Why again do we not make and utilize the largest, most effective telescope we can possibly make with what technology and materials are available to us ? Like if the the extremely large telescope is land based, and is amazing because it is so large and effective, why are we setting the bar there?  If its a 39 meter diameter mirror, why do we not make a 100 meters in diameter mirror. ?<br>Or why even stop at that is what I'm saying.  Unless there is some kind of physics based limitation, I think we should aim for getting as close to that physics based limitation as we can.<br>If we CAN be taking a better look,<br>Why aren't we?
