If you like Sagan’s concept of earth as a pale blue dot in a vast black cavern of space, you’ll love Dr. Stefan Keller’s take on our local group of galaxies. The Milky Way would be one tiny purplish pixel in the image above. Each lit speck represents a major galaxy, the larger dots are super clusters, thousands to millions of galaxies. The cosmos is revealed as sheets and filaments of starry matter separated by oceans of space-time hundreds of millions of light-years across filled with a thin haze of poorly understood ghostly particles.
We’re kind of sandwiched between two enormous voids which pin us into a filament linked at one end to the big Virgo galaxy cluster and to the Fornax galaxy cluster off to the other side,” Dr Keller said. The structure of the filaments were most probably shaped by interactions between dark and ordinary matter. “A consequence of the Big Bang and the dominance of dark matter is that ordinary matter is driven, like foam on the crest of a wave, into vast interconnected sheets and filaments stretched over the enormous cosmic voids,” he said.
It’s hard to drink that in and then try and imagine, if some sort of super being made it all, it made it for us exclusively. The idea that said super being is keeping a list and checking it twice, to find out who is naughty or nice, or that its terribly concerned with how long our beards are, what we eat on Friday, or who sleeps with who is beyond laughable.
