just-right

The term “just-right” is used to describe all the finely-tuned features scientists observe in the universe which permit life to exist on Planet Earth. Because Earth has all the features necessary to support life, it is often referred to as the Goldilocks Planet. Referring to the children’s story Goldilocks and the Three Bears, just like Goldilocks found Baby Bear’s porridge, chair and bed “just-right”, Earth has the hundreds of “just-right” features which allow it to support life on the planet.
