Concepts of time and space play a major role in the Old Norse corpus's presentation of Norse cosmology. While events in Norse mythology describe a somewhat linear progression, various scholars in ancient Germanic studies note that Old Norse texts may imply or directly describe a fundamental belief in cyclic time.
An inhomogeneous cosmology is a physical cosmological theory (an astronomical model of the physical universe's origin and evolution) which, unlike the dominant cosmological concordance model, assumes that inhomogeneities in the distribution of matter across the universe affect local gravitational forces (i.e., at the galactic level) enough to skew our view of the Universe.

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]
To an extent, all theories about mythology follow a comparative approach—as scholar of religion Robert Segal notes, "by definition, all theorists seek similarities among myths". [3] However, scholars of mythology can be roughly divided into particularists, who emphasize the differences between myths, and comparativists, who emphasize the ...
In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events ...
Philosophy of space and time is the branch of philosophy concerned with the issues surrounding the ontology and epistemology of space and time. While such ideas have been central to philosophy from its inception, the philosophy of space and time was both an inspiration for and a central aspect of early analytic philosophy. The subject focuses ...
Chris Hemsworth gives a godly performance as a superhero looking for new purpose in the midst of his franchise’s struggle to do the same.
1905 – Albert Einstein publishes the Special Theory of Relativity, positing that space and time are not separate continua, and demonstrating that mass and energy are interchangeable. 1912 – Henrietta Leavitt discovers the period-luminosity law for Cepheid variable stars, which becomes a crucial step in measuring distances to other galaxies.
