(if we were far enough from the earth, could we see the dinosaurs)
One comment claimed that the lens would be the limiting factor. If using traditional glass lens, they calculated that it would need a diameter of 4 light years to be able to see the dinosaurs. They furthermore claimed that a lens of this size would gravitationally collapse, and thus would not be feasible.
I don't believe gravitational lensing was mentioned as of my reading.
