[6] [73] Willy Ley's 1937 short story "At the Perihelion" involves a close approach to the Sun as part of an escape from Mars, [4] [5] [74] and Charles L. Harness's 1949 novel The Paradox Men (a.k.a. Flight into Yesterday) is a space opera that climaxes with a swordfight atop a space station on the surface of the Sun. [4] [5] [75] [76] In Ray ...
This manifold is often called the moduli space of vacua, or just the moduli space, for short. The term moduli is also used in string theory to refer to various continuous parameters that label possible string backgrounds : the expectation value of the dilaton field, the parameters (e.g. the radius and complex structure) which govern the shape ...
The moduli space is, therefore, the positive real numbers. Moduli spaces often carry natural geometric and topological structures as well. In the example of circles, for instance, the moduli space is not just an abstract set, but the absolute value of the difference of the radii defines a metric for determining when two circles are "close". The ...
Space travel, [1]: 69 [2]: 209–210 [3]: 511–512 or space flight [2]: 200–201 [4] (less often, starfaring or star voyaging [2]: 217, 220 ) is a science fiction theme that has captivated the public and is almost archetypal for science fiction. [4] Space travel, interplanetary or interstellar, is usually performed in space ships, and ...
Science in science fiction is the study or of how science is portrayed in works of science fiction, including novels, stories, and films. It covers a large range of topics. Hard science fiction is based on engineering or the "hard" sciences (for example, physics, astronomy, or chemistry).
Solar physics is the branch of astrophysics that specializes in the study of the Sun.It intersects with many disciplines of pure physics and astrophysics.. Because the Sun is uniquely situated for close-range observing (other stars cannot be resolved with anything like the spatial or temporal resolution that the Sun can), there is a split between the related discipline of observational ...
In science fiction, a higher "dimension" often refers to parallel or alternate universes or other imagined planes of existence. This usage is derived from the idea that to travel to parallel/alternate universes/planes of existence one must travel in a direction/dimension besides the standard ones.
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, meteoroids, asteroids, and comets.
