3 mag 2024 · The chronology of the universe describes the history and future of the universe according to Big Bang cosmology. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.
3 giorni fa · The Lambda-CDM, Lambda cold dark matter, or ΛCDM model is a mathematical model of the Big Bang theory with three major components: a cosmological constant denoted by lambda (Λ) associated with dark energy. the postulated cold dark matter denoted by CDM. ordinary matter.
3 mag 2024 · The Big Bang model states that the earliest state of the universe was an extremely hot and dense one, and that the universe subsequently expanded and cooled. The model is based on general relativity and on simplifying assumptions such as the homogeneity and isotropy of space.

1 mag 2024 · The scientific story behind the timeline of our Universe. From the earliest stages of the hot Big Bang (and even before) to our dark energy-dominated present, how and when did the Universe grow...
Poche serie sono riuscite ad avere l’impatto culturale che ha avuto “The Big Bang Theory” negli ultimi anni in tutto il mondo, Italia compresa. La serie è riuscita infatti non solo ad entrare con forza nella cultura di massa ma, per certi versi, è riuscita a creare anche una sorta di “sub-cultura”, grazie ai suoi sketch e ai suoi tormentoni entrati ormai nel vocabolario e nelle ...
1 giorno fa · Two of the greatest successes of the Big Bang theory are its prediction of the almost perfect black body spectrum and its detailed prediction of the anisotropies in the cosmic microwave background. The CMB spectrum has become the most precisely measured black body spectrum in nature.
3 giorni fa · In physical cosmology, cosmic inflation, cosmological inflation, or just inflation, is a theory of exponential expansion of space in the early universe. The inflationary epoch is believed to have lasted from 10 −36 seconds to between 10 −33 and 10 −32 seconds after the Big Bang.
