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.

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.

DeeHawk t1_jdv9ly0 wrote

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.)

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

AlexOwlson t1_jduhvo2 wrote

Wouldn't even be possible. The gravitational pull would be stronger when we're closer to it than the sun, and weaker when we're on the far side of the sun. The earth spends half a year with it's center of mass closer to the black hole than the center of mass is to the black hole and half a year further.

Meaning if it were able to pull the earth at all, it would necessarily pull us further from the sun, not closer. The same is true for all objects outside the earth's orbit around the sun.

2

Alphaesk t1_jduhz3c wrote

Thanks for the explanation, so mass of the object has no role on the pull and sun and earth gets pulled the same?

2

AlexOwlson t1_jduiez6 wrote

Yeah both would get pulled. Mass ratio between the objects has effect, but in this case both the sun's and earth's mass would be negligible compared to the black hole, so we can assume the black hole is not pulled back into an orbit around the sun-earth system.

Distance is a more important metric, as the effect is divided by the distance squared. So the further away two objects are, the less they pull each other.

Now assuming both earth and sun gets pulled what would happen is the earth's orbit would become more and more elliptical over time and the average radius would also grow over time, moving us on average further away from the sun. At the closest extreme of the elliptical path it might be possible we could pass closer to the sun than before the black hole starting pulling, but this requires a bit more mathematics than I'm willing to do as I'm supposed to be working atm.

Long story short: only the sun itself can pull us closer to the sun, but as long as we are orbiting through approximate vacuum that's not gonna happen. With friction though, say if the sun's orbit passed through a gas cloud that might happen, but we'd probably have much more serious problems before crashing into the sun if that ever happened.

Devertized t1_jduz6t8 wrote

Wouldnt it be possible, in theory, to shift the earth trajectory to a point where the sun's gravitational field would pull us closer ever so slightly until collison?

1

AlexOwlson t1_jdvpc5c wrote

Even in theory it would be difficult. With gravity alone I only see it would be possible if either there's a massive object that magically could turn on and off it's gravitational pull in sync with the earth's orbit around the sun, or if an object actually passes through the solar system just past the sun and at that moment is lucky enough to dart the earth into the sun (which would be one extreme unlikely hole-in-one).

I think there's a lot of thinking that's a bit misunderstood here, but the entire universe except for mercury and venus is actually pulling the earth away from it's orbit around the sun. In our local solar system, the sun is massive enough that's it's only a few centimeters per year that we're creeping away, but there's no way anything outside our orbit could pull us into the sun, except maybe for some bizarre theoretical phenomena, assuming gravitation is the only external force (a collision, for instance, is a completely different story!).

If a force was strong enough to do that, it would pull the sun out of that collision course as well and we'd just end up with an even more extreme orbit around our yellow friend, if we would even be able to maintain that as we accelerated towards whatever is creating the massive pull.

Depth_Metal t1_jdto0ac wrote

Well first of all that's from the New York Post. Second my understanding is that the actual pull of Black Holes (on a relative galactic scale) not that great. Not great enough to affect us from another galaxy. So I doubt we are in a position to be consumed by it. Perhaps the x rays being sent out might affect us? But we only know the position and facing of the black hole from 657 million years ago. It's facing might have further changed in the meantime

yukimi-sashimi t1_jdujo4i wrote

There is nothing special about the gravitational pull of a black hole. It has pull according to its mass, just like every other object. If you have a black hole that is the mass of the earth, then about 4000 miles away from it, you'll feel a 1G pull.

If the sun was suddenly replaced by a black hole, we'd continue to orbit. We just wouldn't get any sunlight, and of course that would be an extinction event, but that's beside the point

Maybe a nice, big Gamma blast is headed our way? It's speculated that it has happened to Earth before, and wiped out %90 of life on land and in the sea. Mankind better start getting serious about reducing the single-point-of-failure issue when it comes to our survival. We *have* to get off this rock and start moving up on the Kardashev scale. Especially if we are concerned about survival as a species. Not sure we deserve it but....Deserves got nothing to do with it.

The rest of the entire galaxy is also (mostly) utterly insignificant because of how far away it is that it doesn’t matter. In our little corner of our solar system we are pretty damn significant. Just because we aren’t a tier 5 turbochad galaxy eater civilisation doesn’t mean we don’t matter.

First of all this thing sits a whopping 657 MILLION Light years away, not miles LIGHT YEARS blazars are nothing unique. Closest One sits 400 million light away. While we can see their jets, the matter itself only reaches hundreds or thousands of light-years. Even if one happened in Sagittarius A* (can't for at least 5 billion years) the closest SMBH to us. We wouldn't die. What's so unique about this specific blazar is the fact it changed direction in the first place, nothing to do with the fact it's a blazar

Not really true for regular, bog standard black holes (accretion disk and jets are non symmetric).

James20k t1_jdt9uql wrote

A black hole has a spin, and spins about an axis which means that you can define a direction that it is pointing fairly straightforwardly

Black holes also aren't point like objects, the interior/singularity is completely divorced from the exterior of the black hole - they are a property of spacetime itself, not an effect that arises from the singularity

Astrophysical black holes formed from stellar collapse also don't have a singularity as viewed from an external observer

Well, there is something to your explanation. Axis is a property of direction. Yes, black holes do occupy space so they are not point like. I was wrong.

As Earth was pulled down the gravity well of this dead star, our relative time would become increasingly faster compared to the rest of the universe. From our vantage point the time of the rest of the universe would slow down and all but stop, while we would experience millions of years of time passing relative to the rest of space. It would be like that episode of <3, Death, & Robots with the freezer civilization. We'd probably come up with FTL travel before our people could be turned into cosmic spaghetti, and be able to escape the Black Hole's event horizon.

To us time would not change. From inside looking out, everything would be going insanely fast. Outside looking in, it would look like time stopped.
