Hubble Constant? The universe may be a billion years younger than we thought

In a March 18 2019 story at NBC, Corey S. Powell reports how some
astronomers, including Nobel laureate Adam Riess of the Space Telescope
Science Institute in Baltimore, are starting to wonder if the universe
might only be 12.5 to 13 billion years old.

Having pegged the Hubble Constant to the point where it was believed
the universe was 13.7990.021 billion old based on many different types
of observations and the Lambda-CDM concordance model, some astronomers
are seeing observations that don't agree with the detailed 2013 Planck
Observatory observations of the cosmic background radiation.

It's an interesting article, thanks Gary. Sometimes it seems that more more we learn the more we realise how much we don't know!

The concept of dark energy is intriguing, makes me think of hidden dimensions influencing each other...
