Mysterious "Cold Spot": Fingerprint of Largest Structure In the Universe? 94

astroengine writes At the furthest-most reaches of the observable universe lies one of the most enigmatic mysteries of modern cosmology: the cosmic microwave background (CMB) Cold Spot. Discovered in 2004, this strange feature etched into the primordial echo of the Big Bang has been the focus of many hypotheses — could it be the presence of another universe? Or is it just instrumental error? Now, astronomers may have acquired strong evidence as to the Cold Spot's origin and, perhaps unsurprisingly, no multiverse hypothesis is required. But it's not instrumental error either. It could be a vast "supervoid" around 1.8 billion light-years wide that is altering the characteristics of the CMB radiation traveling through it.

      That does not make any sense. How could a 1.8 billion light-year supervoid be anyone's mother? Furthermore how could it be a mother of someone on Earth?

        The Supervoid is far too warm to be Comcast-related. Comcast HQ is somewhere in the -1K range.

        He stood there in his multiverse lab, shaking the tube with that new mixture of fundamental constants and just when he added a spoonfull of antimatter reductor something unfortunate happened and the whole thing went "bang" in a very bad way. He was super fast to duck down for shelter but the shockwave was faster and caught him rolled up like a ball.
        Thus the resulting universe has been god-forlon right from the very beginning.

      Each Kolob-day is as 1000 years of ours, (at least, wikipedia claims that is the description of the Book of Abraham), so a point on its (rotational) equator travels 1000 light-years at most per Kolob-day; that's 9.5e15 km, so the diameter of Kolob is restricted to 3.0e15 km at most, and 1.8 billion light-years is equivalent to 1.7e22 km; so the Cold Spot is ~ 5.7 million times larger than Kolob is allowed to be by the speed of light.

    Furthest-most? When "furthest" is just not far enough?

    This is the worstest made up word I've seen in a long time.

    • Yeah, it's bullshit-nonsense. Stupidest-most thing I've seen all day.

      • Fuck, I only just noticed. TFA is not on some retarded blogger-blog, but on the Discovery Channel website. They have really and utterly gone to shit.

    • Furthest-most? When "furthest" is just not far enough?

      Technically it should actually be "farthest" since it refers to a physical distance whereas "furthest" means most distant in a figurative sense. For example you say "furthest from the truth" not "farthest from the truth" but "Cape Spear is the farthest east you can go in Canada" not "furthest east". So to summarize: "furthest-most" should not have a hyphen, should not have the 'most' added since it is redundant and finally should actually be "farthest" since it refers to a physical distance.

      As for the o

    I seem to be limited to reason. When space is defined as nothing I have all kinds of issues with nothing having an effect on a big pile of something. Maybe we need to get rid of the word space and go back 150 years and call space the ether or some other mysterious material. Or i could just make up some babble that some people will pretend to understand. Example: Space is the expression of the differential between dark matter and matter acted upon by both energy and dark energy. Now freshmen light you

    The universe is full of voids - large regions of space empty of matter. Ever since the detection of the Cold Spot, it's been speculated that a "supervoid" could be responsible, but it was thought that a void that large would not fit current understandings of structure formation - essentially trading a too-cold spot in the CMB for a too-big hole in the matter distribution.

    But this work, which was made public a year ago and just now got through the referee process, showed that there *is* a supervoid in the direction of the Cold Spot. They found it by looking at the distribution of galaxies in that direction. It turns out that it is a big void, but not very empty; more like a wide shallow dish than a small deep bowl. This can both explain the Cold Spot and be compatible with our understanding of how structure forms.
  • The universe is shaped as a donut. They have found the hole!
