Using Telescopes to Synthesize the Earth's Size

Time is everything for what we do. We have to be extremely accurate because any ship in time between signals means that we're no longer in the reference frame of the black hole. So it all has to be exactly aligned at the same time. And then we also go through a very lengthy data processing step in which we correct all the additional effects. The telescope is not physically the size of the earth, but we synthesize it using telescopes that span thesize of the earth.
