What does space mean 20, what does space mean?

1.Explanation of classical physics: The part of the universe outside of the physical entity is called space.

2.Explanation of Relative Physics: The part of the universe where the movement of material entities takes place is called space.

3.Space terminology: Outer space is abbreviated as space, outer space or space.

4.Mathematical term: Space refers to a set of special properties and some additional structure.

5.On the Internet: Refers to a place where documents or logs are kept.

In my opinion, space is an anti-object volume of a pure vacuum.

In my personal opinion, the first meaning of volume and volume is as follows: the size of an object is the volume; The size of the space is the volume.

If volume is to be defined as "the size of the space occupied by an object", then volume can be defined as "the size of the object occupied by space". Volume and volume are relative positives and negatives.

For this purpose, I define volume and volume as follows:The size of an object surrounded by space is called the volume; The size of a space surrounded by objects, and the number of cubic meters contained in it is called volume.

"space" refers to non-objects (anti-objects); "Space" refers to volume (antivolume); "Space" refers to the negative of the geometry (negative three-dimensional).

In general, the existence of space or not is defined by the help of objects. If a volume is occupied by objects, then there is no space in that volume; If a volume is occupied by space, then there is no object in that volume. The surface of an object is both the boundary between space and object, and the volume of object and the volume of space.

For this reason, space is relative to the object.

"Space" refers to an anti-object composed of antimatter combined with antimatter, and the size of an anti-object is the size of a volume. Theoretically, anti-objects are non-material, but objectively anti-objects are occupied by matter. For this reason, natural space is not "space", but can only be referred to as a gaseous object (or space where gas exists).

If these gaseous objects all become solid with physical changes, then the volume of the gas minus the volume of the solid is "space".

"Object" refers to a positive object formed by the combination of matter and matter. The size of a positive object is the size of a volume. Theoretically, positive objects do not contain antimatter, but objectively positive objects have antimatter.

For this reason, the density of the same substance is not different when it changes physically.

You mean QQ space, it's a platform to show yourself, you can write logs on it, listen to **, play photos, etc.

The meaning of space is an objective form of physical existence, expressed by length, width, height; A certain range in space.

1. The essence of space.

Space is a being, but not matter, it is just a container that holds the universe. Therefore, if space does not exist first, the universe has no place to live, and therefore cannot be created, and even if there is a seed of matter, where is it placed? Space is just a kind of void, there is no **, there is no beginning, and of course there is no end.

Whether it is before the "big **" or after the "big **", the space is placed there, waiting for the flower of matter to bloom.

2. Spatial dimension.

Space can be mathematically divided into dimensions, but it is only in three dimensions and above that you can create independent spaces with volumes. Therefore, the independence of matter determines that there is no one-dimensional and two-dimensional matter, so the material world only has three-dimensional space.

3. The space is not empty.

We often say that a vacuum is a place where there are no physical particles, but there is energy. Since gravitational and electromagnetic fields can propagate to infinity, even if we call space the void, it is by no means nothing, there are always photons and the like, but the density is different everywhere.

4. The scope of the space is clever.

Space is infinite, there is no distinction between inside and outside, so any point in it can be said to be the center of the universe, and any direction can be defined as east. The vastness of space provides a broad stage for the expansion and contraction of the universe.
