Black hole confusion!?

Question

I looked at an article once, saying that people believed the center of the milky way was a supermassive black hole. So...would it not be unreasonable to say that maybe our galaxy or even the universe could be sucked in and formed into a singularity, and then it could be expelled into a parallel universe? or even be the be the beginning of another big bang? But then, if there are more than one black hole, which singularity is being expelled first? If they are expelled at all...Wondering if anyone could shed some light on this...its confusing me as I type it.

Answer 1

whoa. clam down
yes. almost each galaxy we've looked at including our own has at least one black hole (or imploding star) keeping it together.

slowly, one by one they suck up stars. but WE don't have to worry about it.(for now) we're on the outer edge of our galaxy.

it would take billions of billions of billions of years for us to even come close to being worried about it.

NO, we (the universe) won't be sucked into a singularity as a whole. since billions of galaxies have them and we haven't been sucked in yet, shows the chances are pretty good we (majority of the galaxies) will survive

But, Andromeda galaxy is on its way toward us. We have a better chance of being thrown out of orbit (OUT of our galaxy) from the collision than we do of being sucked in.

even if we do get sucked in, it opens the "possibility" of our matter feeding a new big bang in a different mutliverse. now that's the way to go.

Answer 2

Scientists know far less than what they don't know about the Cosmos. However there is no evidence or theory that says black holes are destined to devour the whole universe. Things that go near a black hole end up like a bug on a windshield. The word hole in this case is misleading. It is not a hole in the sense of what we know here on Earth like a hole in the ground or a drain in the sink with sides and so forth.

A black hole is a sphere like our Earth or the Sun. Like the Sun, a black hole also is a star who's gravity is so strong that light cannot escape it's surface and shine out into space.

If you could get close enough to a black hole you would see what would appear to be a dark circle . This is how it came to be called a black hole. Compared to and among all the bright stars in the heavens these strange phenomenon are like a dark hole in space.

Knowing this now you can see that anything that gets near a black hole does not go anywhere but to certain destruction.
It is no doorway to a parallel universe. A black hole does not reach a point where it would go supernova like a star does. It would only grow larger. There is no evidence that the black hole at the center is "eating" the Milky Way galaxy.

Answer 3

The mass of the singularity causes the singularity to undergo Big Bang. But that takes tremendous mass. A singularity that is smaller, say the singularity in the middle of our galaxy that will one day absorb our galaxy into it is too small for the Big bang to happen. It will slowly evaporate under Stephen Hawkings hypothesis of evaporating singularities. The smaller singularities within our Universe are quantum singularities compared to the Big Bang singularity that created our Universe which, means that tremendous energy is needed to overcome the gravity the singularity's mass generates in space to cause the Big Bang. Even though singularities absorb mass around it, it would take all the galaxies within our Universe to create a big band in an area of our Universe. From this we can say the singularities evaporate from Hawking radiation. At the Big Bang singularity all fundamental forces of physics are applied but the the fundamental forces of physics are causing the mass to be at a very high energy state. This energy state causes the mass to undergo Big Bang. We have billions of years before our galaxy is sucked within the black hole but by then the Earth won't exist and we will be playing Yahtzee in heaven with Jesus and Buddha as the Universe starts contracting into the massive singularity to undergo a Big Bang once more.

Answer 4

Nothing can be sucked into a black hole unless it passes through the event horizon. At a distance, a black hole has the same gravitational pull as another object (say, a star) of the same mass. So we just orbit it, not get sucked in.
But if each black hole is linked to another universe, I suppose there could be an infinite number of universes. Maybe each black hole spawns a new universe. It's a lot to think about.

Answer 5

Pulsars, Black Holes & Singularity
General relativity predicted the formation of black holes from neutron stars. (Neutron stars are remnants of exploded stars, see Iron below). As more matter falls into a neutron star its mass increases; and as its mass increases its gravity increases. A point will be reached where gravity would have grown so much that not even light could escape, thus a black hole forms.

Most neutron stars discovered today are in the form of radio pulsars. They are called radio pulsars because they emit radio waves; we can simply connect a radio telescope to a loud speaker and hear a pulsar. Pulsars sound like someone persistently knocking. Click here and listen to a slow knocking pulsar. Click here and listen to a fast knocking pulsar.

So in short, we can hear a pulsar knock; and if matter continues to fall into this pulsar a black hole will eventually form. Moslems say that this is what Allah says. The Quran describes a star by "The one who knocks" and says that it is "The one who makes a hole".

[Quran 86.1-3] And the heaven and the "Knocker" (Tarek in Arabic) 2 How could you know about the "Knocker"? 3 The piercing star (Thakeb in Arabic).

The Arabic word "Thukb" means hole; "Thakeb" means the one who makes the hole. The Quran is describing a knocking star that makes a hole.

At the center of this black hole (collapsed star) lies a location where gravity has gone so mad that space and time become indistinguishable. Technically this is a location where spacetime becomes singular (hence the name singularity). However singular (Ahad in Arabic) is one of God's 99 names. In the Quran God swears by the location of stars which turned out to be His own name:

[Quran 56.75-77] I swear by the location of stars, 76 it is a great swear if you knew, 77 it is a noble Quran...

Here God swears not by the stars but rather by their location (mawakeh in Arabic). Today we know that this location is singular, that is its description carries God's own name: "Ahad".

Moslems ask how coqld an illiterate man who lived 1400 years ago have figured out Pulsars, Black Holes and Singularity?
[Quran 26.2-6] These are the verses of a clarifying Book. 3 You might be frustrated that they don't believe; 4 If We wish, We hand down from the heaven a sign (proof); their necks to it remain subdued. 5 And every new revelation they were given from The Most Gracious [Allah] they dismissed. 6 They disbelieved (the Quran), so they will receive the news of what they have been mocking.

Answer 6

Black holes are not some galactic vacuum cleaners that go around sucking things up. They are not even holes. They are bodies of mass and you can orbit one just like you can orbit a star or a planet. It is only when you get really close that relativistic effects, such as radiation of gravity waves, can come into effect. You then lose energy and fall into it. But you´re still not being "sucked in". Out here we are safely orbiting the center of the galaxy just like earth is safely orbiting the center of the solarsystem. Aka the sun.

Answer 7

Yes. That's why astrophysocists are trying to measure the material in our universe. There can be two answers to the fate of the universe. One of those is called the great crunch in which everything in the universe gets sucked back into a singularity to perhaps create another big bang. The other answer is the universe will expand forever and die.

Answer 8

1) Yes
2) Maybe but not likely

Hawking says anti-particles could evaporate a black hole after a period of time.

Of course I'm not a Hawking's fan

Eventually all matter would get suck into to form a small singualrity and that would eventually get sucked in by other larger singularities until a huge singulairity is formed that is so massive it causes fusion and bang.

That's the general theory.

Answer 9

If a black hole could exist,it would eventually suck up all the matter in the universe and sit for eternity doing nothing.

Answer 10

whilst debris escape the black hollow a small volume of its potential/mass is lost(mass and potential are correct via Einstein's equation E = mc²). Hawking radiation is emitted (not created) via black holes. via this technique, the black hollow loses mass, and, to an outdoors observer, it may look that the black hollow has merely obtain detrimental potential mutually as emitting a particle.
