its all about the laws of physics .\nif there is enough of magnetic and electric field energy to create enogh heat that can produse some protiens then there will be life again and it does not matter how small the galaxy is !\nbut i think even if such a galaxy is present , it must be far from the bigger ones so that it can magntically stay constant (its just what i feel and believe

new research show that galaxies are held together by dark matter which until recently there was little or no evidence of,however i believe the massiveness of the entire universe is actually exerting pressure ever so slightly upon the galaxies and that force is squeezing them upon a tightly wound black hole which appears to be a gravitational force, but i compare it to all the water in a tub pressing itself gently into a whirlpool as it goes down the drain...yes it is gravity pulling it down the drain but if that same whirlpool was in space it would have more similarities to a black hole

It lies just 1,600 light-years from Earth on the way to the center of the Milky Way in the direction of the constellation Sagittarius.\n\nThe black hole, which is associated with a visible star called V 4641, is being called a micro-quasar because it exhibited for a few days in September the brilliant behavior associated with quasars. It sent out tremendous bursts of X-ray radiation and shot out jets of plasma at some 90 percent the speed of light, said Robert Hjellming, of the National Radio Astronomy Observatory.

The realistic answer is no, for several reasons.  \n1)  Our sun is too small to collapse into a blackhole.  Even if it did the planets are too far away to be sucked in.  Just because a star turns into a black hole doesn't mean that its gravity get any stronger.  The planets would just orbit it like normal except that there would be no light coming out of it and also no heat.  \n\n2) Our galaxy spirals around a black hole and we haven't been sucked in yet.  Once again, that is because a black hole is only as strong as the mass it contains.  Instead it just keeps all of the stars in the galaxy orbiting around it.  \n\n3) They only way it is possible is if one of the minor galaxies which orbits our galaxy happened to collide with the Milky Way.  If that were to happen the black hole in that galaxy could pass near enogh to the Earth or our solar system to suck us in.

i've already started packing.  i'm scheduling for 8am tomorrow.   \n\nHonestly I don't think anyone can really answer that.  If you are a person of faith then who knows other than when God decides.  If your not then you rely on all the brilliance of scientits, at their guesses I would guess another millenia before we completely wipe out all resources from the earth.  But until it comes to a complete end you have to be more specific, do you mean, end as in uninhabital and we have to leave it, or it completely is wiped out through some catastrophic event?  in the question of catastrophic event i would say 5 billion years (look to my resource link).\n\nIN RESPONSE TO...\nWOLF:  you claim that the sun will super nova in 9 thousand years due to universe facts.  well you have AMAZING universe facts considering that our sun will NEVER become a super nova.  even if it it where a star that would  super nova it wouldn't dry up our water.  come on, do you know what a super nova is?  if our sun exploded then there would be so much energy released that earth would more than likely be completely devasted to the point of utter inhabitation, oh and dry up our water.

Theoretically yes.  One type of supernova is due to a massive star ending it's life.  The star literally blows itself apart.  You need a star of about 8 times the mass of the sun for this to happen.  As such the sun won't have this form of supernova.\n\nHowever, the sun will end it's life as a white-dwarf.  As such it will drift through the galaxy and cool off for a long long time.  If at some time in the future the "dead" white dwarf sun runs into s sufficient source of mass it may be able to exceed 1.4 solar masses of matterial.\n\nWhen a white dwarf accumilates that much mass it will spontaniously undergo a rapid, and destructive fusion cycle that will blow the white dwarf completely apart.  This event is also a type of supernova.  Since the sun does not have a likely source of this extra mass, this fate is very unlikely, but since white dwarfs last for exceedingly long times it is possible (but unlikely) for this to happen.\n\nIt is an extreamly small chance though.

you should see the nova on blackholes, it was on last week\n\napprently only to much can actually get to the center at a time, and most matter/energy gets bounced around within the event horizon, never to escape, but not actually getting all the way in\n\nand anyway blackhole emit particles of hawking radiation and would eventually expell there mass and kinda evaporate away\n\nand if one black hole had the whole universe in it, sounds prime for  big bang to me

Didn't you see the movie Men in Black?  Our universe is inside a marble being used in a game by aliens.

It depends so much in what you consider to be an object. If a galaxy is one object, then the largest supernova will be only a very small object compared to it.\n\n\nChandra x ray observatory took images on 2003 of two distant massive galaxies that are between the largest objects scientists have found. \n\nhttp://spaceflightnow.com/news/n0305/21construction/

Well, people have been spotting and reporting MACHOs for a long time, simply by how they affect light that passes through them.\n\nI believe that WIMPs, if they exist, would be the source for more of the energy density requirements to keep omega at ~1. MACHOs only exist within galactic halos, and are aggregated. WIMPs, on the other hand, are likely to be evenly distriubuted within and between galaxies, acounting for their rotation and their movements relative to one another. I think the lack of information about WIMPs is simply due to the limits of our technology in being able to detect particles that only respond to gravitational fields and require a lot of energy to make because they are heavy. If a particle does not interact with any force at all except gravity, it is likely to be a long time before we ever prove that it exists.\n\nI also think that the fermionic superpartner to the Higgs boson is a good candidate for the WIMP, and it is likely that the debate on the existence of supersymmetric particles will be put to rest as soon as those giant particle accelerators are built in Europe. I think the one is supposed to be online in 2008.

No, I think it'll take too long for them to join together.  They're generally so far apart that the gravitational pull on each other is very very small.  Besides, the universe is constantly expanding, so instead we'll end up in a position where everything is just cold and the density of matter is very small.  That's just one theory, though.

one of the properties of a neutron star (as far as i can tell) is that the electrons and the protons are so tightly packed that they form in to neutrons. But they are not bound together like they are in the nucleus of an atom.  \n\nThere is actualy a great statmech problem where you are suposed to calulate the radius of a neutron star using only the pauli exclution principle (basicly that fermions have the tendency to repell each other)\n\nat the moment there are two known things that are even denser... a black hole for one, and the neuclus of an atom. \n\nIf there was a free existing small part of a black hole, it would just explode in a matter of moments (~10^-14 sec i think).  as for a neutron star they would also fly appart because for the pauli exclution principle.  But if we have a huge mass of protons and neutron we would have a very very very very heavy atom.  It would attract electrons just like a normal atom.  But it would decay in just moments(problably very violently).   \n\nIt can be made, but it would exist in such small quantity and for so short of a time that it would seemingly have no properites

It will go nova and a star 15+ sm's will go supernova (if I remember correctly)

There are many thoeries to how this process works...we all know that black holes are the decayed from of a supermassive star.  Technically the universe would have to all collapse before it could expand...like a star it has massivle amouts of atomic energy, and non atomic...al matter was inside this small, infinitely dense space.  Then, the big bang appeared and everything expaned.  My personal theory or space time is that there is no limate to space therefore there is no limit in time...there is no beginning or end to either becaus they are related to each other and mush remain at a simimal or equal constant.  Thus everything within time has a finite length.  The events in time will end, but not time itself.  There is a lot to all of these theories.  Anyways the point to this is that there is a center to the universe but not space.  Anything that is a mass has some ammount of gravity...some, though have more energy than others.  This is what makes a black hole.  the things in a black hole are packed into an infinitely small space.  Then hydrogen plasma shoots out of some supermassive blackholes.  this energy still remains a mysterty to me on how it can escape the black hole, almost like the big bang, but more controlled.  there WAS a mass at the center of everything, but how that works still is a mystery.  I think that there were once supersupermassive aters where the center of our calaxy is today.  this explain the expansion of out galaxy and the surrounding stars and such.  So there was once a biis mass that keeps dividing till it smaller.  Sadly at the end of our universe, everything will once again be absorbed.  That last part is my thoery.  But can we survive?  Well I hope I answered you're question thurough enough.  My hands are kinda tired.\n\nBTW...does the stuff I said too confusing or does it work..I'm not exaclty the sharpest when it comes to these things but I'm pretty sure I know what I'm talking about?

Eric Jaffe-Magnetic Thrust: Fields force matter into black holes\n\nLike a child scared to dive into a pool, cosmic matter needs one last push to plunge into a black hole. New observations confirm that magnetic fields provide this final galactic shove. \n\n The observations come from a system in the Milky Way called GRO J1655-40, which consists of a black hole and a normal star. Gas from the star is pulled toward the black hole, where it forms what's called an accretion disk. Angular momentum—the same property that keeps Earth from diving into the sun—keeps the disk revolving around the black hole instead of falling into it. \n\nUnless something knocked them off course, the gases in the disk would continue to circle the black hole forever. "To get matter in toward the black hole, we have to change the orbits in the disk," says study leader Jon Miller of the University of Michigan in Ann Arbor. Until now, scientists weren't sure whether magnetic fields, radiation pressure, or heat alter the orbit and trigger that fall. \n\nUsing NASA's Chandra satellite observatory, Miller's team collected data on X rays emitted from the J1655 system. They found that the X rays came from a wind blowing from the disk, so some force must propel the wind past the black hole's gravitational pull. After simulating the wind on a computer, the researchers conclude that only magnetic fields could create such a force, they report in the June 22 Nature. \n\nThe team had ruled out a wind fueled by heat from the core of the disk or by pressure from radiation blasting out of the disk. A heat-driven wind would have been hotter than the one that the researchers observed, and radiation pressure is too weak to drive that wind. \n\n"Magnetic pressure really was the only viable means remaining," Miller says. \n\nSuch pressure could upset the gas disk's orbit in two ways. The magnetic fields could push the wind outward like a spring, or the force of the spinning disk could fling the wind away from the disk's center. Either disruption of the disk's orbit would cause some matter to spiral downward. \n\nMiller's team appears to prefer the first scenario, says Roger Blandford of Stanford University. Blandford prefers the second, which he describes as an organized magnetic slingshot. "I suspect there are different answers in different types of systems," he says. "But on the face of it, this looks like a big advance observationally." \n\nThough most astrophysicists expected magnetic fields to play a role in black holes, the finding is "very important evidence that what we thought before makes sense," says Avi Loeb of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. "It's the first time there's clear evidence for wind coming off an accretion disk." \n\nThe finding could help astrophysicists understand the complex give-and-take between galaxies and black holes,

It all depends. The controlling factor is the total amount of matter in the universe. As far as has been detected, this is very close to the "tipping point" between continued eternal expansion and a slowdown and eventual stopping and reversing (a contraction). The thing is, we don't know how much "dark matter" there is, and we still don't know definitively if neutrinos have any mass or not. So, at this point in our knowledge you can take your pick. Neither one is attractive. In a n eternally expanding universe, every particle of matter that isn't gravitationally or chemically bound to another will recede from it forever. This would mean that at a far distant time, our galaxy would be all we could detect in the heavens, and since there is only so much matter in our galaxy which can give rise to stars and stars have a finite life, the universe, if we could still exist under those conditions, would be a totally dark, cold p[lace. A contracting universe would be no better. Once expansion stopped and contraction began, the entire universe would be totally bright, and inconceivably hot. Neither sounds like my idea of a nice environment.
