking about dismantling Jupiter. If you solve the p-11B fusion problem (maybe you invent a mirror for x-rays?), you don't need the sun anymore, and may pick up and move operations to another solar system that is already moving off-disc at a good clip. You can bring along rotating cans of bio-stuff if you still use it (or anyway keep it as pets). The new solar system can have a dead-ish star so the planets are frozen and convenient to mine for volatiles.

Why would the jet and the radiation emitted by such objects be limited to the plane of the galaxy? AFAIK their axis, and thus the direction of emission are randomly distributed. Doesn't matter in which direction you are positioned, except for distance. Which would mean the really deep space between galaxies. But then you'd have to watch out for https://en.wikipedia.org/wiki/Seyfert_galaxy https://en.wikipedia.org/wiki/Seyfert_galaxy ies, too! Whose jet's could fry us even more easily, because 'out there', we wouldn't be protected by the pressure of solar/stellar/galactic wind, dust clouds, nebula, which could protect us (if we are lucky).

  There is no possibility of ever getting close to a different galaxy. The best you can do is get away from the thick part of the galaxy we are in, and its hazards. The jet I wrote about is one you induce to emit from a pole of the sun, for thrust. I have no idea what this other jet you mention is.

    That was in response to > ...boosted out of the plane of the galaxy. Which made no sense to me, because to escape the other, naturally occurring cones of radiation, emitting from different sources, only distance would matter. Just rising above the thick part of our galaxy wouldn't be enough IMO. Because it doesn't really matter if you are cought in such a cone, from one side or another, or from above or below. Because they are oriented randomly, according to the rotational axis of the object in question, which isn't aligned to some 'plane' (AFAIK). So the only way to be sure would be a much larger distance from the galactic mess, out into real emptiness. Which would open it's own can of worms. Because real emptiness doesn't protect against larger jets, coming from larger objects, like Seyfert-galaxies in active state. Edit: To further explain my model of thinking about this, while being in the plane of our galaxy, we could be protected by nebulae, dust and gas clouds, depending from where the radiation cone comes. That would be random(luck). And useless against our next nearest neighbours, if they go boom for whichever reason, and there aren't any obstacles between that, and us, which could dampen the radiation a little bit. Going up or down the galactic plane, would add just a little distance, but not enough to be safe from all the possible cones of radiation coming out of the plane. Because from 'in the plane' to above or below it, there are even less obstacles which could dampen the intensity of that. Less 'fog or dust', but still 'in range', thus easier target. But still somehow in the 'galactic bubble', exerting outwards 'pressure', maybe dampening extragalactic outbursts somewhat. I've been referring to https://en.wikipedia.org/wiki/Astrophysical_jet https://en.wikipedia.org/wiki/Astrophysical_jet , not your method of 'leaving the galactic plane'. So using your jet to leave the plane made no sense to me, because it doesn't really protect against the astrophysical jets, and radiation cones emitting from them. :-)
