The latest issue (May) of Sicentific American has a good article on
the violent process of collisions by which the planets in our Solar
System formed. It is a violent universe! We are lucky to be here.
Other Earth-like planets with whatever life they had may have been
plunged into the fires of the Sun. Others may have been expelled from
the Solar System into the darkness of interstellar space, their frozen
oceans, and perhaps spores of life, forever waiting for a planetry
spring that never comes.
In another article, besides the Pioneer anomolies, other anomolies
have been detected in the motions of long range probes as they come
back and pass the Earth's gravitational field. They end up moving
either slower or faster than Einstein's theory of graviation (GR)
would predict! This raises the question of whether a better theory of
gravitation is needed. SPED anyone?

There's always room for a better theory, especially if a supercomputer
simulation as based upon this new and improved theory is what brings
home the bacon (so to speak).
The public owns the world's fastest supercomuter node of 2048
extremely fast CPUs, plus hosting all the other necessary bells and
whistles of resources to go along for the ride. It's on lone to our
JPL/NASA, but apparently doing next to nothing most of the time.

Of course they do, because the present 'flat' version of GR describes
a universally-isotropic 'void-nothing' devoid of *density gradients*
in gravity wells.

Yeah. Recognizing the fact of *density gradients* in the SPED will not
only bring GR out of its 'flat' status, but recognizing the deep-past
*cosmological density gradient* will bring SR out of ITS 'flat' status
and lay to rest the "ever-accelerating expansion of the universe"
crap. |

Sounds a bit like a physics/science kind of revision, of the good ship
LOLLIPOP kind of status quo boat rocking revisions. This could get
real nasty.

Well, the perceived "ever-accelerating expansion" calls for the ad hoc
invention of "dark energy" to drive the expansion. And it's all based
on the assumption that space is a universally-isotropic 'void-nothing'
all the way back to the instant of the BB.
But if space is a profoundly real 'Something', a Fluid,
that underwent a precipitous density drop from the instant of the BB
that gradually leveled out to its present value, this would be termed
the 'cosmological density gradient' (CDG). And it would indeed account
for the most distant 1a supernova 'standard candles' appearing 'dimmer
than they should be'. "Ever-accelerating expansion" would become a
grand illusion, with no need for mythical "dark energy" at all. The
expansion curve would be shifted toward DEcelerating expansion and a
closed universe.
AND there would be a slowing of the clock rate
across the CDG as these guys recognize :
http://www.telegraph.co.uk/earth/main.jhtml?xml=/earth/2007/12/18/scitime118.xml
While their model abolishes any need for "dark energy", it
extrapolates to the eventual stoppage of time altogether, which is
impossible in the real universe. |

What's wrong with the universe being sucked out into the supposed
nothingness of less than one atom/ly3, and possibly doing this at .
5'c'?

I tend to like the closed universe, or the quantum string like
universe that's quivering but always connected in a loop.

Perhaps instead of dark energy it's merely an ISM that chuck full of
gravitons and photons trekking through the mostly dark matter of
perhaps 2 atoms/m3.

A closed-loop system is exactly what the CBB model proposes. The freon
cycle in a common 'fridgerator provides an excellent analogy, replete
with its 'hot' and 'cold' phases illustrating the pre-BB state and the
whole externalized universe, respectively. See -
http://community-2.webtv.net/oldcoot/ContinuousBigBang/
Notice the little embedded 'marble' (#1), representing the sphere of
our visible cosmos, the 'known universe'. In the freon analogy, that
sphere would be represented by a cluster of freon molecules wending
its way from the 'bang' point toward the final 'crunch' of re-
ingestion back into the compressor.
Notice that two distinct referance frames are
involved. From here inside the 'marble', a finite beginning-point and
end-point, the BB and 'Big Crunch', are experienced. But from the
'outside' frame, the whole process is seen, with each phase running
continuously at its own station on the cycle. Thus the CBB model
subsumes but does not negate the 'singular BB' idea. |

And incidently, the model proposed by Senovilla et al is congruent
with the 'cosmological density gradient' of the CBB model. That is,
there would be a precipitous slowing of the clock rate from the
instant of the BB.
http://www.telegraph.co.uk/earth/main.jhtml?xml=/earth/2007/12/18/scitime118.xml
So, what does this say about the perceived "age of the universe" ???
Vastly more 'ticks of the clock' will have transpired than allowed
under the Void-Space Paradigm which recognizes no 'cosmological
density gradient' or slowing of the clock-rate across said gradient. |

How many nearby items of significant mass, or passing through as rogue
stars with planets and moons do we have within a 12 ly radius?
Is our little passive solar system a rogue consideration?
What is the nearest tidal radius from a given stellar cluster?

So, how many hundred billion years old (your best swag) is our

A hellava lot more than the 14 billion or so presently assumed
(referring to the age of our 'decoupled marble' sphere of visibility
since it emerged from the BB). |

At an average expansion velocity of .5'c', in order to have covered a
100B ly diameter, we're looking at roughly 200 billion years (based
upon one singular BB expansion cycle). So hell yes, it's "a hellava
lot more than the 14 billion".

Talk about having another one of those bad God days.
Images of galactic encounters, of the worse possible kind.
http://groups.google.com/group/sci.astro.amateur/browse_frm/thread/59e1650e7a556dfd?hl=en#
The best of 59 examples of cosmic hell busting lose, not that many
other than these relatively old Hubble images of the anti-big-bang
exist. Each of these galaxies has a fairly horrific gravity/tidal
radius of several thousand light years (perhaps at least as great as
64r, if not 128r), not to mention the mutual attraction of whatever a
pair or more of these bad boys has to work with, whereas you might
like to further reconsider the mutual gravity/tidal binding grasp of
two or more such encounters is perhaps worth 4X the individual tidal
radius. (hard to avoid gravity, especially when it’s the only game in
town)
http://www.sciam.com/gallery_directory.cfm?photo_id=8153DC82-A24D-3D07-8B32672098BE3984
http://www6.comcast.net/news/science/galaxies/slideshow/view/1/
Try to remember that our moon and Earth represents a mutual tidal
grasp of better than 60r.

The Pioneer anomaly may be solved, DA.
It's due to uneven heating of parts of the spacecraft.

Cosmicly, heat dissipates ( and heat sinks absorb it ),
fueling all motion ( including life ), accruing entropy.
It's an eternal process.. the cooling / thinning never ends.
We've seen the entropy of our visible Universe accruing
over the last 13.7 giga years of colomolical time,
so your CBB model seems quite irrelevant to me.
In 1949, Einstein wrote:
“ A theory is the more impressive
the greater the simplicity of its premises,
the more varied the kinds of things that it relates
and the more extended the area of its applicability.
Therefore classical thermodynamics has made a deep impression on me.
It is the only physical theory of universal content
which, I am convinced,
within the areas of the applicability of its basic concepts,
▲ will never be overthrown ▲. ”.
Sir Arthur Stanley Eddington wrote:
“ If someone points out to you that your pet theory of the universe
is in disagreement with Maxwell's equations
— then so much the worse for Maxwell's equations.
If it is found to be contradicted by observation
— well, these experimentalists do bungle things sometimes.
But if your theory is found to be
against the second law of thermodynamics I can give you no hope;
▲ there is nothing for it but to collapse in deepest humiliation ▲. ”. |
