Why are telescopes built?

[glassnumbers]

Hey guys, don't feel too terrible, you've convinced me, at least. If its more ecofriendly and works better, the only reason not to support the TMT is fear or ignorance or both. The reason being that the older telescopes have more chance to cause environmental problems, so its just a no brainer to put double-hulled ones up there instead of the older models. Honestly, from that perspective, which is ...true, the older models, do, in fact, have a much greater chance of leaking...They should replace ALL of the old telescopes, they shouldn't stop with TMT.
