Scientific Revolutions: Can an Astronomical Anomaly Challenge Them?

An astronomical anomaly, the Hubble tension, challenges the established understanding of the expansion of the Universe and may lead to a scientific revolution.

The Economist team analyzes how scientific revolutions, such as the Copernican revolution and Lavoisier's discoveries, change our perspective on the world.

Thomas Kuhn's paradigm shift theory argues that these revolutions require a change in how we perceive the components of the world.

The Hubble Space Telescope contributed to determining the Hubble constant, but newer estimates, based on background radiation, are significantly lower, creating the 'Hubble tension'.

This anomaly could trigger a new paradigm shift, although science has shown an ability to adapt to new ideas without complete change.

The Hubble tension proves that paradigms can always change, potentially leading to future scientific revolutions.
