formula is only an approximation that works pretty well when matter is
chilly, less than a few hundred thousand degrees or so, but it breaks down
entirely and produces ridiculous numbers when things get much hotter than
that for the same reason Newton's theory works pretty well at highway
speeds but not at starship speeds.

formula doesn't take into account the Special Theory of Relativity much
less the General Theory, but that wasn't Boltzmann's
​ ​
fault, he died several years before Einstein developed either theory.

​If protons or anything else ​
could move faster than light
(​they're called
​) ​
then I could
​use them to send ​
send you ​
​message that you'd receive before I sent it, and that would create logical
paradoxes. Also the mathematics clearly show that the faster a Tachyon
moves the less energy it has, one that was only slightly faster than light
would have a lot of energy but one 10^25 faster would have  almost no
energy. ​

Nobody knows what Dark Matter is but we do know that if it is to explain
observed galaxy formation and clustering (and that is after all the entire
point of the Dark Matter theory) then it must be made of very slow moving

​Because gravity is not the only tool regular matter has to help it form
larger structures, it also has chemistry and that is essential to get the
ball rolling; but Dark Matter doesn't seem to have anything equivalent to
chemistry.  When 2 microscopic particles of regular matter come close to
each other the gravitational force between them is utterly insignificant,
but microscopic particles can be and often are electrically charged, and
even when the overall particle is neutral one side of it is slightly
positive and the other slightly negative. The charge may be small but the
Electromagnetic force is over a billion billion billion billion times
stronger than gravity so it dominates on the small scale. Once the particle
has grown to a million tons or so gravity can start to have a small but
measurable effect, but as far as we know Dark Matter just has gravity and
so has no way to take the first few steps.    ​
