The James Webb Telescope is set to launch in October of 2018 and will allow us to study the formation of first generation stars, the molecular clouds that became the first galaxies, and directly image exoplanets. Roughly one hundred times more powerful than the Hubble Space Telescope the JWST is going to push back the current boundaries of science.
This is what 100-million man hours can accomplish.
The most complex telescope ever built that will allow us to see things never before witnessed and explore parts of our universe previously hidden from view. It will even be able to look at the atmospheres of distant exoplanets and detect the chemical traces of life - if it's to be found. This is what time well spent looks like.
Conversely, the JWs spent over eighty times that many hours preaching. And what do they have to show for their efforts? Stagnant growth? No widows or orphans that they've taken care of? Even more broken families? Not even one single charity event they can point to?
Which bears better fruit - the assertions of religious dogma - or the disciplined efforts of scientific inquiry?
