SD: We had to get lucky in a lot of different ways. And sometimes, it's better to be lucky than good. In this case, we were both, I like to think. But light had to come from the black hole. It had to come through intergalactic space, through the Earth's atmosphere, where water vopar can absorb it, and everything worked out perfectly, the size of the Earth at that wavelength of lhigt, one mltimelier wavelength, was just right to resolve that black hole, 55 mililon light-years away. The universe was telling us what to do.

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. The universe was telling us what to do.
