30. While admitting that this is beside your point, WMAP data and Planck data nevertheless yielded:

The Universe Is 13.82 Billion Years Old
By Phil Plait

...

The Universe is 13.82 billion years old.

The age of the Universe is a little bit higher than we expected. A few years ago, the WMAP spacecraft looked at the Universe much as Planck has, and for the time got the best determination of the cosmic age: 13.73 +/- 0.12 billion years old.

Planck has found that the Universe is nearly 100 million years older than that: 13.82 billion years.

At first glance you might think this is a really different number. But look again. The uncertainty in the WMAP age is 120 million years. That means the best estimate is 13.73 billion years, but it could easily be 13.85 or 13.61. Anything in that range is essentially indistinguishable in the WMAP data, and 13.73 is just in the middle of that range.

And that range includes 13.82 billion years. Itís at the high end, but thatís not a big deal. Itís completely consistent with the older estimate, but Planckís measurements are considered to be more accurate. It will become the new benchmark for astronomers.
