Will the universe of galaxies end up in a black hole?

Question

There is a black hole in the centre of our galaxy, sucking in matter.
If we are typical and there is a black hole some where in every galaxy, then surely that is where all matter will go eventually. Agree?

And then will anything come out of the other end of the BH to start the formation of another primeaval atom and another cycle?

Answer 1

Yes........more or less. A Black hole is a small view of what the universe as a whole will be like billions of years from now.

Answer 2

Nope, not all matter will go into a single black hole, its simple physics using opposing forces. An object exists between the sun and the Earth. The laws of physics state that at some point between the Sun and Earth, the object will neither accelerate towards the sun or Earth because the force being produced by the two masses cancel each other out. The same principle will work here, seeing as the blackwhole isn't the only thing generating force in our galaxy, we will not be sucked into it.

As for your second question, your assuming there's an end to the blackhole. Its better to believe that in the center of the black whole is an infinitly dense, contionously spinning "ball" of matter. This is most commonly accepted because the acceleration due to such a highly spinning small object could be the cause for a blackhole's incredible gravity.

Answer 3

The second part of your question is an interesting tack to take when you speculate about singularities. To answer your first part, black holes don't "suck." If something crosses the event horizon of a black hole, yes, then they suck. Otherwise, things just orbit around it if they are close enough to be in its gravitational well. Billions of years can go by and a black hole may not "feed." Then you see nothing. But when some star wanders too close, then you can detect the tell-tale accrection disk as matter spirals into the BH and is accelerated to near light speed as it is drawn "down the drain." So, I don't think a galaxy's black hole(s) will consume it. It could be though that the exapansion of space will distance everything from everything else, and in a few 100 trillion years, it's going to get pretty dark around here.

Answer 4

Universe is expanding. Every galaxy is moving away from each other. It will not be sucked in by the blackhole in the center of the universe.

But, my doubt similar to what you have is, when a black hole sucks stars or other galaxies in it, its diameter of gravitational attraction increases and sucks those stars and galaxies that fall with in that new diameter.

This will come to an equilibrium only when there is no stars or galaxies that fall within the gravitational attraction of the BH.

If the expanding universe is faster than the expansion of the diameter of the gravitational attraction of black hole, we are safe.

Since the universe is expanding, we would reach far away from the attraction distance from the BH.

Answer 5

There IS a black hole in the milkyway.
There is 1 black hole per galaxy (this seems to be the standard for all galaxy formations)
Not all blackholes are active (consuming matter)
Not all matter is lost to a blackhole.
The rest is in the form of dark matter (about 3/4 the entire matter in the universe).

There have been white hole theories but we are able to 'see' blackholes but whiteholes are no where to be seen.
white holes are believed to be the otherside of a blackhole (like a wormhole) dumping matter into the surrounding area. We should have been able to see massive energy bursts from these but the only source of high energy is from 2 massive objects (a few hundred times our sun) collapsing into each other giving off gamma bursts...but thats another answer to another question.

Answer 6

It is entirely possible that all matter in our Milky Way Galaxy could at some point in the distant future be sucked into the black hole at the centre of out galaxy.

Answer 7

up to a certain point. even though a black hole sucks in stuff, there is a boundary just outside the BH that is filled w/ the BH's gravitational energy but not to suck anything in. since energy and mass (matter) are the same accg. to E=mc2, particles can be created here, in matter-antimatter pairs. if one particle gets sucked in,the other will escape. since the particle escapes, there is less energy in the BH, therefore less mass. in a few trillion years the rate of particles getting out by this process is larger than the rate of the BH sucking in stuff that it will explode. as it does matter will re-scatter through the universe.

Answer 8

No. If you accept the Big Bang Theory, and most folks do, then the universe is expanding because all matter is being expelled away from the point of the initial explosion. However this expansion will end one day... probably on a Saturday. (Not in our lifetimes though... don't worry). When that happens, gravitational attractions will slowly draw all matter in the universe back together again, contracting the universe and multiplying the gravitational attraction between large masses until it all collects together again and another Big Bang happens... again... for, what is it now?... the 27th time?... or is the universe on its 28th Big Bang?... I forget. The point is, it keeps happening over and over again. Interesting, huh?

Answer 9

I read some years ago in "Scientific American" that certain astronomical observers have made measurements showing that the galaxies are moving apart and outward at such a fast rate that it is faster than the escape velocity from the universe's gravitational pull, so it is no longer considered very likely that all of the galaxies will fall back into the center again. But, if there are experts who disagree, I don't have the knowledge or the wits to argue with them!

Their conclusion is reliable to the extent that they have accurately measured the amount of matter hence the strength of over-all gravitational attraction in the universe.

The fall-out from this universe, in case it did happen, as you say, might pop out into another universe, and then again it might not. But, friend. If you fall into a black hole, I think it is going to grind you up to flinderjigs, which, according to some physicists specializing in sub-atomic particles, are even smaller than smithereens. These particles are so small that mesons and pions can't even see them, and they are so insignificant that if the bigger chunks of the atom could see them they wouldn't speak to them!

Egghead astronomers, snurling up their noses at the flinderjig theory! Just because the scientists that came up with it, my cousins in the Cumberland Mountains of Kentucky and West Virginia, thought of it over a bottle 15 minutes ago, and called me and told me about it. Their theory, your theory, and my theory on something that nobody knows anything about in the first place is as good as anybody's.

But not to worry: I read somewhere, I think in "Asimov's Guide to Physics", that, if the theory of a black hole in the center of our galaxy is true, folks like us, way out on the outer arms of the galaxy, are too far away to be captured in its tidal pull.

Of course, if you go and start poking your toes into the center of the galaxy, don't be surprised if you get your foot caught! Take a sidekick with you when you go, Kemosabi: Tonto might have to cut your foot off to rescue you. Try getting it out with a standard shoe horn, and the black hole'll just slurp it up along with your toenail fungus.

Answer 10

I am glad that you asked this question because it is never brought up on any T.V. shows about astronomy and it should be.I personally agree that all galaxies will become black holes and one day they will all be drawn together to become one gigantic, enormous humongous immense black hole and then this alcohol will explode creating the universe all over again It will be another "Big Bang". I guess what i am saying is i believe in an oscillating universe and i believe that is how it will occur.

Answer 11

There are black holes located in the center of every galaxy we've studied so far. Whats interesting is that Black Holes evaporate,,,,go look that up for the answer you're seeking
