We now perceive the dawn of a whole new reign of cosmic development—an era of opportunity for advanced life forms to begin truly to unlock secrets of the Universe, to fathom our role in the cosmos, indeed to decipher who we are and whence we came. We have become smart enough to reflect back upon the material contents that gave us life, and the result is a rich natural history unparalleled in human knowledge.

“Figure 2: Energy rate density, Φ m, for a wide spectrum of systems observed throughout Nature displays a clear increase across ~14 billion years, implying rising complexity throughout all known historical time. The solid blue curve in this “master plot,” graphed on the same temporal scale as in Figure 1, implies an exponential rise as cultural evolution (steepest slope at upper right) acts faster than biological evolution (moderate slope in middle part of curve), which in turn surpasses physical evolution (smallest slope at lower left). The shaded area includes a huge ensemble of Φ m values as many different individual types of complex systems continued changing and complexifying since their origin; the several small dashed blue lines within that shaded area delineate some major evolutionary events that are then graphed in greater detail in Figures 3–9. The Φ m values and historical dates plotted here are estimates for specific systems on the evolutionary path that led to humankind, namely, the Galaxy, Sun, and Earth, as well as much life all across our planet. As such, this particular graph is of the greatest relevance to big historians seeking to understand how human society emerged naturally over the course of all time.” —Eric J. Chaisson, The Natural Science Underlying Big History, The Scientific World Journal, Volume 2014 (2014)
Nothing in Nature is black or white, few solutions are clean and clear rather, reality, and especially our models of it, possess shades of gray throughout.

The two go hand in hand like a dance: chance flirts with necessity, randomness with determinism. To be sure, it is from this interchange that novelty and creativity arise in Nature, thereby yielding unique forms and novel structures.

Researchers argue that it's of utmost importance to unravel the nature of black holes, lest we someday begin to worship them. Sounds ridiculous, but whole segments of humankind have often revered the unknowable, venerating that which cannot be tested experimentally. Come to think of it, many still do in twenty-first-century society.

Earth is neither central nor special; we inhabit no unique place in the universe.
