2.1
The major characteristics of
dark matter and light propagation
The existence of dark
matter in universal space confirms a simple fact that there is the medium of
light propagation in the universe. The reasons is appearance, because the dark
matter posseseses some basic properties that a midium posseses, for example:
The composed matter in WG (is certainly much
smaller than elementary particles )and posseses an attractive force i.e. the
gravitational force, it is a kind of long range force, which can be
superpositioned.
Two composed matters can not be conbined to form a
new bigger particle by the gravitational force between them (that already has
been proved by physics because the gravitation is too weak to be a strong
force). So the composed pratical object of dark matter
belongs to the item of elestic matter.
2.2
The principle method of measurement of photometrical and the medium mass of
light propagation.
May be
somebody will question me that since the dark matter is the medium of light
propagation, why astrophysicists can not find it by optical instruments?
The answer is that today’s scientists can calculate the mass and energy of
luminous objects by testing the colour temperature of emitted light and the
temperature of any object. This only includes the mass and energy of luminance
matter and the kinetic energy of relevant matter (especially for gas matter or
fluid matter), ie. If it’s true that the light propagates and transmits by the
medium of dark matter, the measured results about the total universal mass by
photometrical method only includes the luminance objects and the kinetic energy
of matter in universal space, excluding the mass of the medium itself.
