Wherever we are in the universe, there exists a cosmic background radiation. No matter how dark it gets, there is a maximum to darkness and a minimum to light in nature. Now, man should be able to play tricks on nature- to produce DARKNESS or LIGHT- that is accentuated. This is what man does- to learn from nature- and take advantage of what it does.

I don't know why- but I am thinking about black body radiation and Brownian motion right now. I know the telescope- when it operates outside infinity is non-adjustable. Sadly I know our lenses are inadequate. But, physics-wise, our advancement will ALWAYS be precluded by some HUGE experiment.
