Posted by in category: cosmology

The latest measurement of the expansion rate of the Universe is in, and it has confirmed with more certainty than ever that we have a real dilly of a pickle on our hands. Once again, the result has shown that the Universe is expanding much faster than it should be based on the conditions just after the Big Bang.

The Universe’s rate of expansion is called the Hubble Constant, and it’s been incredibly tricky to pin down.

According to data from the Planck satellite that measured the cosmic microwave background (the conditions of the early Universe just 380,000 years after the Big Bang, the Hubble Constant should be 67.4 kilometres (41.9 miles) per second per megaparsec, with less than 1 percent uncertainty.
