Complementary antonyms are word pairs whose meanings are opposite but whose meanings do not lie on a continuous spectrum (push, pull). Relational antonyms are word pairs where opposite makes sense only in the context of the relationship between the two meanings (teacher, pupil). These more restricted meanings may not apply in all scholarly ...
The direction in space that is directly opposite the center of the Milky Way Galaxy, as viewed from Earth; considered as a point on the celestial sphere, the Milky Way's anticenter is in the constellation Auriga. Galactic Center The rotational center of the Milky Way galaxy, consisting of a supermassive black hole of 4.100 ± 0.034 million ...
It assumes that space is Euclidean: it assumes that space follows the geometry of common sense. [2] In the context of special relativity, time cannot be separated from the three dimensions of space, because the observed rate at which time passes for an object depends on the object's velocity relative to the observer.
The commonsense world consists of "time, space, physical interactions, people, and so on". [1] Common sense is "all the knowledge about the world that we take for granted but rarely state out loud". [5] Common sense is "broadly reusable background knowledge that's not specific to a particular subject area... knowledge that you ought to have." [6]
For example, on the International Space Station the Earth's gravity is nearly 90% as strong as at the surface. Objects orbiting in space would not remain in orbit if not for the gravitational force, and gravitational fields extend even into the depths of intergalactic space.

Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the Timaeus of Plato, or Socrates in his reflections on what the Greeks called khôra (i.e. "space"), or in the Physics of Aristotle (Book IV, Delta) in the definition of topos (i.e. place), or in the later "geometrical conception of place" as "space qua extension" in the ...
A physical body is an enduring object that exists throughout a particular trajectory of space and orientation over a particular duration of time, and which is located in the world of physical space (i.e., as studied by physics). This contrasts with abstract objects such as mathematical objects which do not exist at any particular time or place.
The common sense is where this comparison happens, and this must occur by comparing impressions (or symbols or markers; σημεῖον, sēmeîon, 'sign, mark') of what the specialist senses have perceived. [16] The common sense is therefore also where a type of consciousness originates, "for it makes us aware of having sensations at all". And ...
