Ladies and Guys,
I do not understand fully, why the problematic of dark matter is so
much important from the aspect of information.
We, physicists either, cannot agree what is dark matter.
Several physicists interpret the notion in different ways, and this
ambiguity is reflected in the Fis discussion as well.
I have my own interpretation as well, what differs from that of most
physicists. (I do not want to bore you with my interpretation.)
We do not agree even in that, whether dark matter and dark energy
are the same. (According to me, they aren't. cf., e.g. my paper linked in
my signo)
From my aspects of symmetry/invariance, I'd add only one, I think
so, important issue:
all physicists agree in the conservation of mass in the universe,
but
- we do not agree which mass is conserved (i.e., it may be the
gravitational mass, or may be the sum of the gravitational and inertial
masses);
- many physicists are not aware that although "the mass"
(which?) is conserved, the value of the conserved quantity depends on the
reference frame from which we observe it.
The latter has two important consequences:
- once, there must be such a reference frame, in which the conserved
quantity of mass - counted on the basis of the first Noether theorem - is
minimal; in this case that reference frame is distinguished from all
other reference frames; and this distinction would contradict to one of
the basic principles of the relativity theory, according to which all
reference frames are equivalent.
- at second, if we would like to avoid this contradiction, there
must be such a gauge field, in the presence of which all reference frames
lead to the same amount of conserved mass. This means, there is not the
Lorentz transformation alone under which the mass will be conserved in
the universe, but the Lorentz transformation plus another transformation
in that gauge field (which should depend on velocity). (I proved the
existence of such combined transformation in a series of papers in
2009-12. It holds not only for mass.)
In short, I think, it is not our task to solve the problem of
"what is dark matter".
However, this remark does not mean a constraint to wish a happy new
year to all of you,
Gyuri
