What does 13.8 billion years of history tell you about yourself? How does knowing so much about the past change the way you think about the future? These may be the most important questions Big History asks. How would you answer them? Big history is an unfinished story.
What ingredients will be important, and what Goldilocks Conditions will make circumstances "just right" for a new level of complexity? Of course, we cannot see the future, but we can study those trends that seem most likely to shape the future.
The remote future
Oddly, it is easier to predict the very remote future, the future of the Earth and the Universe, because at this larger scale change is slower and there are fewer variables to calculate. The Sun will die in about 4 to 5 billion years, swelling until it gobbles up and destroys the Earth.
Evidence from distant galaxies suggests that the Universe's expansion is accelerating, which in turn suggests that galaxies will slowly become more and more isolated until, eventually, all stars burn out. The Universe will then fill up with dying stars, which will get pulled into the enormous gravitational field of black holes. The Universe will become simpler and simpler. This will not occur for billions of years. For now, we are living in the Universe's youth, in which we have abundant energy to generate new, complex, and interesting objects, such as ourselves!
Closer to home
At present, we can see both dangerous trends, such as global warming and the continued existence of nuclear weapons, as well as positive trends, such as increased collaboration in dealing with climate change, a slowing in population growth, and an acceleration in our knowledge about the biosphere.
Can we imagine a future largely free of conflict, disease, and degradation, one in which some humans may even begin to migrate to other worlds as our Paleolithic ancestors migrated to other continents? Or are we in danger of undermining the foundations of today's world with vicious conflict over scarce resources? The answers will depend on decisions made by the generations of humans that are alive today.
