If the supermassive black hole that was knocked out of its galaxy recently was 8 billion light years away then how could it have happened 1-2 billion years ago? This was listed on multiple articles but the main article in reference is: http://www.spacetelescope.org/news/helc1706/
The only 2 conclusions that I can come up with are that a)the information was wrong or b)our galaxy is moving directly away from the light coming from the debris outside the event horizon of the supermassive black hole in question.... which i'm no mathmatician but light travels about 670,616,629 mph and our galaxy travels at about 515,000 mph which doesent seem to add up. Could someone please help explain this to me?
