    The Big Picture:  What We Know About How the Universe Began and What We Are Trying to Find Out

    Today the Universe is made out of dark matter, dark energy and a small amount of ordinary matter (the atoms we are made of).  We can trace the history of the Universe back to when it was a microsecond and was a formless quark soup.  We now have good evidence for an early burst of tremendous expansion (inflation) that stretched sub-atomic quantum fluctuations to astrophysical size and created the seeds for galaxies.  But there is much to figure out, including what dark matter is made of, what the nature of the mysterious dark energy is, and when inflation took place.
