The phrase "an external space" is correct and usable in written English.
It can be used to refer to a space that is outside of a particular area or context, often in discussions about architecture, design, or abstract concepts.
Example: "The architect designed the building to seamlessly connect with an external space, allowing for natural light and ventilation."
Alternatives: "an outside area" or "a foreign environment".
How do successful verbal improvisers manage without shifting some of their workload into an external space?
This phenomenon, known as sequence compression (Skaggs et al., 1996; Dragoi and Buzsaki, 2006) is thought to be an animal model of the internal representation of an external space by the place cell assemblies in the CA1 area of the rodent hippocampus (Skaggs et al., 1996; Dragoi et al., 2003; Dragoi and Buzsaki, 2006; O'Keefe and Nadel, 1978).
It is surrounded in turn by an infinite external space empty of all bodies.
A Minkowski external space emerges only for a special ratio between these two integers, and it is therefore (topologically) isolated from the nearby dS solutions.
In contrast, when protons are pumped into a confined external space, as, for instance, in biofilms [ 132], [ H+] out would increase.
The second possible mechanism, which is the hypothesis we propose here, is that ownership of a different-sized body causes a rescaling of external space, which, in turn, causes target objects in this space to be rescaled accordingly.
These results suggest that the own-body-size effect depends on a rescaling of external space that lasts for at least 5 6 s after the body is no longer visible.
Thus, the own-body-size effect in Experiment 2 can be attributed only to a rescaling of external space to body size that is caused by body ownership and in which new objects are rescaled accordingly without the need for a visible body.
While observing scouting photos of Cape Town, the filmmakers noticed a large three-walled external space that looked like an interior when filmed at night.
Convolution with HRTFs simulates the pinna filter functions and in normal listeners generates a percept of a sound source associated with a particular position in external space; sequential dynamic updating of HRTFs across different spatial positions simulates the perceptual effect of a moving sound source (Warren et al., 2002).
A neural representation of external space at this early time points to strong innate components for perception of space.
