Физика (перечитывая Quanta Magazine)
Jan. 1st, 2023 11:46 pmНашёл очень прилично выглядящую теорию, объясняющую "космологическую константу" ("темную энергию", наблюдаемое ускорение разбегания галактик).
Ещё нашёл статью, где, в частности, говорится
"A crucial lesson learned from the first [...] of LHC data is that hadron colliders are not only discovery machines but also excellent precision machines. This result could not have been anticipated at the time the LHC started and was possible only because of the successful interplay between different elements: unprecedented technological advancements, exceptional accelerator performances, excellent detector resolutions, high-performance computing and data handling, higher-order theoretical calculations of background processes with accuracies unthinkable only a few years ago. The confluence of different expertise from different scientific communities was the secret behind the success of the LHC precision programme, which brought new knowledge and opened new prospects in research beyond traditional frontiers. Precision has become key for present and future exploration in high-energy physics."
И, помимо этого замечательного прогресса в точности экспериментов, в той же статье:
"There are also theoretical indications for questioning the concept of symmetry. ... Gauge symmetries may not be as fundamental as we thought, but only an emergent phenomenon. They could be a mirage of a different reality that takes place at a more fundamental level. Maybe the LHC is telling us that it is not just a matter of adapting our models or adjusting some parameters, but it is really time to look for radically different paradigms."
Детали и ссылки, как обычно, в комментариях.
