Hi,
I recently read about the exciting research and progress being made with lenses made from negative refractive index materials. In theory, these materials have no limit to their resolving power and so far experiments have shown they can image objects smaller than that possible using conventional optical microscopes.
It made me wonder whether the same would be true for telescopes. Whatever the engineering challenge, surely we can hope that one day telescopes could exist that can image tiny objects in the sky from distant asteroids to rivers on exoplanets to the earliest star systems in the Universe... are these almost fantastical telescopes feasible?
