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.
For instance, from the early 1960s until the early 1990s, the age of the universe was estimated to be 16â18 billion years. Notice that the range in this age estimate does not overlap with the current range of age estimate. The gap between the two ranges 2 billion years.
