The big bang poses a big question: if it was indeed the cataclysm that blasted our universe into existence 13.7 billion years ago, what sparked it?

Three Perimeter Institute researchers have a new idea about what might have come before the big bang. It’s a bit perplexing, but it is grounded in sound mathematics, testable, and enticing enough to earn the cover story in Scientific American (pay-walled), called "The Black Hole at the Beginning of Time".

What we perceive as the big bang, they argue, could be the three-dimensional "mirage" of a collapsing star in a universe profoundly different than our own. SciTechDaily has a decent article about the theory. If you are interested in the math, you can download a PDF of the study from Cornell University Library.

    A claim like that is currently a conjecture. If they find a way to test it, it will become a hypothesis. Only once you actually have really convincing evidence that the idea consistently explains a whole lot of observable phenomena will it become a theory.

    The reason this matters is because of those who like to say that certain scientific theories are "just a theory". Let's use the right words here.

      Indeed. Just because we can write algebras that invoke higher dimensions and can show that the manipulations end up looking like this universe, there isn't any reason to think this is any better or worse than any other conjecture on the matter.

    So the article ends with this:

    Of course, our intuition tends to recoil at the idea that everything and everyone we know emerged from the event horizon of a single four-dimensional black hole. We have no concept of what a four-dimensional universe might look like. We don’t know how a four-dimensional “parent” universe itself came to be. But our fallible human intuitions, the researchers argue, evolved in a three-dimensional world that may only reveal shadows of reality. They draw a parallel to Plato’s allegory of the cave, in which prisoners spend their lives seeing only the flickering shadows cast by a fire on a cavern wall.

    I might just be in a bad mood dealing with people not meeting deadlines and full of excuses this morning, but isn't that a convenient argument used by these scientist: "I know it's absurd, but since nobody can actually know what happened, don't dismiss my conjecture, no matter how out there it might be." It's almost a "No True Scotsman" argument; it can't be not possible because anything is possible in the 4th dimension. It's almost like a religious claim; "You can't touch faith, but when God speaks you know it."

    I suppose the Allegory of the Cave can be called upon anytime you have an outrageous claim...

      Multiverse has always seemed more like religion to me than science.

      With Multiverse we can explain away the creation of this universe with the anthropic principle and just say there are infinite universes, thus one was bound to look like this one.

      With stellar systems it is testable (we can see LOTS of exoplants), with universes, while it may be just as valid a conjecture, there have been no tests that could be performed (that didn't count on conditions that may well not exist, but still wouldn't invalidate the theory). Multiverse just feels like the 'God' of the atheist mathematician to me.

        I'm glad you used the word "seemed". That makes it a plausibly true statement.

        FWIW, every interpretation of Quantum Mechanics that I've run into has ideas that I consider equally counter-intuitive. As long as the interpretation is consistent with the math, I'm willing to consider it as reasonable. The ALL demand that you accept things that can't be proven. The "default", or Copenhagen interpretation, basically says "You can't understand the universe, all you can do is calculate probable results." But the actual predictions made are the same as those made by the Multi-World interpretation. In fact the "sum over histories" approach to calculation created by Feynman essentially explicitly uses the Multi-World interpretation to simplify the calculations.

          I think the problem is when it comes to the very large like galaxies and the very small like quantum we are REALLY in the dark here as there is so much we just don't know or haven't detected. We are like the scientists working with flight at the start of the 20th century or the rocket men of the 20s and 30s, with a LOT of the math having to deal with a bunch of question marks because there is just so much on the subject we just can't explain yet with our current level of technology.

          I think the only thing we can say for certain is that many of the theories we have now will probably be blown to shit when the next detection breakthrough comes along.

      It is an interesting claim though. One that makes some sense.

      If you can get get a black hole in the 3rd dimension. If there are higher dimensions why wouldnt you get them there? If you can get them there what does the event horizon look like is it a 3d construct? Also can we get black holes in 2d and 1d as well? Which would be interesting as a 2d plane should be infinitely thin otherwise it would belong to the 3rd dimension.

      The claim that we are part of 4d black hole though would need some sort of test (which they have?).

      I suppose the Allegory of the Cave can be called upon anytime you have an outrageous claim
      In this case it makes some sense to use it though. As neither you or I can see what the 4th dimension looks like, if it exists at all. We think it does but are not totally sure if it is time or something else. The problem is we are dimension locked. I can not as a 3d entity manipulate 2d space without turning it into 3d space. A 2d space can not interact properly with 3d as it simply can not even 'see' it.

        I had a strange interaction with some aliens one time and when I asked them to take me on their ship, they said that I would not be able to survive being in a 4 dimensional space as a 3 dimensional being. It would be like forcing a plane to touch the complete surface of a sphere. Impossible, even if you could tear or flatten the surface of the sphere, and meet half way, you create another side which then cannot touch as well. The sphere is destroyed, and still not completely touching the plane.

        At least that's the excuse they explained simultaneously into my thoughts.

    I have always thought this theory makes the most sense. If Hawking Radiation is a real principal and the BH is constantly pulling half of an antiparticle pair into the event horizon, then there is a chance that the observable mass the BH pulls in is only part of what it ingests. A BH pulls in a lot of matter ripping it apart and compressing it down to a tiny dense mass of matter. Kinda sounds like the theory of the big bang, an infinitely small and hot ball of matter which exploded. Somehow the BH creates a new bubble of space and when it pops, we cease to see it but the pop is expanding in a new bubble of space. Perhaps this is the end of a black holes life cycle. What we predict as them evaporating might be only on the "outside", the part we see. On the other side is a whole new universe.

    If our universe is the core or inside of a black hole in another dimension. Then shouldn't pieces get sucked in and magically appear that weren't here before? Not necessarily physical matter. It could be clouds of neutrinos, dark energy and other exotic forms. But the main point of it is that it would appear out of nothing. And stay put. Otoh, perhaps expansion of the universe is driven by particles from the outside trying to squeeze in? And which is why vacuum isn't really empty. Could also be that any sucked in stuff is of the wrong dimension to actually have any interaction we can currently measure.

    Perhaps this also means that one can travel outside the visable universe but won't notice anything because the dimensions are different and there will be to little interaction?

      This idea doesn't suggest that our universe is inside a 4D black hole. It's suggested that it may be the event horizon of a 4D black hole.

      Consider the event horizon of a black hole in our universe. This is a firm limit beyond which events inside cannot effect events outside. There is no gradient; it is a hard line. This hard line is two dimensional. It has length and height but no width. It's closed in on itself like a sphere, but it's just the onion skin on the outside of the sphere.

      So, the event horizon around a 3D black hole is 2 dimensional. The event horizon around a 4D black hole would be three dimensional. What would that look like in the 4 dimensional space? I have no idea. It's beyond my ability to comprehend. I can imagine it mathematically just fine, but physically? Beats me.
