If you're a fan of spooky space pictures like we are here at the Strange Mysteries thunder-volcano headquarters..... A regular old black hole is creepy enough, as these time-bending regions of space allow nothing to escape from their grasp. The only thing scarier than a supermassive black hole is a bunch of black holes screaming across the galaxy at nine-hundred million miles per hour. If you were to try and imagine what something called the Bootes void might look like, you may have to take yourself off for a quick cold shower. Dark Flow is the name scientists have given to the mysterious force which they have detected beyond the borders of our visible universe. Where does space actually start? Is it near where the Dragon capsule is re-entering the atmosphere in the center/left of this image? Is it closer to the ISS, where this picture was taken? Or is it somewhere else entirely? Where’s the edge of space? What seems like a simple question has an answer with more layers than the Earth’s atmosphere. You might expect that space begins where the atmosphere ends, and that could be true. But, as it turns out, no one can tell exactly where that point is. And the majority of scientists look much closer to home, placing the edge of space well within the bounds of the atmosphere.
