Bubble universes

    The idea of 'Multiverses', Universes that lie in bubbles formed by the big bang has been given a boost by studies of the low temperature glow left over by the Big Bang.

    Studies seem to show that these "bubble universes" left marks on our own universe.

    Further studies will be carried out using the Planck Telescope.

    (Source of information: BBC. Details will be published in "Physical Review D.)

    Cosmology has gotten to the stage where it is hard to distinguish the crap from the good because they both sound equally ridiculous.

    A spherical earth once sounded ridiculous, also did the idea that the earth orbited the sun. Aspirations of going to the moon 1 hundred years ago would have sounded insane probably almost as much so as they did 50 years ago

    Yep definitely but they were also ridiculous with good reason. The curvature of the earth is effectively 0.0001 radian per mile (In fact, you could say a spherical earth is a ridiculous notion too:D). Copernicus' model was fundamentally flawed in that it assumed the orbits of the planets were circular and hence his theory never added up with the available evidence at the time.I'm not sure you get the subtlety of the point. Cosmology today is so counter intuitive that when presented on a plate side by side the surfaces of the genuine and bullsh1t appear the same. Making it a lot easier to bastardise it. The truly utter pseudoscience crap and can be hidden among the genuine and the lay person knows no better. The danger here is that a new generation of scientists growing up could be searching for evidence of a hypothesis that was never part of a theory in the first place.
