Description
An intriguing tension in the measurements of the Hubble constant H0, which sets the expansion rate of the Universe, has emerged in recent years. Independent determinations of H0 are important to assess the tension, which if verified, would imply new physics beyond the standard cosmological model. I will illustrate strong gravitational lenses with measured time delays between the multiple images as a way to measure H0. Exciting discoveries of the first strongly lensed supernovae offer new opportunities for measuring H0, and I will present recent advances. I will show the bright prospects of lensed supernovae as an independent and competitive cosmological probe.
