1 The Universe is 13.82 billion years old. 2  The Universe is expanding a bit slower than we expected. 3  The Universe is 4.9 percent normal matter, 26.8 percent dark matter, and 68.3 percent dark energy.  The Universe is lopsided. Just a bit, just a hint, but that has profound implications.
So if the Universe is now 13.7 billion years old, light can only have traveled a distance of 13.7 billion light-years since the beginning of time. Thus, the part of the Universe we can observe (the Visible Universe) lies within a sphere with a radius of 13.7 billion light years centered around the Earth. We can only observe 13.7 billion light years of the Universe. [2.10a] Down the Rabbit Hole: Olbers' Paradox.
