english: It had to come through intergalactic space, through the Earth's atmosphere, where water vapor can absorb it, and everything worked out perfectly, the size of the Earth at that wavelength of light, one millimeter wavelength, was just right to resolve that black hole, 55 million light-years away.
non_english: Svetlost je morala da stiže kroz intergalaktički prostor, kroz Zemljinu atmosferu, gde su vodena isparavanja mogla da je apsorbuju, i sve se savršeno poklopilo, veličina Zemlje na toj talasnoj dužini svetlosti od jednog milimetra bila je odgovarajuća da otkrije crnu rupu udaljenu 55 miliona svetlosnih godina.
