“The Crab Nebula is about 6,500 light years from earth. According to some beliefs, that’s the age of the whole universe. But if the universe were only 6,500 years old, how could we see the light from anything more distant than the Crab Nebula? We couldn’t. …To believe in a universe as young as six or seven thousand years old is to extinguish the light from most of the galaxy. Not to mention the light from all the hundred billion other galaxies in the observable universe.” Neil deGrasse Tyson, Cosmos: A Spacetime Odyssey (Ep. 4: A Sky Full of Ghosts)
