* The universe is older than previously thought. Planck's measurements of the cosmic microwave background (CMB), which is the faint afterglow of the Big Bang, suggest that the universe is 13.77 billion years old, with an uncertainty of 40 million years. This is about 100 million years older than previous estimates.
* The universe is expanding faster than previously thought. Planck's measurements of the CMB also suggest that the universe is expanding at a rate of 67.4 kilometers per second per megaparsec. This is about 5% faster than previous estimates.
* The amount of dark matter in the universe is smaller than previously thought. Planck's measurements of the CMB suggest that dark matter makes up about 26.5% of the universe's total energy budget. This is about 10% less than previous estimates.
* The amount of dark energy in the universe is larger than previously thought. Planck's measurements of the CMB suggest that dark energy makes up about 68.3% of the universe's total energy budget. This is about 15% more than previous estimates.
These discoveries from Planck have led to a number of new questions about the universe. For example, what is the nature of dark matter and dark energy? Why is the universe expanding at an accelerating rate? And how did the universe come into being?
The answers to these questions are still unknown, but they are some of the most important questions in physics today. Planck's discoveries have helped to shed light on these questions, and they have opened up new avenues of research.
In addition to the discoveries listed above, Planck has also provided a wealth of other data about the early universe. This data is helping scientists to better understand the evolution of the universe and the formation of galaxies and stars. Planck is a major scientific achievement, and it has had a profound impact on our understanding of the cosmos.
