    Dark matter as matter in parallel universes

    Uh huh, yet they predict and let us develop technology for all that it lacks the elegance you seem to want.

    Dark matter as matter in parallel universes

    The laws of physics seem just fine, but our understanding of them leaves something to be desired. Why is that surprising, and why do you think the solution is anything other than the natural evolution of existing theories and development of new ones? Where does metaphysics enter the picture...

    Dark matter as matter in parallel universes

    I'd agree with that; it's hard not to become enamored with these ideas, but it's also hard not to fall out of love with them given time and reading. It's one of the joys of science that you get these amazing concepts to bat around, but the other side is the need for rigor. Without any hope of...

    Dark matter as matter in parallel universes

    It's not 100%, but it's pretty fat nail in that coffin. A lot of the "Dark" stuff other than matter is used to justify any number of pet theories; tread with care.

    Dark matter as matter in parallel universes

    I was under the impression that 'Dark Flow' is at the level of, "might be something, might be an irregularity on the image."? It seems everyone uses this one to justify some claim, from colliding universes and more. In terms of established science, you seem to be going on with a bit of nonsense...

    Dark matter as matter in parallel universes

    How can a multiple universe theory of dark matter POSSIBLY be LESS complex? You'll need to include all of the elements of the a one-universe cosmology, and in addition you have to figure out how two spatially and temporally separated bubbles interact in what seems like a pretty uniform manner...

    Dark matter as matter in parallel universes

    I'd add the quantum suicide issue, that until I have some assurance that dying, or for a more local example, being teleported Star Trek style isn't the same as dying and being replicated, I'll pass. If dualists are right, there are some serious questions, and if materialists are right, there are...

    Dark matter as matter in parallel universes

    Yeah, and that's art, not physics which should be an empirical endeavor and not an argument over taste. The issue isn't believing in collapse, or MWI, or anything else... just work the equations; that's what SUAC is! Metaphysics is plenty of fun, but it's become this serious endeavor on par with...

    Dark matter as matter in parallel universes

    There's nothing at all wrong with thinking about it, but there's thinking about it, and forming armed camps; I see far more of the latter.

    Dark matter as matter in parallel universes

    I mean exactly what I said: "shut up and calculate", not worry about collapse unless decoherence is the focus on your study. The solution to a falsified theory is not to invent countless interpretations of a theory, a majority of which are not falsifiable even if they are elegant. The solution...

    Dark matter as matter in parallel universes

    MWI has fewer than other interpretations except the only one that has any evidence to support it: shut up and calculate. I don't understand why people think they're going to form a valid ontology based on a theory which is not a "final" theory. Occam's Razor cuts closer to the bone than an...

    Dark matter as matter in parallel universes

    Let me rephrase: the notion of an infinite number of universes is not subject to Occam's Razor if you believe in eternal inflation, or a multiverse of many isolated pockets. It does cut finely (I think) in the case of QM interpretations such as MWI where it's just another variable to remove the...

    Dark matter as matter in parallel universes

    It doesn't exactly bowl me over than a name from Star Trek would be something you find cropping up in more than one forum related to science in general. I keep hearing in this thread about dark matter as a product of universes other than our own, but even if possible (and twofish-quant has...

    Dark matter as matter in parallel universes

    Interesting, I didn't know that there were formulations of parallel universes that allowed for any observable effects in ours; that's pretty cool! If I understand the second part of your response correctly, then you mean that we're basically deploying more sensitive techniques and equipment, and...

    Dark matter as matter in parallel universes

    Then why isn't it uniformly distributed along with "normal" matter?

    Dark matter as matter in parallel universes

    Just to be clear, if something like DM were in a "parallel" universe, we wouldn't see ANY evidence of it because it would be completely inaccessible. By definition, it's part of our universe or it isn't DM, and while it could be all around us right now, its interactions are so incredibly weak it...

    Dark Energy News

    I don't have anything intelligent to add, but this is certainly very interesting and satisfying; not as satisfying as knowing what the hell DE is, but satisfying.

    Information about stars indeterminate?

    To be clear, those are launched though, for instance to study Sol in the far UV, Radio end of the spectrum, magnetic structure, and so forth. There are two solar observatories being used right now, right? I think one is USA, and one Japanese, but I'm not entirely sure.

    Information about stars indeterminate?

    They don't only look at the visible spectrum; you need to do your homework.

    Expansion of the Universe question

    Your view of Dark Matter strikes me as already largely falsified unless GR is wrong about things it APPEARS to be correct about on a huge scale. Do you have anything to support the other views you mentioned, which I have to say, strike me as far more exotic/flat-earth than simply drawing...

    Expansion of the Universe question

    Too true; how often do you hear it described as an "explosion"? No wonder people tend to think of it as something within space-time, instead of the beginning of both, the expansion of both from a pinprick.

    Expansion of the Universe question

    Theoretical? The issue with magic is the same as with a bad theory; lack of falsifiability and support. The need for physics which contradicts existing theories which work, and more. The notion that "before" the big bang or other event is no longer the work of science is a valid statement right...

    Expansion of the Universe question

    Am I reading you correctly, and you're saying that you believe in magic, as in divine or other magic? That's nothing to do with science; nothing at all.

    Expansion of the Universe question

    What on Earth are you talking about, and what does it have to do with universal expansion? It sounds as though you're just talking about your idea of God, nothing more, and that is hardly relevant here even if you believe in God.

    Sorry bcrowell, I guess I did mix up my concepts quite a lot. Thanks for the detailed response, and not letting it slide.

    White holes

    Yes! This is really a good way of thinking about it; it's not really a thing anyway, just a demarcation between what can and cannot escape the gravity of the hole. You learn very quickly, it's a pleasure to help; ask any questions you like. For me, black holes were my first love in physics, and...

    Expansion of the Universe question

    What is fueling this expansion, nobody knows, but there are guesses. Maybe it's the old concept of a potential energy curve into a plateau from initial inflation, or maybe it's vacuum expectation energy. Tidal forces from other bodies in the universe act to slow expansion presumably, but not...

    White holes

    The event horizon of a black hole is proportional to the black hole's mass; a stellar mass black hole has a relatively small event horizon. An AGN (Active Galactic Nuclei) is orders of magnitude more massive, with a commensurately larger event horizon. The old way of looking at this would be...
