Nooone asked: The diameter of the Hubble Space Telescope is 2.4 meters; the diameter of the new Chilean telescope is 9.6 meters.
How many times better is the theoretical resolution of the new Chilean telescope (the best possible resolution that the Chilean telescope could achieve if nothing else outside of the telescope itself acted to make the resolution worse) compared to the theoretical resolution of the Hubble Space Telescope? Again, show your work or explain your reasoning.

raul asked: of 8mm, how many photons per second could newton detect with the telescope compared to without? Assume 100% reflectivity of the mirror and that he just used one eye. I squared 33 and 8 and subtracted them from each other. The choices are 8, 17, 33, 38, 1089. I believe it is 1089. Any confirmation?

*titi* asked: In 2015, the California 30-m telescope will have 500 segments acting as one mirror and stand as tall as a six story apartment; the segmeented mirror of the European Extremely Large Telescope will be 42m in diameter and be as large as an olympic swimming pool. How many times fastes is the European telescope than the Californian? Show work please.

Gareth asked: Basically, is it because the wider the telescope. The higher amount of electromagnetic waves can be absorbed, reflected or refracted by the telescope itself?

Loose Change™¢ asked:
If you turned the telescope around 180 degrees in the opposite direction and found another quasar 12 billion LY distant, wouldn’t that mean our *visible* universe is at least 24 billion LY in diameter? Wouldn’t the distance from quasar1 to quasar2 be 24 billion LY?
