Space is the three-dimensional extent of the universe. Objects in space have the same properties everywhere, including relative position and direction. In other words, they’re all made of the same stuff. Whether you’re looking for answers to these questions or want a quick explanation, this article has some answers.

## Objects in space have the same properties everywhere

Objects in space have the same properties wherever they go, but their location is not the same everywhere. For example, scientists say Pluto and Neptune are in our solar system because of gravitational attraction. But the truth is that they are there because of the size and quality of the dust that created them.

### They have relative positions and direction

In geometry, position and direction are expressed by vectors. Each vector represents a direction and a distance from a starting point. When two vectors have the same dx and dy values, they have the same direction and distance. However, when two vectors have different values, the direction of the other vector is different.

Space is a three-dimensional field that contains objects. Each object has its relative position and direction. The coordinate system axes define this field. This space is made up of many different types of objects.

There are two main ways to view space and time. One is that they are aspects of the same entity, and the other is that they are different. There are some cases where one concept of time is used to describe the other. For example, the same object can have different properties in two locations, such as being smaller or larger.

Another way to think of space and time is as properties of a continuum. This implies that space and time are uniforms, which is why they do not have any variation in any direction. This property is known as isotropy. So, for example, the cosmic microwave background has the same effective temperature in all directions. This makes the universe appear to be homogeneous on huge scales.

### They are all made of the same stuff.

In traditional physics, space is a mathematical construct that serves as the background for objects in the universe. But the new theory of general relativity proposes that space is made of the same stuff as the objects. We can see this in fluids containing discrete molecules that bounce around. The effect of these discrete molecules creates the illusion of continuity on larger scales.

### They are all in the same galaxy.

There is a large CD in the middle of a group of galaxies. This CD is called the Giant Elliptical. The Hubble Space Telescope observed this galaxy cluster. It is over 300 million miles in diameter, three times the size of our Sun.

We observe other galaxies as fuzzy patches in the sky, but if we take long exposures on film, we see the spiral structure and star clusters.
