Critical
Density of the Universe

There
are several reasons as to why I claim that the popular concept of
a Critical Density to the Universe is simply wrong. This is quite
distinct from the assessment as to the actual density of the Universe
itself, and also different as to how the Critical Density is calculated. |
||

The most obvious
misunderstanding of the Critical Density is that at some earlier time,
the actual density of the Universe is going to be more than the Critical
Density of the Universe, regardless of the amounts concerned. Many
claims are made that the Universe is currently at that Critical Density.
So how could the Universe have expanded to the current density from
a state that was denser – if that more dense state would have
made it impossible for expansion to occur?
#1:
7.5x10^-16kg/km^3.
So if Critical Density prevents expansion, then the local galaxies
should have contracted into a single entity a long time ago.
So we let us examine how long it takes for 1kg of matter at the ‘Critical Density’ to coalesce when dispersed over space. To
do this we invert the Critical Density and then cube root that volume: |
||

The two objects of 1kg each must be placed about 370 thousand kilometres
apart according to popular astrophysics to counter the expansion
of the Universe, whereas in Sum Theory they need to be just 270
thousand km apart. These distributions in linear space thus represent
the claims to Critical Density. Then we apply gravity and we wait
and see if it takes the age of the Universe for them to pull together.
There
is a beautiful and neat feature of how gravity and density interact
that needs to be elucidated. Scenario However
in Scenario The
actual volume and mass make no difference to the time it takes
for them to attract together. So long as the volume and mass are
at the same proportion, the time to coalesce is identical. I am
uncertain if anyone has noticed this before, so I’ll just
call it the So
when I place the popular astrophysics amount of Critical Density
into Scenario All
that is actually required is the age of the Universe and a simple
calculation. But, of course Critical Density is actually a failed
concept for reasons And
it is this feature I have called the Next we have to consider the rate of expansion too. The OGS12 algorithm and the ordinary formulae (in the section to follow) only compute a static un-expanding Universe. But if we consider that some expansion in the past counterbalances some expansion in the future, we still get the Critical Density for now. So
in the next section let us double-check all these results using
conventional formulae: |
