Tldr a jet of matter black holes shoot out is aimed in our direction. nothing to worry about at such huge distances.

Won't have to worry for about half a billion years anyway.

Maybe we're in the path of a wormhole, and the Galactic Hyperspace Planning Council will give us notice of the intergalactic highway construction project when the Vogon Constructor fleet arrives for our demolition.

Don't act surprised, the plans have been on display for all to read for years.

fr fr, on display in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying 'Beware of the Leopard.”

As long as we are relocated to another class M planet I'll be happy. 🤣

That depends, sometimes the right wing of those planets don't want immigrants, cuz we going to take their jerbs.

But their leaders are already on the spaceship

I doubt it, knowing the GHPC they'll either go along with the plans just to spite the neighbors or they'll completely forget about the project. Part of me feels bad for the poor saps :(

Well X-rays travel at the speed of light so if we can see it pointing at us that means the x-rays would be reaching us now if they haven't diminished.

Except that it could be a year away and we wouldn't know it until it got here.

We can detect bursts of radiation from stellar objects, sometimes with millions of years advance.

No, we detect the remnants of these bursts that happened millions of years ago that are just now reaching us

What do you mean "millions of years advance"? We usually see things millions of years after they happen, and never before

Meant to say away, no idea why I typed advance.

Must set an alarm to get the washing in, just in case. How many minutes is that?

I mean, a GRB would wipe us all out… but it’ll take some time to get here thankfully… but knowing this decade I’m optimistic it’ll happen this year.

If you're looking directly into the eye of the black hole now, it means that was the position 657 million years ago. Gamma-ray speed is the same as visible light, which mean they arrive at the same time.

However, GRB's spread out over 2°-20°, severely reducing its effect over distance.

Which means it has to be pretty close to do any damage. (It would have to be in our part of the Milkyway.)

Doesn’t the fact that we saw it mean that I’d we had anything to worry about, it would be too late?

The ozone layer would be the first major crisis following a gamma-ray burst, and that happens at roughly 3000 light years.

So we have a safety factor of x219000
