Space is the ultimate frontier. I think when people historically thought of the frontier, there was where you were living and then there was some edge beyond which no one had explored.
There is no terra incognito left.
The actual state of our knowledge is always provisional and... there must be, beyond what is actually known, immense new regions to discover.
It would be kind of magical if we were just happening to be able to see right to some boundary and then something crazy happened beyond that, like galaxies ceased to exist. I mean, that just seems nuts.
The brain is a world consisting of a number of unexplored continents and great stretches of unknown territory.
Besides the pleasure derived from acquired knowledge, there lurks in the mind of man, and tinged with a shade of sadness, an unsatisfactory longing for something beyond the present, a striving towards regions yet unknown and unopened.
The most promising words ever written on the maps of human knowledge are terra incognita, unknown territory.
The full area of ignorance is not mapped. We are at present only exploring the fringes.
I will frankly tell you that my experience in prolonged scientific investigations convinces me that a belief in God-a God who is behind and within the chaos of vanishing points of human knowledge-adds a wonderful stimulus to the man who attempts to penetrate into the regions of the unknown.
I have always loved the wild places between the Sierra Nevada range and the Rocky Mountains. The east face of the Sierra Nevada is steep and largely unknown, a wonderful setting.
Even if all life on our planet is destroyed, there must be other life somewhere which we know nothing of. It is impossible that ours is the only world; there must be world after world unseen by us, in some region or dimension that we simply do not perceive. Even though I can't prove that, even though it isn't logical - I believe it.
Trips to fairly unknown regions should be made twice; once to make mistakes and once to correct them.
And despite the fact that the basis of this mathematical way of thinking in art is in reason, its dynamic content is able to launch us on astral flights which soar into unknown and still uncharted regions of the imagination.
