23 hours ago · The trio recently published a paper in the Journal of High Energy Physics in which, Ling said, “we mathematically showed that there might be a way to see beyond our universe.”. Working together with Jerome Quintin and Eric Ling, Ghazal Geshnizjani of the Perimeter Institute examined ways in which space-time might be extended beyond the Big ...
2 days ago · t. e. 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.
1 day ago · The Genesis of the Universe. According to the Big Bang Theory, the universe started as a singularity — a point of infinite density and temperature. In an event known as the Big Bang, this singularity began to expand rapidly. The initial expansion happened in a fraction of a second, leading to the creation of space, time, and all the matter ...
1 day ago · The James Webb Space Telescope has detected the two earliest, most distant galaxies in the known universe, dating to just 300 million years after the Big Bang. The detection of even earlier ...
4 days ago · 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 day ago · This record-breaking galaxy existed some 290 million years after the Big Bang. For perspective, this was when the universe was only two percent of its current age of 13.8 billion years old.
1 day ago · It was composed of hydrogen and helium created shortly after the Big Bang 13.8 Ga (billion years ago) and heavier elements ejected by supernovae. About 4.5 Ga, the nebula began a contraction that may have been triggered by the shock wave from a nearby supernova. A shock wave would have also made the nebula rotate.
