Maybe we’ll live long enough to see the completion of either solar gravitational lensing telescope or earth atmospheric lensing one. Either will (theoretically) let us imagine the surface features on extrasolar planets.
- ravel-bar-foo 4y agoWhat is the focal distance of solar gravitational lensing?
