![]() ![]() I noted that it is not a problem for this group of scientists that the standard Einstein/Newtonian–inflation–plus–dark-matter–plus–dark-energy (the LCDM) model (I include here warm and fuzzy dark matter versions as these are extremely similar to the cold-dark matter version) does not conserve energy. I have been at a few such conferences ( DMC Nr.77). It keeps many bright people busy and some at a very elevated state of fame: “We have discovered a major new mystery of the Universe and only the very brightest of minds will be able to solve it.” Such minds can only be found in Ivy League Universities. This Hubble Tension is keeping hundreds if not thousands of astronomers and physicists busy in their jet-setting around the world to meet at repeating conferences at which the latest ideas on exotically complex, time or space-dependent dark energy descriptions are announced as possible solutions to the Hubble Tension. Global expansion is obtained by fitting the standard cosmological model to the cosmic microwave background ( CMB) properties. Local expansion is obtained by using standard candles, the type Ia supernovae that explode in galaxies, by associating their distances to their recessional speeds. It seems that experts have a conference once a month somewhere on the globe to discuss why the local Universe seems to be expanding faster than the global Universe. The press release from the University of Bonn on this matter can be read here (and from Charles University in Prague here) and a description can also be found in The Conversation. Moritz Haslbauer is a finishing PhD student at the University of Bonn who has been contributing to The Dark Matter Crisis (DMC). Sergij Mazurenko is an undergraduate physics student at the University of Bonn, and Indranil Banik was an Alexander-von-Humboldt Fellow with us until recently and is currently at the University of St. This post is based on the research paper by Mazurenko, Banik, Kroupa & Haslbauer (2023, MNRAS). But not in the Einstein/Newtonian Lambda-cold-dark-matter model ![]()
