I'd believe the small percent of a percent of the sky we're in for it to be pointing at us is still a large swath of trillons of miles. And 850k years from now

I'd believe the small percent of a percent of the sky we're in for it to be pointing at us is still a large swath of trillons of miles.
And 850k years from now - our galaxy would have moved from it's location anyways. Some other galaxy will probably waltz into it.
- snarf21 4y agoVery interesting. Does this imply (assuming these jets have been occurring for a very very long time) that we'd be able to see the consequences of other jets in other galaxies/planets? Said another way, have we ever observed something that could actually have been "... some other galaxy waltzing into it"?
- Gh0stRAT 4y agoOne of Earth's past mass extinction events is hypothesized to have maybe been caused by a gamma ray burst[0]. I don't know enough to speculate whether it could have been caused by one of these jets instead.
