Web27 apr. 2024 · Yet the prediction falls short: When cosmologists observe astronomical objects such as pulsating stars and exploding supernovas, they see a universe that’s expanding faster, with a larger Hubble constant. The discrepancy, known as the Hubble tension, has persisted even as all the measurements have grown more precise.

Web2) Another possible set of universe models consider that because the universe indeed has matter in it, it is really inhomogeneous, so the FLRW models don't apply, they only apply in a dynamical/asymptotic sense. Such models are Swiss-Cheese models and Lemaitre-Tolman-Bondi (LTB), in addition to the G2 class of cosmological models. seminare christian bischoffWeb5 mrt. 2024 · It may have been 13.8 billion years since the Big Bang occurred, but with the expansion of the Universe, there are objects as far away as 46.1 billion light-years whose light is just reaching us.... seminare trinkwasserversorgungWeb12 jun. 2024 · But in reality, not only is that galaxy not moving through the Universe at a relativistically impossible speed, but it's hardly moving at all!
