A serious look at the science behind the @GreenLantern

That phenomenon is commonly known as the Big Bang, but it might have been not be what people think, Hammergren continued, "The Big Bang is commonly pictured as a tremendous explosion in space, with matter flying outwards and expanding away from each other. A natural thought is to follow the expansion backwards to find the center of the universe. This is based on an incorrect assumption. Matter and energy did not fly out into preexisting space; space itself came into existence in the Big Bang, and has been expanding since then. So there is no real 'center,' even if the expansion of space conspires to create this illusion. No matter which galaxy you live in, you will see the other galaxies moving away from you, which makes it appear that you are the center of this motion."
