Would whomever voted to reopen mind adding a comment to explain why?  It seems like the duplicate listed is accurate.

θ = 1.22 (λ/D) where θ is the angular resolution(radians), λ is the wavelength of light and D is the diameter of the lens' aperture.

@user6760 That's the key to the answer, just write it up with some explanation and post it as an answer. Don't forget to explain how the "aperture" is determined for interferometry telescopes and the difficulties in using optical interferometry.

@Donald.McLean I'm afraid my knowledge in this area is limited, I hope you may give some insights on interferometry thanks.

Wikipedia has some good articles that talk about the issues (such as https://en.wikipedia.org/wiki/Astronomical_interferometer ). I think the main things are the incredible precision required and how the number of mirrors involved cause significant attenuation of the signal, severely limiting which objects that can be imaged in this way.

If we built one hundred 3m telescopes and point them to a single star what would be the final resolution?
