So say the people behind the Giant Magellan Telescope, and what a giant it will be. I was fortunate to be at the ANU in Canberra for a briefing/introduction to the GMT last Monday by some of the scientists and engineers working on the enormous behemoth and the instrumentation for it.
If you haven't looked into it, it will have 7 mirrors 8.4 metres in diameter, weighing about 22 tonnes each, bouncing light up to 7 secondaries about a metre each which are only a few millimetres thick and deformable (AO)
Aperture at maximum : 24.5 metres
