Astronomers Find Huge Hole in Universe
realwx writes "Astronomers are surprised by a recent discovery of a space hole that is nearly a billion light years across. "Not only has no one ever found a void this big, but we never even expected to find one this size," said researcher Lawrence Rudnick of the University of Minnesota. Rudnick's colleague Liliya R. Williams also had not anticipated this finding. "What we've found is not normal, based on either observational studies or on computer simulations of the large-scale evolution of the universe," said Williams, also of the University of Minnesota.""
One of the fundamental approximations in modern cosmology is that the universe is both isotropic and homogeneous over large scales (such as those which treat galaxies as point objects). This size hole s fairly big, and is noticeable on even this scale. This means there could be a special point in the universe, which caused all sorts of problems. Does this mean we have to re-think our basic theory of cosmology, or is this size hole possible under current theories, even if it is extremely unlikely to form. (the universe is a big place, even if something has a minuscule probability it still could happen somewhere out there. Personally I think it was placed there by the universe to test our belief in God not existing.
"We don't know one millionth of one percent about anything" -- Thomas Edison. Think about it. Light travels roughly 5.8 trillion miles in a year. Our galaxy is about 120,000 light years across, give or take 40,000 light years, and it contains an estimated 100 billion stars (scientists are only guessing; they can't see them all). This newly reported area of "dark matter" (translation: uh, we don't know what it is), is a billion light years across -- a billion light years. Any attempt to place definitive explanations on the origins of the universe, its size, how it is expanding (or not), and what fills it, is an exercise in lunacy. We're like blind people feeling away in the dark and trying to describe what we can't even touch. We don't even know what a black hole is; we're only guessing based on what happens at the event horizon. Science is a great discipline -- I fell in love with it even before college -- but the scientific community needs an enormous dose of humility; and that's not something I see a lot of these days. Every news story that I see about scientific discovery is more often than not missing huge qualifiers, such as scientists theorize that... Think about it. The laws of physics that apply to us here and in the space that immediately surrounds our infinitesimally small portion of our galaxy may not apply in other regions of the universe -- of that I'm convinced based on what we can't explain. It's an amazing universe. Personally, I can't wait to see what we stumble on next.
