    I guess we shall find out more over time.

    George Efstathiou, professor of astrophysics at Cambridge, who co-authored the papers setting out the Planck findings, said the suggestion that the data offered evidence for other universes was speculative but "very interesting".

    He added: "Such ideas may sound wacky now, just like the Big Bang theory did three generations ago. But then we got evidence and now it has changed the whole way we think about the universe."

    Already some "anomalies" in the Planck data appear to deviate from the standard expectations, and if borne out, these deviations could point the way toward new physics, scientists say. For example, the basic picture of inflation predicts that the universe should have expanded uniformly in all directions, but the CMB's temperature variations appear to be sixed and spaced differently toward one side of the universe than the other. In addition, the variations don't seem to behave the same on small scales as they do on large scales.

    "It's hard to know what to make of these anomalies," said Lloyd Knox, a University of California, Davis physicist who's leading the U.S. team inferring cosmology parameters from Planck's data. "That these are real features of the microwave background sky has really been firmed up by Planck, but how to make sense of them isn't clear, so there's some excitement about them and some people are going after this as a clue."

    Ultimately, all of the scientists expressed their thrill at being able to plunge into some of the thorniest questions about the universe using the exquisite data from Planck. Right now, they said, astrophysicists have a rare opportunity to make huge leaps in progress, and the researchers consider themselves lucky to be working at this point in the history of science.

    "I don't think you could do better than doing cosmology right now; it's just amazing," Albrecht said.

    Actually Stu - you need to get up to date.


    " A potential portal to other universes seems to have closed. The sharpest map yet made of light from the infant universe shows no evidence of "dark flow" – a stream of galaxy clusters rushing in the same direction that hinted at the existence of a multiverse.

    That is the conclusion of 175 scientists working with data from the European Space Agency's Planck spacecraft. But champions of dark flow are not ready to give up yet, including one Planck scientist who says his team's analysis is flawed."
    ...
    ...


    "The Planck team's paper appears to rule out the claims of Kashlinsky and collaborators," says David Spergel of Princeton University, who was not involved in the work. If there is no dark flow, there is no need for exotic explanations for it, such as other universes, says Planck team member Elena Pierpaoli at the University of Southern California, Los Angeles. "You don't have to think of alternatives."

    Note... one member the team is re running tests because he is might employ a better filter.

    but for now stu - no dark flow... no other universes.

    You missed the point.

    The basis for postulating "fine-tuning/Tuner/Creator/god" is even more unsound (if that were even possible), when the scientifically not-testable multiverse argument it relies upon, becomes scientifically plausible and theoretically testable.

    I would have missed the point perhaps if observing a stream of galaxy clusters moving towards a central point was really a test for our our universe bumping into other universes. And, they had really found other univereses. The idea that someone suggested that idea as a test other universes had a long way to go before it could have really been evidence of other universes IMO

    For now our universe is incredibly fine tuned and the explanation of a multiverse takes as much faith or more than belief in a Tuner.

    No you are missing the point....and it takes science not faith to discover a plausible method of falsifiability where there was none.

    again... you deny logic.

    Until other universes are discovered it takes faith to say that other universes will explain the fine tuning in ours.

    again... you're missing the point

    It really doesn't take faith. Multiverse is a science based, not a faith based possibility.

    What takes faith is no science no scientific evidence, just hoping for fine-tuning and a 'Tuner'.

    teleportation star trek style is now a science based idea.

    until it happens, it takes faith that you could someday be transported to a cave in china, instantly. And I would say that teleportation is hell of a lot less speculative than almost infinite other universes.
