Multiple independent timeframes, in which time passes at different rates, have long been a feature of stories. [15] Fantasy writers such as J. R. R. Tolkien and C. S. Lewis have made use of these and other multiple time dimensions, such as those proposed by Dunne, in some of their most well-known stories. [15]
[6] [7] [8] The current version of The Scale of the Universe 2 uses Pixi.js instead of Flash, ported by Matthew Martori. [6] The Scale of the Universe was featured on NASA's Astronomy Picture of the Day on October 7, 2018. [9] In 2020, animation studio Kurzgesagt released the app Universe in a Nutshell, which took inspiration from The Scale of ...
The phenomenon of dimensional reduction has now been reported in a number of different approaches to quantum gravity. String theory, [2] causal dynamical triangulations, [3] renormalization group approaches, [4] noncommutative geometry, [5] loop quantum gravity [6] and Horava-Lifshitz gravity [7] all find that the dimensionality of spacetime appears to decrease from approximately 4 on large ...
According to the theory of cosmic inflation initially introduced by Alan Guth and D. Kazanas, [23] if it is assumed that inflation began about 10 −37 seconds after the Big Bang and that the pre-inflation size of the universe was approximately equal to the speed of light times its age, that would suggest that at present the entire universe's ...
Then the number of dimensions may have increased as the system cooled and the Universe may gain more dimensions with time. There could have originally been only one spatial dimension, with two dimensions total — one time dimension and one space dimension. [1] When there were only two dimensions, the Universe lacked gravitational degrees of ...
In 1998/99, Merab Gogberashvili published on arXiv a number of articles where he showed that if the Universe is considered as a thin shell (a mathematical synonym for "brane") expanding in 5-dimensional space then there is a possibility to obtain one scale for particle theory corresponding to the 5-dimensional cosmological constant and Universe ...
The fractal dimension of a homogeneous 3D object would be 3, and 2 for a homogeneous surface, whilst the fractal dimension for a fractal surface is between 2 and 3. The universe has been observed to be homogeneous and isotropic (i.e. is smoothly distributed) at very large scales, as is expected in a standard Big Bang or Friedmann-Lemaître ...
However, for string theory to be mathematically consistent, the strings must live in a universe with ten dimensions. String theory explains our perception of the universe to have four dimensions (three space dimensions and one time dimension) by imagining that the extra six dimensions are "curled up", to be so small that they can't be observed ...
