Wouldn't the galatic rotation mean the earth will be somewhere far away when the jet travels that far?

[mynegation]

On the flip side that also means that we might flow into a burst travelling through space without any warning (?)

That got me wondering how far we'd move - if my maths is correct then in 850,000 years time our solar system will have travelled 652 light years around the galactic core (230 km/sec * 850,000 years)!

How wide is the beam? (given how far it started) Light-years?

Is it still dangerous at this point? (If its energy is spread over a giant area radius billions light-years)

[suzzer99]

Yes, that and both galaxies careening through space on different trajectories.
