In 1982, this "graceful exit problem" was solved independently by Andrei Linde and by Andreas Albrecht and Paul J. Steinhardt, [5] who showed how to end inflation without making empty bubbles and, instead, end up with a hot expanding universe. The basic idea was to have a continuous "slow-roll" or slow evolution from false vacuum to true ...
Bust-a-Move Universe, known in Japan as Tobidasu! Puzzle Bobble 3D [a], and in the PAL region as Puzzle Bobble Universe, [2] is a puzzle video game developed by Taito and Arika and published by Square Enix for the Nintendo 3DS. It was released in Japan as a launch title on February 26, 2011, and was released in North America on March 27.
The inflaton field is a hypothetical scalar field which is conjectured to have driven cosmic inflation in the very early universe. [1] [2] [3] The field, originally postulated by Alan Guth, [1] provides a mechanism by which a period of rapid expansion from 10 −35 to 10 −34 seconds after the initial expansion can be generated, forming a universe not inconsistent with observed spatial ...
The Southern Ring Nebula is a dying star that has imploded and is slowly expelling the layers of its atmosphere in successive waves, creating ever-expanding bubbles of colorful gas. Scientists ...
The expansion of the universe can be understood as resulting from an initial condition in which the contents of the universe are flying apart. The mutual gravitational attraction of the matter and radiation within the universe gradually slows this expansion over time, but their density is too low to prevent continued expansion. [20]
The accelerated expansion of the universe is thought to have begun since the universe entered its dark-energy-dominated era roughly 5 billion years ago. [ 8 ] [ notes 1 ] Within the framework of general relativity , an accelerated expansion can be accounted for by a positive value of the cosmological constant Λ , equivalent to the presence of ...
Two years of data from NASA's James Webb Space Telescope have now validated the Hubble Space Telescope's earlier finding that the rate of the universe's expansion is faster - by about 8% - than ...
In physical cosmology, cosmic inflation, cosmological inflation, or just inflation, is a theory of exponential expansion of space in the very early universe.Following the inflationary period, the universe continued to expand, but at a slower rate.
