Is it possible to build an optical telescope that could give you clear images of exoplanets?

Is it a limitation of how big you can build the telescope or a more fundamental limit of light?

This would require interferometry on a massive scale that we don't yet have the technology to implement (but it's not impossible). To see in the the optical band with 1000 km resolution from 100 lightyears away (just spitballing parameters here), you'd need a telescope about 5000 km wide. This is not feasible, but an array of telescopes could do the job (the Very Long Baseline Array already does this for radio astronomy). This array of telescopes could either span the surface of the Earth (while being close enough to point at the same thing), or could be in space.
