Are we screwed? Any one with advanced knowledge off physic will it impact us?

ASADENA, CALIF. — The most massive black hole yet weighed lurks at the heart of the relatively nearby giant galaxy M87.
The supermassive black hole is two to three times heftier than previously thought, a new model showed, weighing in at a whopping 6.4 billion times the mass of the sun. The new measure suggests that other black holes in nearby large galaxies could also be much heftier than current measurements suggest, and it could help astronomers solve a longstanding puzzle about galaxy development.
"We did not expect it at all," said team member Karl Gebhardt of the University of Texas at Austin.
The discovery was announced here today at the 214th meeting of the American Astronomical Society.
Game changer
The finding "is important for how black holes relate to galaxies," said team member Jens Thomas of the Max Planck Institute for Extraterrestrial Physics in Germany. "If you change the mass of the black hole, you change how the black hole relates to the galaxy."
Because of this relationship, the revised mass could impact astronomers' theories of how galaxies grow and form.
Higher black hole masses could also solve a paradox of the masses of faraway, developing galaxies called quasars. These mysterious denizens of the early universe are very bright, developing galaxies with black holes surrounded by gas and dust, all rife with star formation. Quasars are colossal, around 10 billion solar masses, "but in local galaxies, we never saw black holes that massive, not nearly," Gebhardt said.
"The suspicion was before that the quasar masses were wrong," he said. But "if we increase the mass of M87 two or three times, the problem almost goes away."
Why M87 matters
M87 is 50 million light-years away. Nearly three decades ago, it was one of the first galaxies suggested to harbor a central black hole. Now astronomers think that most large galaxies, including our own Milky Way, have supermassive black holes at their centers.
M87 also has an active jet shooting light out of the galaxy's core, created where matter swirls closer to the black hole and approaches the speed of light, then combines with tremendous magnetic fields. The spat-out material helps astronomers understand how black holes attract and gobble up matter, a sloppy process in which all is not consumed.
These factors make M87 "the anchor for supermassive black hole studies," Gebhardt said.
While the new mass of M87 is based on a model, recent observations from the Gemini North Telescope in Hawaii and the European Southern Observatory's Very Large Telescope in Chile support the model findings.
The study of M87's mass will also be detailed later this summer in the journal Astrophysical Journal.

yah, I herd about this the other day.  my friend was telling me about how it has strange aspects, and it "ate" another black hole.

Did they say how long it will take to impact us in a we can detect?

posted on June 9th, 2009, 2:24 am

If I remember correctly, I don't believe it will ever impact us Ewm: M87 is moving away from us (like most non local cluster objects). The only galaxy you should fear is Andromeda... which is set to collide with us in 50million years depending on what paper you read ).

I not read much when it come to paper thats one of the resigns I posted this to make sheer I was getting correct info.

It was unseating to say the lest to here we have a galaxy crusher next door.

Back to fretting over global warming.

What is this Andromeda you seek of? And should I buy a bunker and stock up on weapons?

Technically, What we see is light that is thousands of Light years away, so really if it was gonna hit us It already would have.  In fact it might have already done so...

Well, Andromeda is another galaxy (M31) which happens to be set for a collision course with us in a lOOOONg time. It is 2.1 million years distant. I doubt we'd personally even notice the effects of the "collision" (which is more a melding and a ripping off of the rims of the galaxies) if some human derived species was still around in that time period (except for a great many more stars appearing in the sky).

Since M87 is 50 million light years away, that light took at minimum 50 million years to get here... but regardless, there is no way the galaxy could already have crashed into ours (assuming incorrectly that it was heading in our direction) because galaxies do not move that fast and because the calculation of distance is not based on where the light from the object was it is based on where the object should be now by calculating tragectory etc. Thinking about such large distances is a bit confusing when trying to figure out where things are in the Universe. For instance, the light from our sun may take 8 minutes to get to us, but we still know that it is 0.6 million km from Earth.

yah, I herd about that too.  They find these things all the time, but they are never quiet sure about time.

Sorry, I'm confused, could you clarify those two statements please?

I herd about the collision course galaxy, and they find stuff like stars exploding, galaxys colliding, but they are never sure about the "when"

posted on June 9th, 2009, 5:23 pm

Actually, "the when" is pretty well understood (it better be: we know within a few seconds as to when the Big Bang occured--one of the most founded "whens" in science). It's the physics of how and why (and what mass) that is more difficult.

Alright, I can't help myself.  We can't prove the Big bang, or for that matter when it happened, or what would have caused it.

OK, Never mind, this thread is no place for this. Everyone is entitled to their own opinion, and I wont go into this arguement.  It will only cause problems.

Show me the paper. This is probably if not THE, one of the most founded events in physics. You would be better of saying that your computer screen doesn't exist (ironically, if you said the Big Bang didn't happen, saying the screen doesn't exist is reasonable because of the physics involved...). As for what caused it, I agree, it can't be proven yet what would cause it, though there are an abundance of hypotheses about this...

All I mean is that it isn't the only Idea about haw our universe was crated.  This is something that we will NEVER know for certain. 

Oh, and Laughing in the face of someone with an opinion dies not make you right in the slightest.  Verry mature Dom,  Very mature.

But because you insist, I will ask you a question.  Why do some galaxys spin backwards. And Why (As you your self stated) are Galaxys Colliding, if they were as you also say thrown into existence by one explosion.  According to psychics they would forever be flying apart.

For one thing, it is no more an opinion than saying the theory of gravity is an opinion. If anything, your statement was insulting at best, because you just implied that the fields of astrophysics and physics are a joke. Likewise, saying "Never" is unaceptable. How can you say never if you haven't tried?

Backwards in relation to what? There is no forwards or backwards, so what are you even stating? In regards to galaxies colliding, that is local cluster: gravitation occurs within local clusters, but ultimately all bodies that are not local are moving apart at an accelerating rate. I believe that you have an incomplete knowledge when you stated these suposed inconsistencies, because "according to physics", these events are quite easily explained.
