Hawking Gracefully, Formally Loses Black Hole Bet

Liora writes "Today at the 17th International Conference on General Relativity and Gravitation in Dublin, Cambridge University professor Stephen Hawking said in his talk titled The Information Paradox for Black Holes that he was wrong about the formation of an event horizon in a black hole, and that matter is not destroyed in a way defying subatomic theory, as he had previously believed. According to the talk's short, "the way the information gets out seems to be that a true event horizon never forms, just an apparent horizon." A New York Times story and a Wired story are available, both apparently based on Reuters information." (This is the formal announcement promised last week.)

      Actually, doing this leads to the NYT having a smaller database, including one entry for all users that share the login. I think the site is a good idea, but its probably doing them a favor, by letting many users who almost never view their site use a single logend. This is better (for them) than a database full of people that visit the site every 6-12 months. But it is probably not really sticking it to them.

      The kind of webmaster I am? lol. We only get about 6 to 8 million hits a year, so its a moderate traffic system, but the same truths hold. Then again, most sites are less than 1 mil a year.

      The data saved per registered visitor is far greater than you state, usually 50x larger. In our case (albeit, atypical) its typically 500k which is 500 TIMES larger than you state. Plus you have to actually *do something* to that data, it doesn't just sit there passively. Users that login in and view one time just creates dead weight in the database, which is why many sites that purge users that have not logged in after a year. If you don't purge, after 2 or 3 years, the vast majority of your database is invalid entries, which makes maintenance and space many times more space and CPU time than is needed.

      And they still get their 1c if you are using a shared login, they don't loose any money, since it is still a "targeted ad", so they get paid the same, regardless. The ad is just not as targeted as the advertisers would like. Sorry, but the arguement just doesn't hold water.

Once any mass or energy comes within the event horizon it is immediately absorbed to the mass at the center point. Initially no energy was thought to escape. Eventually there was Hawking radiation but no real spectral radiation.

      Now a black hole is no longer a singularity in a function but is an asymptote. There is no definitive event horizon but a Schroedinger like area of decreasing probability. I believe the issue was with quantum mechanics. The concept of a definitive event horizon dictates that any mass or energy which crosses the horizon is gone. This is opposed to quantum mechanics which gives mass or (especially) energy the ability to almost cross an event horizon but not quite.

      I don't know why these physicists had 30 years of trouble with it. Consider magnetic probability fields illustrated by concepts similar to Schroedinger's Equation. There is no event horizon for the probability field of electron distribution. Why should there be one for a black hole?

      Ok, so i agree that Physics needs math...that i have no contention with.

      However, the claim that Physics is hard...well...i don't really know about that.

      Doing physics is really no harder than most anything else. It is certainly no harder than learning a second laguage. The problem of course lies in the fact that it requires more up front WORK. That is to say, people are quite used to learning language. We do it everyday and it is natural part of our lives. Thus, even though it is an extremely complicated tast to accumulate new words and to put them in there correct context, we are used to doing it, and it comes naturally.

      Sadly, however, math is not taught as a language. And so it is viewed as strange and frightening by many people. Thus, math is viewed as difficult -- more so than many other things. This is simply not the case. Once you understand the syntax of mathmatics, it becomes easy to learn more of it. Even easier than most languages, since mathmatics is more self-consistant.

      So we see that the math part is no more difficult that tasks preformed by people everyday. The problem seems to be in the way that math is presented -- as if it is some crazy magic that only the select few can obtain :(

      Now as for the PHYSICAL aspect of physics. I also maitain that is is no harder than most disiplines out there. We are presented with examples of the physical world constantly, thus, physical laws (at least the classical ones) are quite intuitive.

      Of course non-classical physics is a whole nother ballgame. But here, again, it relies heavily on mathmatics. And by understanding the laugage of math, you can grasp the concepts of non-classical physics quite well (or at least as well as can be expected by most).

      Now of course, there are people that understand physics extremely well, and to get to there level, it would be quite difficult -- or impossible. But this has nothing to do with the subject material, but rather EVERY disiplin will have savants -- poeple that rise well above those who share their feild. This is just a result of hard work with a natural proffeciency in that field.

      The point being of course that math is not taught well in school. And so, it takes much WORK, to get used to the laguage. Just as it takes much WORK, to learn a foreign language. The amount of work required says nothing about its difficulty, but rather how unfamiliar the subject is.

      Perhaps this whole post seems like i am just splitting hairs. After all, who cares if it is work vs. difficulty. After all, arent' they the same? Perhaps. It is just that sometimes, i feel people mean that physics is hard = if you are a physicist then you are smarter than an english major. Which is rediculous. So i suppose i am just ranting trying to say that there is no reason why one particular feild should be automatically put above another, baised on perseived superiourity in subject matter/difficulty.

Using the theory of quantum electrodynamics, one can calculate constants of nature from first principles to better than 12 decimal places. These theories are "right," even though there might be some improvement or refinement that comes along later.

    That's the end of my general rant. Now to address specific things you said that were, quite ironically, complete baloney. You say general relativity (GR) hasn't been tested. Einstein's first prediction using GR concerned the deflection of light around the sun during an eclipse. His prediction was different from what others were saying, and when the eclipse of 1919 finally came, Einstein was vindicated. GR passes major experimental test #1.

    Do you have GPS in your car? If you do, you may be surprised to know that those things rely on the mathematics of GR. Without taking into account some of the terms that pop out of the equations of GR, your GPS would never be able to locate you. But it can, and hence GR passes experimental test #2 with flying colors.

    Finally, I point you to the Nobel Prize's page on Russell Hulse and Joseph Taylor. They found experimental proof that two stars orbiting each other were decaying at a rate exactly in accordance to what had been predicted years before. This is a very stringent test of the validity of GR -- the stars were orbiting each other near the "strong field" where gravitational effects are really strong, and hence where any deviation from the behavior predicted by the theory should be obvious -- and, once again, GR passed the test like an Asian kid taking math.

    A certain amount of skepticism is always healthy, of course. Do I think there will be eventual refinements to GR? Of course, probably in the form of superstring theory. But before you go around proclaiming that it's all baloney, you better figure out what you're talking about.

      NB - while large black holes (several solar masses) would take a very long time to evaporate, physicists have a hunch that "mini" black holes also exist. These aren't formed from collapsing stars but from quantum fluctuations in the vacuum. Mini black holes would last a much shorter time - nanoseconds or milliseconds - so if we could just find one, it might be possible to test the theory.

    I hold that quantum theory is entirely a guess based on possibilities because we currently cannot (and perhaps never can) get true facts on the matter so that real analysis cannot be done. I don't know if anyone has any objections to this but I'm not sure if people realize it.

    Take any level of physics, and only allow yourself to view it from a level above. You can come up with some good guesses as to how things will work which might have a very high degree of accuracy even 100%, but you are really just guessing. A simple example is that modern theory states that any two solid objects can pass through each other without interfering with each other at all-- it's just extremely improbable.
    As a parallel: If you look at any scene in a 2 dimensional perspective you'll see objects passing through each other all the time (behind and in front although to 2d it's the same space). Now if the universe was 2d we could say that everything exists on the same 2d plane and any objects passing through each other is known to be impossible, but we know there's a 3rd dimension so to us it's entirely possible, even though everything in that universe is on the same plane. Well everything in this universe is in the same space, that is, they are all on the same 4th, 5th, 6th etc dimensional coordinates-- but that can just as easily change.

      Basically, if you have a gas of about 10^23 atoms (an 'average' sized ensemble), each atom has 3 degrees of freedom, and hence each atom can be precisely described by 3 position and 3 momentum variables. Now multiply that by the number of atoms to get 6N-dimensional phase space.

      Since it's a free 'ideal' gas, there are no interactions or potentials, and the energy of the system is determined solely by the momenta of the particles (p^2/2m for each particle). The energy hypersurface from the sum of all these p^2 terms forms a 3N-dimensional sphere (assuming all particles have the same mass). If the energy of the system is well-defined, it must lie somewhere on this hypersurface of (3N-1) dimensions. Break the 'surface area' into small cubes of uncertainty deltaP*deltaQ (limited to hbar in the quantum (or semi-classical) limit), and you can get a good count of the entropy. To get the ideal gas law, relate volume-derivative of entropy to the pressure, and voila.

      Okay, way off topic, but it's a really cool method, at least when you first see it. It's totally mind boggling to consider surface arae of such a large-dimensional object like that. In fact, it can be shown that as dimension increases bigtime, it's damn near impossible for a random point on an N-dimensional sphere to be in the interior of the sphere (unlike 3 dimensions, where it's more likely to be in the interior than a 'shell' on the outside).

      The ideal gas law is much more easily derived if you take Boltzmann's equation (S=k*ln(W)), where S is the entropy associated with W states and k is Boltzmann's constant. W can be any function that accurately describes the kinds of states you can have (Bose statistics or Fermi statistics).
      Realize that dS=dQ/T=(pdS/pdT)V *dT + (pdS/pdV)T *dV, (dQ is heat added reversibly, T is temperature, pd is partial derivative, and the first partial (pdS/pdT)V is partial of entropy with respect to Temperature while holding volume constant. (pdS/pdV)T is partial of entropy with respect to volume while holding temperature constant.

      Then take the definitions of heat capacity at constant volume, Cv=(dQ/dT)V = T*(pdS/pdT)V. And then one of Maxwell's relations, (pdS/pdV)T = (pdP/pdT)V.

      Combine like terms, integrate, and you'll get P*V = n*R*T (R shows up from the use of Cv, and n shows up because you take it on a per mole basis). Or you can leave Boltzmann's constant in there, k, and you'll get P*V=N*k*T. Where N is the number of atoms in the gas.

      R (the universal gas constant) is just N_A (avogadro's number) times k (Boltzmann's constant).


      In my mind (I'm a fluid mechanics guy), the approach I presented is much simpler and more intuitive than trying to visualize a higher dimensional sphere. Plus the approach I presented fits in nicely with the rest of fluid mechanics. If you need to include relativistic effects (say in nuclear weapons research, fusion research, or to describe plasma physics-like systems), you will need to realize that P = N*k*T/V = 2/3 * u (for non-relativistic gases), where u is 1/2 the average gas momentum times * N. For relativistic gases, the relation is P = 1/3 * u.


      Alternatively, you can take the average pressure due to the motion of particles in a gas as P_avg = k*T*pd(ln(W))/pdV. Where W is the number of states, pd is partial derivative, V is volume, T is temperature, and k is Boltzmann's constant.
      Integrating gives you P_avg = 1/3 * n*m*(v_avg)^2. Where n=the number of particles, m=the mass of a particle, and v_avg is the average speed of the particles. From there you can substitute terms to arrive back at P*V=N*k*T. You can integrate and substitute to get this from the original average pressure in terms of particle motion, but the v_avg^2 form is shown to help with understanding and visualization.

      Picture him in his horizontal plane and a sphere floating above it. Now picture the sphere moving down and passing through his plane.

      The he would see a point appear out of nowhere when the bottom of the sphere first touches his plane. That point would expand into a circle. The expansion would slow until the sphere was half way down. The largest circle he sees would be the equator of the sphere. The circle would then contract down a single point and then vanish as the top of the sphere passes below his plane.

      To a him it would look like a 2D circular balloon appearing, inflating, contracting, and vanishing.

What you need to imagine is what you will see. You will see much the same thing he saw when a 3D sphere passed through his space:

    Not even going to pretend to understand Hawking's latest result, but the black hole information paradox that the bet was originally about is pretty straightforward to explain:

    The original GR picture of a black hole is one in which nothing within the event horizon has any causal connection with anything outside. Once something falls in, it's lost to the rest of the universe forever, there's no way it can send you any information. So basically lots of information would end up inside a black hole and not be able to get out. This was not in itself a problem.

    However Hawking came up with Hawking radiation - the idea that black holes actually radiate, losing their energy (hence their mass), eventually evaporating completely. As I (don't really) understand it, Hawking radiation is a solution that arises from modelling quantum field theory in the region of the event horizon (there's a hand-wavy version which talks about particle-antiparticle pairs, but it's pretty unsatisfying IMHO). It hasn't been witnessed and isn't likely to be any time soon (Hawking radiation would be swamped in the radiation due to matter heating up as it spirals into a black hole), but the theory seems quite widely regarded as sound.

    So it seems the energy that falls into the black hole eventually leaves again via Hawking radiation. The problem though is that this radiation is purely blackbody - it's just a thermal spectrum that gives you no information about the properties of what fell into the hole. Throw in a dictionary or a rock of the same mass - the Hawking radiation which eventually comes out looks the same. It looks like the information is lost forever

    This is in direct conflict with quantum mechanics which states that the evolution of physical systems is unitary - information about previous states is never lost (however hard it may be in practice to retrieve it). The conflict itself is not necessarily a big shock - people already knew that GR and QM weren't fundamentally compatible as they stood. But the question remained as to whether the information was really lost or not. This is what the bet was about (incidentally John Preskill whom it was with started out as a particle theorist, became very interested in the information paradox question, and through that moved into primarily researching quantum information theory - quantum computers and the like) and what Hawking claims to now have answered.

If God created and controls the universe, it is philosophically valid to view the laws of science as regularities we have observed in the way God choose for things to unwind. At one job, I used to quite consistently wear a T-shirt to work always and only on Fridays, and a co-worker joked that he didn't need a calendar to tell whether the weekend was coming up; he could just look at what I was wearing. This was a perfectly regular behavior according to his observations; he could have made a mathematical formula to predict it. However, if he had, this would not have in any way forced me to wear a T-shirt on Fridays or to wear something different on other days. Going back to God, when God behaves in a way that doesn't fit the expectations and that makes an exception to natural law, this is known as a "miracle".

    On the other hand, uncertainty gives a whole extra level of leeway. Suddenly, there are an infinite number of possible "correct" ways (according to the laws of physics) for events to unfold, so as long as God chooses one of them, his actions don't disturb the natural order that has been established. (Why God would want to do this is another question, but one possible answer is to avoid making things so irregular that we cannot plan our lives and have some measure of control over what goes on around us. If we couldn't do that, it would be pretty chaotic and hard for finite creatures like humans to cope with.)

    Also on this subject, there is the fascinating (to me) question of whether it's possible to create perfect physical laws and have all the necessary data to predict future events and have this all happen within the universe. This gets into all kinds of fun things like information content, density, etc., and it touches on the field of data compression. One thing we learn from data compression is that there is no such thing as a lossless compression algorithm that *always* compresses its input. (If there were, the consequences would include the ability to infinitely compress all files, and the ability to solve the unsolveable Halting Problem.)

    But, it is still possible to create a lossless algorithm that losslessly compresses some inputs and losslessly expands others. So, to extrapolate (somewhat wildly) to the physical universe, it would seem the case that the universe cannot predict itself in all possible universes, but it may be possible that some universes could exists where it'd be possible to perfectly model the universe (and thus predict the future, etc.) from within the universe. If we should somehow discover that we live within one of those universes, then would really could fit the entire universe into our brains! Or at least some larger system that involves brains, computers, etc. It would be incredibly surprising to find out that we do live in such a universe though. (Which would be nice if it happened, since thenceforth nothing else would ever have to be surprising.) Anyway, the point is my gut tells me we cannot perfectly model the universe from within the universe, although it is not proven.

    The Euclidean path integral over all topologically trivial metrics can be done by time slicing and so is unitary when analytically continued to the Lorentzian. On the other hand, the path integral over all topologically non-trivial metrics is asymptotically independent of the initial state. Thus the total path integral is unitary and information is not lost in the formation and evaporation of black holes. The way the information gets out seems to be that a true event horizon never forms, just an apparent horizon.

    The Euclidean path integral is the latest trick in quantum gravity.

    The original problem with quantum gravity was that as you "quantitized" space into discrete units, explaining gravity in terms of particles like 'gravitons' and trying to do the math was possible for simplistic interactions like tree diagrams where time generally flowed one way - but extremely hairy and full of infinities if you started looking at loop diagrams where time can flow both ways.

    So people like Roger Penrose came at it from a different direction, starting off with definining space-time in a quantitized manner (spin networks, quantum foam, whatever you want to call it) which had the side effect that complex examples of spin networks acted a lot like 3-dimensional Euclidean space.

    Once people started talking about space-time like this, math started showing up that helped describe events and the progression of events in this space-time, including the Euclidean path integral which attempts to measure the end result of an interaction of particles in this type of space-time.

    But the world is more complex than you think and doing the math for "the real world" shows that the closer you get to the end result, the less and less predictable the end result will be, even though overall it looks like it has a defined end result (i.e. it looks like it _should_ have an event horizon). In reality it's constantly shifting around - and likely this amount of shifting around is representative of the original information/particle system that went into its formation but you won't be able to trace it backwards and extract what the original information was.

    This will probably tie into time dialation which will make it be: We never get to the end result event horizon that 'should' be there and in the process of never getting there, the black hole will have a nice jiggly event horizon as a result of all that information - but so jiggly we can't tell what went in to it, all we can do is measure the jiggliness.

Right now, as far as I'm aware, there is no way to falsify Hawking's idea on information destruction in black holes. Therefore, to my understanding, Hawking's idea cannot be a theory. Where am I wrong here?
    My feeling is that theoretical physics is pretty useless when it is being used to describe something that can not be realistically verified. I mean, with black holes, we think we've detected them but there's not even any real solid proof that they exist at all.

    No theory is ever proved to be true. Theories are only proved to be false. Strictly speaking, we can't even prove that the universe has any physical existence outside our own perceptions, which we cannot prove to be reliable. Verification comes in the form of tests of the predictions of a theory (quite a few of which have already been passed by black hole theory). And mathematically deriving the consequences of a theory is the only way to come up with such tests. In recent years, for example, physicists have managed to test aspects of quantum theory that were once considered to be outside the range of possible verification.
    I understand that a theory cannot be proven, only disproven (or shown to be inconsistent with experimental results). I also understand that there may be some time in the future that we can test Hawking's idea. But I don't consider this to satisfy the requirements of being a scientific theory.

Because none of us could pay the penalty and live, God, in His love for us, provided the way for our debt to be paid in full. He sent His son, Jesus Christ, to die on the cross in our place, that we might have salvation and the eternal relationship with God He created us for.

By saying now that matter 'leaks out slowly in a mangled form' but leaving out the way it was mangled, my math gut is telling me that this mangling may be the result of light's assymtotic approach to zero resolved velocity as it approaches the event horizon of the black hole. This is approaching the limit of infinite slowness through negative values. Now if some of the photons actually fall back to the singularity, some could say that inasmuch as the gravitational acceleration must needs meet or exceed 'c' for this to happen, then the velocity of the falling photons could well exceed 'c' at the point of arrival at the singularity; but this is beside the point.
    When any wave like this is 'slowed down' the percieved frequency is lowered as the information flow is retarded by the deceleration. This could account for the percieved 'mangling'. It would be like a time dilation literally set and made permanent. This is where the so called universal matter and energy 'speed limit' break down. Larger and larger 'black holes' should by the certainty of mathmatics have larger and larger gravitational acceleration values. If 'c' can be approached or even equalled for small black holes, what then for large ones, not to mention galactic or even larger ones. It is my 'gut feeling' that somewhere along the line Herr Einstein divided by zero whether he realized it or not.

Astronomers routinely find evidence of superliminal velocities during the conduct of their jobs. They just as routinely and unthinkingly apply 'corrections' to their observations and report the results as 'facts'.

True conservation laws might later have to consider a larger definition of the overused word: "universe".

    scientific postmodernity ... is that self-contradictory?

    It is "absolutely right" in the sense of getting the correct result ... just like (11+2) mod 10=3 might be derived by noting that 11 is 3 in base 2. It's completely wrong, but it works in this scenario.

    "Myth has very definite characteristics, such as fanciful creatures, that mark it as myth. The Jewish account as recorded in Genesis bears no similarities to myth."

    Last time I read Genesis it featured a talking snake and a mystical apple... That matches your parameters of a myth rather nicely.

    "Evolution holds we are an accidental creation of random chance actions because it then frees its believers from reponsibility for their actions"

    No it doesn't. It has absolutely nothing to with "freeing its' believers from responsibility". It's a scientific theory. Not a way of life.

  177. On South Africa and cricket by rooijan · · Score: 1

    Thanks for the website compliment - I try :)

    In Zimbabwe, yes, there is a dismal failure. I wouldn't put it down to race relations all that much though, although they do play a part. Bob Mugabe (the president) is severely abusing his own people, most of whom are black, as is the majority of the political opposition. Personally I think he's simply grown power hungry and arrogant. My own country's relationship and attitude toward him I find shocking and disgusting, treating him like there's nothing wrong, but I have no reason to believe that what has transpired in Zimbabwe will repeat themselves in South Africa - we don't have a Mugabe.

    In South Africa I don't see overwhelming trouble in the near future. Economically we are growing, but too slowly. This can only worsen when Aids starts hitting our labour force (this sounds heartless, but it is the bigger picture. Obviously I feel for the human element as well). This will hurt our economy, certainly. However, I don't think the country will descend into civil anarchy or anything like that - if anything I think the overall situation will improve despite all these problems.

    The government appears to be beginning to get a handle on many issues which have plagued the country since democracy in '94. It is widely predicted that the ruling ANC, which currently has 70% of the vote and accordingly the 2/3's majority they need to pass any bill in parliament, will not see a majority anywhere near that big again. Accordingly politics will become more representative in the near future (say after two voting periods - 10 years), where the ANC will be in charge most likely but the other parties will wield considerable parliamentary influence as well. This can only be a healthy and good thing for a democracy.

    Let me put it this way: I'm a white male Masters student at a South African university, and I have no intention of leaving the country when I graduate. I feel positive about the country's prospects. A good intro to the country can be found at this site, while this is the official internet gateway to the country.

    Onto the cricket...

    Yes, a Test cricket match, one of the two major international varieties, is scheduled to take 5 days. The other version takes about 6 hours, while a newer, shorter version recently introduced takes about 3 hours. The basic rules are explained here much better than I am capable of doing so. I personally think it is the most awesome of sports, which may of course be slighly tempered by the fact that South Africa is quite good at it...

    An excellent cricketing link if you have a further interest is here.

    Hope this is concise enough. Always a pleasure to spread some info about my home or my favourite sport!

      OK, I think I have the basics of cricket down, seems semi clear now. I can see why it takes so long.

      Just watch out for the complacency on political events. I have seen it change in five minutes inisde the US, been caught in the middle of pretty extensive riots twice now, one of the times I definetly needed to be armed, if I hadn't of been, well, most likely not typing this missive right now. Pretty scary stuff, one minute normal, few minutes later people getting beat, cars on fire, shops being looted, etc and I was definetly the wrong hue to be in the area. Mr. 357 helped me out a lot at that time... Had to go back into the thick of it twice, once to rescue a girlfriend I had at the time,who was working in the middle of the riot area, then we had to go back in and get her mother, who was ALSO working in another building in the thick of the rioting. Dang cops did NOTHING while all this went down for hours, not a darn thing, didn't stop one person getting beat, one store from getting looted, etc. Political correctness ordered from the (black)mayors office, and I know this is so because I questioned some cops about it. they were disgusted too, but were ordered out of the area and told to just let the rioterts do what they wanted to do..

      When we got back from the rioting to our apartment, about 4-5 miles away from the rioting area, we got together the local "neighborhood watch" loosely defined because we were the only aware adults in the block, it was very young people or old retired geezers basically, anyway, that was me, a roomate, and two guys we knew on the next block over, and we packed the vehicles and got ready to convoy out, and sat back an monitored it live on the TV. We never did have to, but we discouraged some cruising gangbangers looking for a fight or some rape sport or some looting from rioting in our block,they came driving the block looking for trouble, and the sight they got of well armed and obviously annoyed adults standing around with heavy rifles and starring hard at them was enough to send them off a-rioting someplace else. ;)

      word to the wise, it never hurts to own a defensive arm, because you never know when it might come in handy....besides, target shooting is quite good fun!

      Anyway, I always though SA would always do the best in africa,looks like it is by the webpages there, it has too much going for it. Zimbawe looks like it will totally collapse soon, I have no idea why europe and the US don't do something there, there's going to be even more massacres shortly I am afraid. When I was younger I considered going there when the fighting was still going on, but decided against it at the last minute when it became obvious they were going to lose to the goons who are in power now there. I thought "hmm, bad idea right now".

    The other point of a black hole is it being a 'hole'
    (Must not make goatse joke here)

    From my naive understanding of the physics involved in this, mass has a tendency to cause a dip in space and time, like a marble or basebal on a blanket, but thats only in 2 dimentions instead of 4 or 5 or however many there really are. The more mass the object has, the more significant the dip. Gravity isn't the idea that matter attracts other matter, it is the dip in the blanket. And if you put a big err heavy enough object, it will rip a whole in the blanket.

    So, as an SF geek I got to ask, what happens when you go through that whole?
    Is it a portal into another universe? Does the black hole itself create a new universe? Or is it just a really really dense object that is getting more and more massive?

    In the end will there be nothing left in the universe but a bunch of black holes? Will the black holes attract each other to form one really big black hole? If that happened would that result in a big crunch that would then turn into a big bang?

    Or are these ideas just a joke?
