the moment of singularity

The popular term for the actual beginning of the Universe has come to be the "big bang", which actually describes the moments afterwards.
The actual moment in time, umpteen Billion years ago, when literally everything in the Universe could fit into an oven is described as the event horizon, or the singularity.
A time when this small superdense object had so much mass, it would bend time like silly putty, so the concept of time is less easily applied. And the math tends to break down around then as well.
This singularity, this beautiful bundle of energy, probably wasn't around for very long, (again, the whole concept of time becomes an illusion) before it exploded more violently than we can imagine.
This is referred to as the expansion, or inflation. When the everything blew apart from itself, and began to grow very big, very quickly. (The math gets buggered up here as well.) This shining sphere of everything blew up much faster than it should have, and it is expanding faster than it should be.
There, as they say, is the rub. We know enough to know that there are unknowns. That even though we have figured out a great deal about how everything works, we still can't explain some very troubling questions about the Universe. Our brains aren't yet sophisticated enough, or some of the equations are flawed, or observation changes outcome more than we thought. We don't know.
That answer is difficult to accept for a species with such an inquisitive brain, so we will continue to search for answers. Contine re-working theories, and developing new ideas. We are aware of our ignorance, and we endeavor to learn.
This gives me hope that people will come to identify with each other as a species, and relate to their fellow man in a way that better reflects our interdependence and our ultimate commonality of purpose.
Then I like to think about the singularity.
