The telescopes of the Event Horizon Telescope were all within an Earth diameter of each other. There's nothing but a bit of money stopping us from doing the same trick with multiple telescopes dispersed around the Sun, say, around the Earth's orbital path. That would increase the resolution by the ratio of 1 AU to Earth's radius, a factor of over 20,000.
