The birth of the first stars represents the beginning of a sequence that produced all the worlds and living beings of the universe. Simulations can be used to study the critical first steps that telescopes cannot yet see.
“Doubtless any form of criminal obscenity statute applicable to a bookseller will induce some tendency to self-censorship and have some inhibitory effect on the dissemination of material not obscene, but we consider today only one which goes to the extent of eliminating all mental elements from ...

The total sea-level-equivalent (SLE) mass loss after 5,000 years is 10.4 m, close to the 11.3 m simulated by a previous study that used ice-shelf hydrofracture and marine ice-cliff instability20, neither of which are used here. Extended Data Fig. 4 Committed response of West Antarctica....
Their emergence signalled the end of the cosmic dark ages, a few hundred million years after the Big Bang, leading to a fundamental transformation of the early Universe through the production of ionizing photons and the initial enrichment with heavy chemical elements. We here review the state of...
