There is NONE !
But you can assume anything you wish as a reference point ---
but you must realize that its arbitrary.
"Fixed in space" means that an object's position or orientation remains constant relative to a reference point or frame of reference. This term is often used in physics and engineering to describe an object's stability or lack of movement in a specific spatial context.
Object space refers to the 3D space in which an object exists, with coordinates defined by its size and position in relation to a fixed point of reference. Image space, on the other hand, refers to the 2D space in which an image is rendered for display, typically on a screen, with coordinates measured in pixels. The transformation from object space to image space involves mapping 3D objects to 2D images for visualization.
Any all-powerful creator god would probably be able to create an object whose position is absolutely fixed in space, but that would require the object to disobey the rules of nature. As far as I know, no deity has ever chosen to do that.
A fixed location in a space is called a fixed star.
A fixed location in a space is called a fixed star.
The celestion equator is not a fixed object; it is more like a direction in space. Or in this case, a set of directions.
a bearing is the direction one object is from another object.A bearing can be taken to a fixed or moving object, so a fixed bearing would be the direction towards a fixed object.
I am not quite sure what you mean with "fixed". If you mean the object is fixed in its position, or unmovable, such a thing doesn't exist in the real world. Whenever a force acts on an object, its movement will change, according to Newton's Second Law (acceleration = force / mass).
[object Object]
No, the volume of an object does not change when its size changes. The volume is a fixed measure of the amount of space that the object occupies and is calculated using specific dimensions. Changing the size of the object would involve altering these dimensions but would not impact the volume.
Its location in 3 dimensions of space and one of time. Usually in relationship with some fixed point.
A fixed location in space can be represented by coordinates such as latitude and longitude on Earth, or by celestial coordinates like right ascension and declination in astronomy. These values provide a specific reference point in space that can be used to locate and navigate to a particular position.
