New hubble constant
WebAnother problem is related to the Hubble constant (H). To date there are two leading approaches to determining H. One of them is based on measurements of the cosmic microwave background, the other is based on measuring the redshift of distant galaxies and then determining the distances to them by luminosity of variables (Cepheids) and … Web1 dag geleden · This new calibration further amplifies the Hubble tension.
