What is Space?

Alternate to Space

We human have no idea of what space is!
Here is a three-steps process to find out what space could be made of!

Process' synopsis

  1. Precisely spell out how we define space. Whether that definition fits nature's reality or not!
  2. Compile a list of all concepts of ours, other than space, that we can imagine.
  3. Make a choice!

Process' details

  1. What is the definition we may give to space?
    A characteristic of space is to be a volume that in spite of our senses of vision and touch cannot be empty.
    Per definition, should a volume be empty, it would be reduced to an infinitesimal (dimension less) point.
    Definition: Space is a volume that has to be occupied by something.
    Or space is a volume made of something we know.

  2. Now here is a compilation of all real things
    The specificity of a real thing is to be physical.
    And the physical can be broken down into two categories:

    • The material1

      That is all objects whether small such as an atom or big such as our sun.
      Note that the material can be invisible such as the molecules of air we breathe.
      Considering our human concept of matter, matter doesn't fill let alone make space.

    • The non-material or the im-material2

      There are at least four non-material yet physical entities we can think of.3
      1. Light rays.
        Light rays are physical because we do see them. Besides they warm up our skin, which is a definite indication of being physical.
        Yet light rays are not material as our own body is. Light rays have been found (by the science of physics) to have no mass; light rays are im-material like space.
        Light rays are a good example of a thing, which is physical but not material.
      2. Gravitation.
        The force of gravity is physical because it forces an object to fall.
        We can see an object falling. Gravitation is physical all right!
        Yet unlike light rays, we do not see gravitation!
        So gravitation, which is as immaterial as space, is also as invisible as space.
        Gravitation, which is outside of matter that is in the middle of space, is a good candidate as an alternate to our concept of space.
      3. Motion.
        Motion has this strange characteristic that we see material things in motion but not their very motion!
        Motion (per se) is invisible as the force of gravity is!
        As such motion, which is not material, is not considered to be physical either in the science of physics!
        Since we do experiment motion with our own body though (while walking for instance) motion is categorized here as being a physical entity (against physics teachings).
        And while at it, motion does move non-material things as well; light-rays, which are non material are always in motion!
        Because the universe is in expansion, motion is a better candidate yet as an alternate to our concept of space than gravitation is.
        Note that heat is made of the motion of the molecules of the hot body; as such heat is motion, heat belongs to this category "c" and doesn't deserve its own category within this list of non-material entities.
      4. Life.
        Life instead of inhabiting space as do light-rays, gravitation and motion, seems to be confined to matter.
        Because non-material light rays are in motion, motion is not confined to matter as life is.
        The phenomenon of life is not a good candidate as an alternate to space; because space is very likely not made of matter.

      In all four cases a., b., c., and d. these non-material, yet physical entities, interact actively (that is along time) with our body!
      As a matter of fact it seems that the happening along time characterizes the physical, which is exclusively non-material.
      Our feeling is that a material entity such as a rock or a chair doesn't need time to exist.
      Im-material yet physical entities, intricately intertwined with time, interact with our body in a more intimate way than material entities seem to do.

  3. Make a choice
    Matter can definitely not be identified to space. For space to comply with matter we would have to be able to feel space as we do matter!
    The only solution is to identify space to one of the four a., b., c. or d. non-material yet physical entity listed above.
    Proceeding by elimination, space cannot be identified to light rays, because at night we know space is still there but there is no light!
    Similarly space cannot be identified to life, which seems to be restricted to matter. And space is not made of matter.
    On the other hand space could be identified to gravitation, because we suspect that gravitation permeates the whole of the universe.
    Similarly space could be identified to motion because we know the Universe is in expension!4

    In that interpretation of Nature that is GRAVIMOTION, both space and time are replaced by MOTION.

A Glance at the Infinite Present

Note 1: This coincides more or less to what is labeled "matter" in the science of physics
Note 2: This coincides "less than more" to what is labeled "forces" in the science of physics
Note 3: Time does not belong to this list as time is non physical (just as space). Time, in our minds and in physics, runs independently of any physical entity.
Note 4: The author of this page does not think the universe is expending. But that has no effect on this interpretation of space: space can still be made of Brownian motion for instance.
