The Hubble Tension with Prof Geraint Lewis (174)
Shirtloads of Science - En podcast af Dr Karl Kruszelnicki - Søndage
The Hubble Space Telescope launched in 1990. It is named after the American astronomer who found our universe was expanding. Ninety years on, with much better kit, Hubble’s ideas still hold. The question is how fast are we inflating? This is the Hubble tension and Prof Geraint Lewis leads Dr Karl through the deep space discussion. http://www.physics.usyd.edu.au/~gfl/
