A region that is devoid of any physical objects, representing an area where nothing occupies the space.
An infinite expanse that extends in all three dimensions—up and down, left and right, forward and backward—serving as the setting in which matter exists and various phenomena occur.
In a mathematical context, it refers to a collection of points or structures that can manifest in multiple dimensions, encompassing both geometric forms and abstract spaces with specific mathematical properties.
A foundational concept in philosophy, denoting an essential framework for understanding the physical world, particularly in relation to time and the nature of existence.
Example:
この無限の空間に漂う永遠の沈黙が私を恐怖に陥れる。
A type of mathematical structure that consists of a set equipped with a topology, allowing for the exploration of concepts such as continuity and convergence within the set.
A multidimensional mathematical space that represents all possible states of a physical system, where each point corresponds to a specific configuration defined by position and momentum coordinates.
The vast, seemingly infinite expanse that exists beyond Earth's atmosphere, encompassing all celestial bodies and phenomena.
The region of space situated beyond the Earth's atmospheric limits, typically defined as starting at an altitude of approximately 30 kilometers, where conventional aircraft cannot operate.
A dimension characterized by a lack of atmosphere and gravity, where various physical laws govern celestial movements and interactions.
Example:
地球は宇宙空間に漂う球体にすぎない。
A digitally created environment that allows users to interact with a simulated world through technology, often experienced through screens or virtual reality devices.
An abstract setting generated by computer systems that can represent real or imagined locations, enabling user navigation and engagement within that space.
An immersive online environment where individuals can communicate, collaborate, and participate in activities, often simulating physical interactions in a non-physical realm.
A three-dimensional representation in a computer-generated setting that blurs the line between reality and the virtual world, often used for gaming, education, or social interaction.
A void or area that is unoccupied and lacks physical substance, often perceived as empty space between objects.
An infinite expanse in three dimensions, encompassing vertical, horizontal, and depth dimensions, where materials exist and events occur.
A fundamental concept in philosophy representing the essential framework of reality, interlinked with time and the arrangement of objects in the universe.
A mathematical construct encompassing different dimensions, ranging from one-dimensional lines and two-dimensional planes to three-dimensional spaces, and even extending to higher dimensional spaces used in various mathematical structures.
