About :

The universe is not unchanging - for almost a hundred years we have known that galaxies are moving away from each other due to the expansion of space. However, we have difficulty accurately estimating the rate of this expansion, expressed using the so-called Hubble constant. We know many methods of observationally determining its value, which, thanks to decades of hard work, are becoming increasingly accurate. However, it turns out that depending on the method, cosmologists receive two significantly different values ​​of the Hubble constant. What consequences does this discrepancy have for physics and our understanding of the cosmos? Is there a serious error lurking in the observational methods, or are we perhaps on the verge of a fundamental revolution in cosmology? Dr. Hab. Sebastian Szybka will talk about all this in his lecture. Dr. Hab. Sebastian Szybka is an astrophysicist and cosmologist, working at the Astronomical Observatory of the Jagiellonian University. He is a collaborator of the Copernicus Centre.
