There are models of two related universes that e.g. attempt to explain the baryon asymmetry – why there was more matter than antimatter at the beginning – with a mirror anti-universe. [78] [79] [80] One two-universe cosmological model could explain the Hubble constant (H 0) tension via interactions between the two worlds. The "mirror world ...
More Than One Universe: The Collected Stories of Arthur C. Clarke is a collection of science fiction short stories by Arthur C. Clarke originally published in 1991.. The stories originally appeared in the periodicals Playboy, Vogue, Dude, New Worlds, The Magazine of Fantasy & Science Fiction, Dundee Sunday Telegraph, Analog, Amazing Stories, Galaxy Science Fiction, Infinity Science Fiction ...
But second, "as a last resort", humans can convert these predictions into explanations by assuming that there is more than one universe, in fact a large and possibly infinite collection of universes, something that is now called the multiverse ("world ensemble" was Carter's term), in which the parameters (and perhaps the laws of physics) vary ...
One of the oldest stars with a multiplanetary system, although it is still more metal-rich than the Sun. None of the known planets is in the habitable zone. [30] 61 Virginis: Virgo: 13 h 18 m 24.31 s: −18° 18′ 40.3″ 4.74: 28: G5V: 0.954: 5531: 8.96: 2 (1) Planet d remains unconfirmed, [31] and a 2021 study found that it was likely a ...
1989 – Margaret Geller and John Huchra discover the "Great Wall", a sheet of galaxies more than 500 million light years long and 200 million wide, but only 15 million light years thick. 1990 – Michael Rowan-Robinson and Tom Broadhurst discover that the IRAS galaxy IRAS F10214+4724 is the brightest known object in the Universe.
All is fair in the Dick Wolf universe, including character crossovers and actors popping up on more than one series at a time. After getting his start as a writer on Hill Street Blues in 1985 ...
The quantum-mechanical "Schrödinger's cat" paradox according to the many-worlds interpretation.In this interpretation, every quantum event is a branch point; the cat is both alive and dead, even before the box is opened, but the "alive" and "dead" cats are in different branches of the multiverse, both of which are equally real, but which do not interact with each other.
Speculative theories with more than one time dimension have been explored in physics. The additional dimensions may be similar to conventional time, [1] compactified like the additional spatial dimensions in string theory, [2] or components of a complex time (sometimes referred to as kime). [3]
