  2. Space - Wikipedia

    en.wikipedia.org/wiki/Space

    Space. Space is a three-dimensional continuum containing positions and directions. [1] In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. [2]

  3. Outer space - Wikipedia

    en.wikipedia.org/wiki/Outer_space

    Outer space (or simply space) is the expanse beyond celestial bodies and their atmospheres. It contains ultra-low levels of particle densities, constituting a near-perfect vacuum [1] of predominantly hydrogen and helium plasma, permeated by electromagnetic radiation, cosmic rays, neutrinos, magnetic fields and dust.

  4. Space (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Space_(mathematics)

    Space (mathematics) In mathematics, a space is a set (sometimes known as a universe) with a definition ( structure) of relationships among the elements of the set. While modern mathematics uses many types of spaces, such as Euclidean spaces, linear spaces, topological spaces, Hilbert spaces, or probability spaces, it does not define the notion ...

  5. Space exploration - Wikipedia

    en.wikipedia.org/wiki/Space_exploration

    Space exploration also gives scientists the ability to perform experiments in other settings and expand humanity's knowledge. Another claim is that space exploration is a necessity to mankind and that staying on Earth will lead to extinction. Some of the reasons are lack of natural resources, comets, nuclear war, and worldwide epidemic.

  6. Non-breaking space - Wikipedia

    en.wikipedia.org/wiki/Non-breaking_space

    Non-breaking space. In word processing and digital typesetting, a non-breaking space ( ), also called NBSP, required space, [1] hard space, or fixed space (in most typefaces, it is not of fixed width ), is a space character that prevents an automatic line break at its position. In some formats, including HTML, it also prevents consecutive ...

  9. Spacetime - Wikipedia

    en.wikipedia.org/wiki/Spacetime

    t. e. In physics, spacetime 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 occur.
