Possible Hole in Black Holes

jd writes "Researchers have found what they believe may be a MECO (Magnetic, Eternally Collapsing Object) inside of a quasar. MECOs are rivals to black hole theory and involve plasmas that never reach the state of being a singularity. The most obvious differences between them are that MECOs have a magnetic field and do not have an event horizon. The problem lies in that the Universe cannot have both MECOs and black holes — it can only have one or the other. If this object truly is a MECO, then black holes do not exist. Anywhere. (Furthermore, this would require Professor Hawking to return a year's subscription to Private Eye and give Professor Thorne a year's subscription to Penthouse.) On the other hand, if this thing isn't a MECO, it's behaving very very oddly for a black hole."

    Why can't the MECOs and the black holes just set aside their differences and peacefully coexist?

    Seriously, if this thing really is an MECO then what are all of the things that we've thought were black holes?

      All good and fine. But if we have decades of good work with black holes and we've appeared to find quite a few of them, then why would we be throwing them away with just one possible MECO sighting?

      I mean, if all of a sudden my very smart next door neighbor told me the sky was purple, I'd have to give his account much more scruteny than normal, simply because I already have so much evidence that it's blue. I certaintly wouldn't elevate it much past "interesting" until I got a lot more information, and I'd certainly not discard blue until there was a great body of evidence.

      Because the two are mutually exclusive.

      Black Holes are (or have, depending on how pedantic you want to be) singularities--that is their defining characteristic. No one has ever "seen" a singularity. What we see is indirect evidence for objects that are compact and too massive to be neutron stars. The theoretical upper limits on neutron star masses is quite strong, so we do not believe they are neutron stars.

      When a fairly massive star collapses, it stops when the density gets high enough that repulsive core of the strong force dominates gravity. When a really massive object collapses, the strong force is not strong enough, and the collapse goes on unimpeded, which creates a defect in our coordinate system known as an event horizon.

      The thing is, if there is something that could interfere with the collapse, then the collapse would not occur. Apparently MECO theory includs something that will do this. I have no idea if it is right or not, but if it is it provides a generic mechanism that will operate in all collapsed objects, so none of them will ever get to the singularity stage.

      Proofs that Black Holes exist have always been a matter of elimination--it isn't a duck or a neutron star, ergo it must be a Black Hole. If there is another viable alternative, the proof goes by the wayside until more information is discovered.

      Blah blah blah. By that standard, no scientist in any field can "prove" anything -- you can't prove that it is not the case that the Universe was created five minutes ago by a deity that's having fun with his creations making them think that it's anywhere between six thousand and several billion years old; you can't prove that it is not the case that our eyes are completely deceiving us and the air is actually filled with floating jellyfish that want to eat our brains; you can't prove that it is not the case that "bacteria" and "viruses" are actually a clever Freemason conspiracy to hide from the rest of the world the truth that disease is caused by an imbalance of bodily humors ... etc. So keep enjoying your fantasies. Meanwhile, those of us who rely on data collected by observations made to the best of our abilities, and rigorous theories representing the state of current knowledge, will go on doing our best to understand the world around us.

    Cosmology isn't my field but the data here is incredibly vague. I'm not sure this deserves more than a raised eyebrow and an "Okay...now come up with something a little less tenuous".

  5. let's side with caution for now by N3wsByt3 · · Score: 4, Insightful

    Ok, when we have, like, numerous observations of black holes (which, granted, have only been 'seen' indirectly, but which follow the predictions quite good and at least in one instance, have observed it directly enough to rule out anything else then a black hole) and just one observation of a MECO - especially when scientist themselves say it's not totally convincing - then logic dictates that it's more likely the black-hole theory is correct.

    Until further obervations is being done and it is being confirmed it's truelly a MECO (or other MECOs are observed), then we really can't get say anything beyond wild speculation (which is what slashdot is very good at ;-).

    Most probably, it will turn out to be not a true MECO, but rather an odd variant of a black hole.

    If it DOES turn out to be a MECO, then, as theory predicts, there can't be any black holes - so then all our past obsrvations must have been wrong or misinterpreted. And if it turns out we have MECO's AND blak holes...well, then something very, very, very wrong must be going on with our current understanding of the universe and all the theories thusfar.

    Which, actually, would be a fantastic thing to science, contrary to what some might believe.

  6. The third option by Gerzel · · Score: 5, Insightful

    Lets not forget that there is another alternative to one or the other theory being right, and that this alternative is far more likely, almost certain in fact.

    The option is that neither of these theories are correct or rather neither is entirely correct. Both may still be partially true, and probably both are to a certain extent.

    Newton was right on with his theories, yet they were proven to be incorrect, and they are still the first thing a physics student learns today. I find the idea of "if phenomina A exists then phenomina B, that we have also have some evidence for, cannot exist" because when you get right down to it we don't understand our universe we perceive it.

    I wouldn't worry to much about this. As the article clearly states all observations were made with an optical telecope. They saw this mysterious "hole" in the center and made the assumption that there was nothing there. It could be full of hot gas but you wouldn't be able to detect it with a visible light telescope becasue the gas itself would not not emit any light. This is kind of like the monty python sketch where it was agreeded that a duck is made out of wood becasue it floats.

  8. The truth is somewhere in the middle by MarkusQ · · Score: 5, Insightful

    The problem that the grandparent pointed out is very real. While we need to assume that "the state of current knowledge" is sound and trustworthy to do any engineering it is fatal to make that assumption in science.

    I had a friend who made a minor discovery while in undergrad, simply because he didn't fudge his data in a lab assignment. He got graded down for it, and decided to redo the experiment. When he got the same results, he started asking around and found out that quite a few of his classmates had also gotten the results he had, but written it off to "experimental error" since it didn't match the predicted outcome. He took this back to the professor, and challenged him to actually do the assignment himself. They wound up publishing a joint paper on it, but to me the most interesting realization was that, for all the years that assignment had been given, nobody else had caught the error in the accepted theory.

    By all means, if you have to bet on the outcome of any particular situation, go with the current state of knowledge. But if you're asked if our current knowledge is correct in its entirety, bet heavily that it is not. And if observation doesn't match the theory, don't lock yourself into the assumption that the data must be wrong because the theory couldn't possible be.
