The hot disk of gas around black hole M87 is a whopping 55 million light years from Earth, and therefore has a tiny angular size in the sky: only 2.00 x 1078 degrees. Based on the Rayleigh criterion, what is the minimum diameter (in m) of a circular telescope aperture that would be needed to resolve this object using microwaves with a wavelength of 1 mm? Remember to convert degrees to radians first (multiply by 7/180). Give your final answer to three significant digits
