Hello. My name is Jonathan Doolin and i've
got this project that i've been working
on for
many years but don't
 know what direction to move it in
let's start with a question about
molecular hydrogen
molecular hydrogen is basically two hydrogen atoms that are connected by
some kind of chemical bonds and
the uh... chemical bond is such that
it's not really that stable
if you put a lot of uh... molecular
hydrogen together in one place
um... it has a tendency at that
if it catches a spark or something like
that
and i guess if if there's allot of
oxygen around to use as fuel anyway it
will explode
but what if there is no oxygen around
then you just have this uh... molecular
hydrogen floating around in space
can you detect it?
can you detect it?
and the reason i'm asking this question
is not
really particularly because I'm
interested in chemistry or anything but
it's because of
this thing that
cosmologist call
dark matter
now dark matter
has a couple of
interesting features
we know dark matter is there because of
the way
spiral galaxies spin
compared to the way, say solar systems
spin
basically there's this distribution of
velocities: this planet is going to spin
around the stars faster than this planet
and this planet goes slower than say
this planet
but in a galaxy
we end up having situation where uh...
this part is spinning a little bit too
fast we have
in order for to spend that fast...
as fast as it does
we have to account for it by the idea
that there is matter in here that we
cannot see
the uh...
now the current thinking in cosmology is
there's two types of matter
baryonic and non baryonic
and the difference between them is
that baryonic matter is made of neutrons
and protons while
non baryonic matter is made of other
stuff
and another feature is
with baryonic matter
we can see it and with nonbaryonic matter
we can't see it
Now, the uh...
examples that they frequently use when
describing these things
is
monotonic hydrogen
and all of the hydrogen in our galaxy... All of the
hydrogen in our universe
has been mapped by the observation of the twenty...
centimeter
twenty one centimeter wavelength line of
hydrogen gas
and this is an amazing resource because um...
that twenty one centimeter line is
basically not blocked by anything it can
go anywhere in the universe so we can
see
all the way across the universe with
with this twenty one centimeter line
we can tell exactly how fast the
monotonic hydrogen is moving
because all we have to do check that
doppler shift on the uh... twenty one
centimeter line from the uh...
from that gas
But here's my issue...  That only detects
monotomic hydrogen
Molecular hydrogen does not produce that
uh...
that particular frequency of light
because what it is is it uh...
when an electron spontaneously changes
its orientation
when you got a paired electron
one of them changing its orientation
just causes the other one to change and
the uh... energy is immediately absorbed
so here's my conjecture
it's that the dark matter
that they're looking for
it's actually just molecular hydrogen
because uh...
we have no one means of detecting
molecular hydrogen
not if it's completely by itself
if it's not
around oxygen it's pretty stable it's
gonna just stay there until something
bothers it
what sorts of things with that um...
molecular hydrogen give you you would
get uh... fuel for the appearance the
second generation stars
you'd get uh... fuel for the periodic uh...
type one supernova explosions
I thing you'd have some explanation for
some of these strange structures
if you imagine the region inside
this shell being almost a vacuum and
then
a couple of jets coming out from some kind
of hyper no her supernova explosion or
coming out and resulting in as spinning
of the galaxy
would basically give those jets an
invisible substance that they could
run into and uh...
result in some of these formations that
would start spinning in then
so my conjecture... don't misunderstand it.
I'm not saying that there are pockets of
H2
in certain locations i'm saying that the
entire universe consists of
a more-or-less homogeneous
distribution of hydrogen gas
It's everywhere
in the universe.  There's no...
The only places where it empty
are these black areas
uh... inside
real near the uh...
real near the galaxies so uh...
basically solar wind is pushed
so solar wind and uh... supernova
explosions has pushed
the gas out away from that region
um...
so like
in this picture, the black areas
are actually full
of a uniform distribution of hydrogen gas  while
the region's inside that galaxies are
pretty much, over all, the same density as
out here except this stuff have clumped
together and caught on fire
so you may be wondering how
would that h2 have form
and
and to answer that question i kinda need to
know what pressures and temperatures
conditions can uh...
H2 form?
basically we have a hydrogen atom and
another hydrogen atom and we uh...
knocked them together
and
they will either stick together
or bounce off of each other
there's probably a very simple ah...
chemical question but i don't know how
to ask the question exactly
I can say at standard temperature and
pressure, hydrogen as a colorless
(Sorry, video cuts off)
odorless
(Sorry, video cuts off)
tasteless non-toxic  
(Sorry, video cuts off)
