That telescope will be groundbreaking, even when they decided to make "just" 39m in diameter mirror instead of overly huge 100m mirror. That 100 meter
mirror would have been so awesome, but it was maybe too large to make. But 39 meters will do fine, its still largest mirror on Earth.
The 100 meter version would have gathered more light than every telescope on Earth combined (yes, every). It would have seen 1 500 times fainter
objects than Hubble, even apparent magnitude 38 objects. It was apparently too expensive (1,5 billion dollars) to build and there isn't technology to
operate 100 meter mirror.
